6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Security Audit Pass Rate

Percentage of smart contracts and blockchain architectures that pass third-party security audits with zero critical or high-severity findings on the first pass.

Target · 95% initial pass rate for critical/high severity

Designed a new DeFi lending protocol; the external audit found only two medium-severity issues, which were fixed before launch. That's a pass.

Gas Cost Optimisation

Average gas cost of deployed smart contract functions compared to initial benchmarks or industry best practices.

Target · Within 10% of target benchmark for key operations

Optimised the ERC-20 transfer function, reducing gas costs by 15% compared to the standard OpenZeppelin implementation, saving users £100s daily.

Architectural Design Adoption Rate

Percentage of your proposed architectural designs that are approved and successfully implemented by the development teams without significant deviation.

Target · 80% adoption rate

Out of five major project designs presented this quarter, four were fully adopted and are now in active development, showing strong alignment and clarity.

Technical Debt Reduction (Blockchain Specific)

Identified and resolved specific blockchain-related technical debt, such as improving contract upgradeability patterns or standardising node deployment configurations.

Target · Reduce identified critical tech debt items by 20% per quarter

Led the initiative to refactor our legacy NFT contract's upgrade mechanism, making future updates significantly safer and cheaper. This closed three high-priority tech debt tickets.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy

Solving Hard, Novel Technical Puzzles

You thrive on dissecting complex, uncharted problems. When a new Layer 2 scaling solution emerges, your first thought isn't 'more to learn,' it's 'how can we use this to solve X?' You enjoy the intellectual challenge of architecting systems where the rules are still being written.

Spending a week designing a novel cross-chain communication protocol to enable a new product feature, knowing there isn't an off-the-shelf solution.

Building the Future of Digital Trust

You're genuinely excited by the promise of decentralisation and the potential for new forms of digital ownership and coordination. You want to be at the forefront of building systems that are transparent, secure, and empower users, rather than just another CRUD app.

Seeing a smart contract you designed successfully execute thousands of transactions without a hitch, knowing it's creating verifiable, immutable records.

Mentoring and Shaping Technical Talent

You get a real kick out of helping others grow. When a junior developer is stuck on a Solidity bug, you enjoy guiding them to the solution, not just giving them the answer. You like establishing best practices and seeing the team improve because of your input.

Running a workshop on advanced smart contract security patterns for the dev team, then seeing them apply those learnings in their code reviews.

What frustrates people

Constantly fighting the urge to use blockchain for every problem, even when it's overkill.
Dealing with immature development tools and ever-changing standards.
The significant effort to make a PoC production-ready (security, monitoring, recovery).
Explaining the unpredictable nature of gas fees to Finance, repeatedly.
Designing around regulatory uncertainty, only for new guidance to force a redesign.
The ever-present fear of a smart contract exploit due to a subtle bug.

What this role does not give you

A fully stable, predictable tech stack that rarely changes.
A clear, linear path where every project you design goes straight to production.
The luxury of working in a domain with perfectly mature, bug-free tooling.
A role where you don't have to explain complex technical concepts to non-technical people.
A low-pressure environment where security mistakes have minimal consequences.

8Who you work with

You'll directly influence the technical direction and success of our blockchain initiatives. Your designs will dictate the security, scalability, and cost-effectiveness of our decentralised applications. Get it right, and we build trust and innovation; get it wrong, and we face reputational damage and financial losses. You're essentially safeguarding our future in the Web3 space.

Inside the business

Product Managers (for defining requirements and features)
Engineering Teams (for implementation details and challenges)
Security & Compliance Teams (for ensuring regulatory adherence and robust defence)
Legal Department (for smart contract legality and data privacy)
Other Architects (for cross-system integration and standards)

Outside the business

Third-party Audit Firms (for smart contract security reviews)
Technology Vendors (for platform selection and integration)
Industry Consortiums (for standards and best practices)
Clients (for understanding their needs and presenting solutions)

9What you need before you start

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

Proven experience (5+ years) in software architecture, with at least 3 years specifically focused on blockchain or distributed ledger technologies.
Demonstrable expertise in designing and deploying complex smart contract systems on at least one major blockchain platform (e.g., Ethereum, Solana, Hyperledger Fabric).
A strong portfolio or track record of successfully delivered blockchain projects, ideally including some that have gone to production.
Advanced proficiency in at least one smart contract language (Solidity, Rust) and associated development frameworks (Hardhat, Truffle, Foundry).
A deep understanding of cryptographic principles, distributed systems, and consensus mechanisms.
Experience leading technical discussions and mentoring junior developers.

