Start the check, free

1What this role really is

You'll be diving deep into the guts of how our distributed network agrees on things. Think of it as building the digital 'nervous system' that ensures everyone sees the same truth, even when parts of the network are misbehaving. This isn't just about writing code; it's about understanding the fundamental laws of distributed computing and applying them to build incredibly robust, fault-tolerant systems. You'll own specific components of our consensus protocol, making sure they're performant, secure, and reliable. It's challenging work, honestly, but incredibly rewarding when you see your contributions making a real difference to the network's stability.

2What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

Go / RustAdvanced

Implementing new features, fixing bugs, and writing comprehensive unit/integration tests within existing codebases. You're comfortable with concurrency primitives and performance profiling in at least one of these languages.

libp2pIntermediate

Integrating existing modules (e.g., pubsub, Kademlia DHT) to build and maintain node communication functionality. You can debug basic network connectivity issues and understand message propagation.

Tendermint/CometBFT / RaftIntermediate

Deploying and configuring networks using these frameworks. You understand the basic state machine replication logic and can build or modify simple applications on top, diagnosing common liveness failures.

Docker / KubernetesIntermediate

Using containerised environments to run local testnets, reproduce reported bugs, and understand deployment configurations. You can build and manage Docker images for your components.

Prometheus / GrafanaIntermediate

Writing basic PromQL queries to monitor node health, block height, and peer counts from existing dashboards. You can identify unusual network behaviour and set up simple alerts for your owned components.

Git & GitHub/GitLabAdvanced

Managing complex branching strategies, resolving merge conflicts, and contributing effectively to a shared codebase using pull requests and code reviews. You're comfortable with advanced Git commands.

3What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing inWhere you are nowThe step above
Technical Approach for a New FeaturePropose an approach, but implementation details and overall design need approval from a Senior Engineer.Independently design and implement the approach for your owned component, consulting with a Senior Engineer for major architectural decisions or cross-component impact.Lead the design for a new feature across multiple components, making key technical decisions and guiding junior engineers.
Code Review ApprovalCannot approve peer code reviews; can provide feedback.Can approve routine code reviews for junior colleagues, but complex or critical changes should also be reviewed by a Senior Engineer.Can independently approve most code reviews, acting as a final gatekeeper for critical changes.
Production Deployment of a ChangeNo authority; code is deployed by DevOps after Senior Engineer approval.Requires explicit approval from a Senior Engineer and sign-off from QA. You'll be involved in the pre-deployment checks.Can authorise deployment of non-critical changes after QA sign-off; critical changes require Lead/Staff Engineer approval.
Tool/Library Selection for a ComponentSuggest tools for consideration.Propose and justify the selection of new libraries or tools for your owned component, with final approval from a Senior Engineer.Make independent decisions on tool/library selection within your workstream, considering broader team impact and future maintenance.

4How you'll be judged

The scoreboard, honestly: the hard targets, how often each one is actually looked at, and the quiet human signals that never make it onto a dashboard.

Code Quality (Critical Bugs)
Number of critical bugs found in your committed code post-deployment.
Target · < 1 critical bug per 5,000 lines of committed code over a 6-month period

You commit 10,000 lines of code in a quarter. If we find zero critical consensus-breaking bugs, that's a win. One critical bug means we need to review the process.

Test Coverage on New Code
Percentage of new or modified code paths covered by unit and integration tests.
Target · >90% line coverage on all new code contributions

When you submit a new feature for the mempool, the automated tests confirm 95% of your new code lines are covered, giving us confidence it won't break.

Task Completion Rate
Percentage of assigned development tasks (tickets) completed within the estimated sprint timeframe.
Target · 80% of assigned tickets closed within sprint estimates

Out of 10 tasks estimated for a sprint, you successfully complete 8 of them, showing good planning and execution.

Component Uptime & Stability
Uptime and error rate for the specific consensus components you own (e.g., peer discovery service, mempool synchronisation).
Target · >99.9% uptime and <0.01% error rate for owned components

The peer discovery module you're responsible for maintains 99.95% uptime and zero reported synchronisation errors over a quarter, even during network stress.