10What to practise next

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

Advanced Smart Contract Security & Formal Verification

As smart contracts control more value, the cost of bugs skyrockets. Manual audits aren't enough. Formal verification, while complex, offers a way to mathematically prove contract correctness, and its tooling is improving.

Month 4: Attend a workshop or online course on formal verification for Solidity.

Quick win: Integrate more advanced static analysis tools into your CI/CD pipeline beyond basic linters. Get comfortable with tools like Slither for deeper vulnerability detection.

Decentralised Identity (DID) & Verifiable Credentials (VC)

The move towards user-owned identity is a core Web3 promise. As enterprise and regulatory needs mature, integrating DIDs and VCs into our solutions will become essential for compliant and privacy-preserving interactions.

DID Methods: Understanding different decentralised · Verifiable Credential Data Model: How VCs are stru · Issuers, Holders, Verifiers: The roles in the DID/ · Wallet Integration: How DIDs/VCs are managed and p · Privacy Considerations: Designing for selective di

This month: Research the W3C DID and Verifiable Credentials specifications.
Month 2: Explore a DID/VC framework (e.g., SpruceID, Trinsic) and understand its SDKs.
Month 3: Design a hypothetical system where a user proves their age using a VC without revealing their exact birthdate.
Month 4: Build a simple PoC demonstrating a decentralised login flow using DIDs.

Quick win: Understand the core problem DIDs and VCs solve: user-centric, privacy-preserving identity. Follow projects like Worldcoin or Lens Protocol for real-world examples.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, the blockchain space is complex and moves fast. You're drowning in EIPs, new Layer 2 docs, and trying to keep your smart contracts secure. What if you could offload some of the heavy lifting and focus on the truly strategic architecture? That's where AI comes in.

We're not talking about replacing architects, but augmenting your capabilities. Imagine AI as your super-smart assistant, helping you audit code, simulate complex tokenomics, and digest mountains of technical documentation in minutes. This isn't just theory; we're actively integrating these tools to make your job more efficient and frankly, more enjoyable.

Smart Contract Auditing Co-pilot

Use AI tools like GPT-4 or specialised models (e.g., Mythril, Slither) to perform initial static analysis on Solidity/Rust code. It'll automatically flag common vulnerabilities like re-entrancy, integer overflows, and access control issues, giving you a head start before a human audit even begins. Think of it as a super-powered linter that catches the obvious stuff, freeing you up for the tricky logical flaws.

Tokenomic Model Simulation

Use agent-based modelling and AI to simulate the behaviour of a designed token economy. You can predict outcomes like token price stability, network participation rates, and vulnerability to economic exploits under thousands of different market scenarios. This means you can iterate on token designs much faster and with more confidence, reducing the risk of launching an unstable system.

EIP & Protocol Research Synthesizer

Use an LLM to ingest and summarise the latest, highly technical Ethereum Improvement Proposals, academic papers on consensus algorithms, or dense documentation for a new Layer 2 solution. You can ask it to 'Explain the security trade-offs of the new EIP-4844 like I'm explaining it to my CFO' and get a concise, digestible answer. No more sifting through hundreds of pages just to get the gist.

Whitepaper & Diagram Generator

Provide an AI with a structured outline and key technical details for a new project, and have it generate the first draft of a technical whitepaper or a stakeholder-facing project proposal. Use text-to-diagram tools to create initial versions of system architecture diagrams from a simple description. This saves you hours on initial drafting, letting you focus on refining the core ideas and ensuring accuracy.