Documentation Clarity & Completeness
How well your code, design decisions, and protocol components are documented for others to understand and maintain.
  • Junior engineers can onboard to your component with minimal direct supervision. Your design documents are clear enough for senior engineers to review without needing constant clarification. Your PR descriptions explain 'why' as much as 'what'.
Proactive Issue Identification
Your ability to spot potential problems, edge cases, or performance bottlenecks in your owned components before they become critical issues.
  • You raise concerns about a potential network partition scenario during a design review. You suggest a pre-emptive optimisation based on observed testnet behaviour. You identify a subtle race condition during code review that others missed.
Collaboration & Peer Review Impact
The quality of your contributions to code reviews and technical discussions, and how effectively you work with other teams.
  • Your code review comments consistently help improve the quality or security of others' code. You contribute constructively to protocol design discussions, offering alternative solutions. You get on well with the QA team, helping them understand complex scenarios for testing.
Understanding of Distributed Systems Trade-offs
Your ability to articulate and practically apply concepts like the CAP Theorem and FLP Impossibility when making design choices.
  • During a design discussion, you can clearly explain why we're prioritising liveness over safety in a particular component, or vice-versa, and the practical implications. You can justify a design decision by referencing known distributed systems constraints.

5Would you like it

The honest version. What people enjoy, and what grinds them down.

What people enjoy
Solving Hard, Fundamental Problems

You get a buzz from tackling complex theoretical challenges and seeing your solutions work in practice. You're not satisfied with a 'hack' when a robust, elegant solution is possible.

Spending an afternoon modelling a new view-change mechanism on a whiteboard, then seeing it pass all Jepsen tests.

Building Reliable, Secure Systems

You're driven by the desire to build infrastructure that is incredibly robust and secure, knowing that real-world value depends on it. You take pride in code that simply works, all the time.

Successfully implementing a new cryptographic primitive that significantly hardens a core protocol component.

Continuous Learning & Research

You love diving into academic papers, experimenting with new ideas, and constantly pushing your understanding of distributed systems. The idea of staying static in your knowledge is a nightmare.

Reading a new paper on asynchronous BFT and immediately thinking about how it could apply to our current protocol.

What frustrates people
  • The Trilemma Prison: Constantly making painful, explicit trade-offs between decentralisation, security, and scalability. Any gain in one area almost always requires a sacrifice in another, and you're the one who has to make the call.
  • Catastrophic Bug Risk: The knowledge that a single logical flaw in your code, which might only manifest under specific network timings, could lead to the permanent loss of billions of pounds in assets. This leads to extremely slow, cautious, and stressful development cycles.
  • Impossible to Test Perfectly: You can run simulations for months, but you will never perfectly replicate the chaos, scale, and adversarial conditions of a live, permissionless global network. You ship code hoping your models were good enough, and that's a tough pill to swallow.
  • Explaining Asynchrony to Management: Trying to justify to non-technical stakeholders why a feature is taking 9 months, by explaining the complexities of proving a protocol safe in an asynchronous network model with Byzantine actors. It's like speaking a different language.
  • Research Debt & Paper Fatigue: The sheer volume of new academic papers published weekly means you are perpetually behind the curve. Differentiating between groundbreaking research and academic noise is a constant struggle.
What this role does not give you
  • A predictable 9-to-5 routine with no urgent, late-night debugging sessions.
  • The satisfaction of seeing every single piece of your code immediately deployed and used by millions (some core protocol changes take years).
  • A role where you can avoid deep theoretical computer science and focus solely on application-level coding.
  • A low-stress environment where mistakes have minimal consequences.

6Who you work with

This role is absolutely critical for the health and reliability of our core network. Your work directly ensures the 'safety' and 'liveness' of the protocol—meaning the network won't break and will always make progress. Get it right, and we build trust and enable new applications. Get it wrong, and the entire system could grind to a halt or, frankly, lose a lot of money.

Inside the business
  • Senior Consensus Engineers (for technical guidance and code review)
  • Protocol Research Team (to understand new designs and requirements)
  • Quality Assurance & Testing Team (to help them build robust test cases)
  • DevOps Team (for deployment and monitoring support)
Outside the business
  • The wider developer community (through open-source contributions and documentation)
  • Validators/Node Operators (who run the software you build)

7What you need before you start

Not a wish list. The things you would be expected to already have.

  • At least 2-3 years of professional experience in software engineering, ideally with a focus on backend systems, networking, or distributed applications.
  • Proven ability to write clean, performant, and well-tested code in Go or Rust.
  • A solid academic background in Computer Science, or equivalent practical experience, with a good grasp of algorithms, data structures, and operating systems.
  • Demonstrable experience with version control systems, especially Git, in a collaborative team environment.
  • Experience debugging complex, multi-threaded applications.
  • A genuine passion for distributed systems and a track record of self-directed learning in this space (e.g., personal projects, open-source contributions, academic papers).

8What to practise next

Where the job is going, and what to do about it starting this week.

Protocol Optimisation & Performance Engineering

As network usage grows, every millisecond and every byte counts. You'll need to move beyond 'it works' to 'it works incredibly efficiently'—optimising message propagation, parallelising validation, and reducing latency will become even more critical.

Network Latency Minimisation · Parallelisation Strategies · Resource Contention Management

  • This month: Deep dive into Go/Rust's profiling tools (e.g., `pprof`, `perf`). Pick a component you own and identify its current performance bottlenecks.
  • Next quarter: Research and propose a specific optimisation for one of your components, backed by benchmarks and data. Implement it and measure the impact.
  • Month 4-6: Study papers on network optimisation techniques for distributed systems. Experiment with different message encoding schemes or gossip protocols.
  • Ongoing: Regularly review performance metrics for your components and look for opportunities to improve efficiency.

Quick win: Run a profiler on your current code. Often, the biggest bottlenecks are in unexpected places. Just understanding *where* the time is spent is a huge first step.

Advanced P2P Network Architecture

Simply using libp2p out-of-the-box won't be enough for long. You'll need to understand how to design custom transport protocols, implement novel sybil resistance mechanisms, and make strategic decisions about network topologies to ensure resilience and decentralisation at scale.

Custom Transport Protocols · Sybil Resistance Mechanisms · Network Topology Design

  • This month: Read the libp2p specification in depth. Understand how its different modules (DHT, pubsub, discovery) work under the hood.
  • Next quarter: Research different sybil resistance mechanisms (e.g., Proof-of-Work, Proof-of-Stake, identity-based) and their trade-offs. Think about how they could be integrated into our network.
  • Month 4-6: Experiment with building a small, custom P2P network using raw sockets or a minimal networking library to understand the fundamentals.
  • Ongoing: Follow research in P2P networking and decentralised identity. Look for opportunities to contribute to open-source P2P projects.

Quick win: Try to implement a very basic gossip protocol from scratch in Go or Rust. It's a great way to learn the low-level details of P2P communication.

9Staying current once you are in

What people here do to keep up
  • Actively contribute to open-source projects in the distributed systems or blockchain space. This is a fantastic way to build a portfolio and demonstrate your skills.
  • Attend industry conferences (e.g., Devcon, RustCon, GopherCon) and academic workshops (e.g., SOSP, OSDI, PODC) to stay current and network.
  • Participate in online courses or specialisations focused on advanced topics like formal methods, advanced cryptography, or network security.
  • Regularly read academic papers and technical blogs from leading researchers and projects in the field. Set aside dedicated time for this, it's that important.
  • Mentor junior engineers or participate in internal knowledge-sharing sessions. Teaching others is one of the best ways to solidify your own understanding.

10How the AI economy is changing work like this

Before we ask anything of you, here's what we can already say about AI and work of this kind:

The new skill this role is being asked for: Formal Methods & Protocol Verification

As protocols become more complex and handle greater value, 'testing' isn't enough. Mathematically proving correctness using formal methods is becoming a non-negotiable standard to prevent catastrophic bugs. We're seeing more and more projects adopt this, and frankly, it's a huge differentiator.

We'll only ever tell you what we can actually back up. No hype, no scare tactics.

The ten Future Fluencies

Zavmo analysis

The credential is what you can do today. These are what keep you valuable.

A qualification proves you can do the job as it's defined today. These ten are what decide whether you're still the obvious person for it in five years. They're the capabilities employers are now writing into senior roles faster than people are learning them. Zavmo weaves them through whatever you study, so you come out with both: the credential and the fluency.

The highlighted ones are the Fluencies your role leans on hardest, from how Consensus Engineer is actually changing. In about two minutes, the free confidence check asks where you stand on each of the ten. That's the whole check, and it's what makes the plan yours rather than generic.

  1. Your actual work Every lesson is taught against a live piece of your own work, not a worked example from a textbook.
  2. What you already know The first conversation finds your starting point, so you skip what you can already do and spend the time on what you cannot.
  3. The conditions you learn under Not a learning-styles quiz. The evidence does not support those. The dimensions the research does back, read once and used to shape the plan.
  4. How far you got last time It picks up mid-thought. The tutor knows what you said, what you struggled with, and what it asked you to try.
  5. Which tutor suits the moment Twelve of them, each for a different kind of thinking. The one who walks you through a first idea is not the one who stress-tests it.

  1. Senior Consensus Engineer

    3-5 years from Consensus Engineer

    From owning a component to designing and leading significant improvements to existing protocols, mentoring junior engineers, and making key technical decisions.

    • Protocol Design & Architecture: Designing new modules or significant modifications to existing protocols from scratch.
    • Advanced Formal Methods: Writing and verifying formal specifications for critical protocol components.
    • Performance Optimisation: Deep expertise in optimising distributed systems for extreme throughput and low latency.
    • Mentorship: Guiding junior engineers through complex technical challenges and code reviews.
Working with AI on the job

Working with AI

Where AI is starting to help

Let's be honest, a lot of the heavy lifting in consensus engineering can be incredibly time-consuming. From drafting formal specifications to hunting down elusive concurrency bugs, it's often a grind. But what if you could offload some of that cognitive load and accelerate your research and development? That's where AI comes in.

We're investing heavily in AI tools to make our engineers more productive, not to replace them. For a Consensus Engineer, this means using AI to tackle the most tedious or computationally intensive parts of your job, freeing you up to focus on the truly hard, creative problem-solving that only humans can do. Think of AI as your super-smart, tireless assistant.

Formal Spec Generation & Verification

Imagine translating a high-level English description of a new protocol feature into a TLA+ or Coq specification in minutes, not days. AI tools can help draft these specs and even assist in running initial proofs, catching logical flaws and missed edge cases far earlier. This means less manual, painstaking work and more time for actual design.

Game-Theoretic Simulation

For Proof-of-Stake systems, understanding validator behaviour is crucial. AI-driven agent-based modelling can simulate thousands of rational and irrational validator nodes, helping you analyse the economic security of your protocol design. This uncovers unexpected emergent strategies that could break the protocol, weeks before you'd find them manually.

Accelerated Research Synthesis

The volume of new academic papers on distributed systems and cryptography is overwhelming. Use a specialised AI research assistant to ingest, summarise, and find thematic connections across hundreds of papers. Ask it, 'What are the latest approaches to asynchronous BFT that don't rely on a common coin?' and get concise answers, saving you hours of literature review.

Concurrency Bug Detection

Concurrency bugs are the bane of distributed systems. Advanced, AI-powered static analysis tools, specifically designed for languages like Go and Rust, can identify subtle data races, deadlocks, and atomicity violations in consensus code. These are the bugs that traditional linters and tests often miss, preventing days or weeks of painful debugging.

The honest bit

You’ve started things before

Most of them were built for a room full of people who aren’t you. A cohort moves on whether or not your week allowed it, and by the third week the thing you’re behind on becomes the reason you stop opening it.

There’s no cohort here, and no timetable to fall behind. Before anything starts, Zavmo asks when you’re sharpest and how long you can realistically sit down for, then builds the sessions around those answers. A bad fortnight changes your pace. It doesn’t put you behind.

And you only pay once you start learning. Searching and planning are free, and you can cancel any time — so the cost of finding out is an afternoon, not a year.

What it costs

Less than one coaching session. Every month.

A single career-coaching hour costs more than a month of this, and it ends when the hour does. Zavmo doesn't. It's £70 a month, about £2.30 a day, for a companion that knows a Consensus Engineer, works on the job you actually do, and keeps going at your pace rather than a timetable's.

  • Searching and planning stay free. You only pay when you start learning.
  • Your credits are yours. Regulated, and they don't vanish when a subscription ends.
  • Cancel any time and billing stops. No notice period, no minimum term.

Your path, personalised

You have the map. Walking it is the part we do together.

This route runs to 1 national skill standard. That is a real journey.

Zavmo shapes a learning experience as unique as you are. It fits how you learn, your pace and the work you already do. Every step stays benchmarked to recognised national standards. That’s the plan for becoming a Consensus Engineer: personal to you, and it still counts. The first steps are free.

If you leave this industry

The skills you'll build as a Consensus Engineer are highly transferable. You could move into core protocol development for other blockchain projects, work on high-performance distributed databases, contribute to critical infrastructure at major tech companies, or even pursue academic research in distributed systems or cryptography.
