3What this role really is

This job is about designing the security foundations of Web3 protocols, building decentralised systems to withstand attack from day one. It means anticipating what an attacker might try, and shaping how user funds and critical data stay protected.

4What you'd actually use

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

Slither / Mythril Expert

You'll be integrating static/symbolic analysis into our CI/CD pipelines, evaluating and selecting new analysis tools for the organisation, and writing custom detectors to catch protocol-specific vulnerabilities that generic tools miss.

Foundry / Hardhat Expert

You'll architect the organisation's entire smart contract testing strategy, establishing standards for coverage, fuzzing, and fork-based testing. This includes designing frameworks for complex PoC exploits and white-hat counter-attacks.

Tenderly / Phalcon Expert

You'll deploy organisation-wide monitoring and alerting strategies, using platform data to inform risk models and security policies. During incidents, you'll lead deep forensic analysis and use simulations to predict complex transaction outcomes.

Forta Expert

You'll manage the entire portfolio of detection bots, developing and deploying custom bots to monitor for protocol-specific economic exploits and governance attacks. You'll also use Forta network data to advise on ecosystem-level threats.

OpenZeppelin Defender Expert

You'll architect the company's security operations and key management policies using the platform, designing and implementing automated security responses (Sentinels) and multi-sig contract administration workflows (Relayers). You're responsible for the overall OpSec posture.

Etherscan Advanced

You'll use advanced features and APIs to conduct large-scale on-chain intelligence, due diligence, and forensic analysis during investigations. This means tracing complex transaction flows and identifying interconnected contract relationships.

ServiceNow GRC / Archer Intermediate

You'll own the Web3 risk register within our GRC platform, providing comprehensive technical data on Web3-specific risks (e.g., smart contract bugs, oracle failure) and reporting on our crypto-risk posture to senior leadership and, eventually, the board.

5What 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 in Where you are nowThe step above
Security Architecture Design for New Protocols N/A - Executes designs provided by senior engineers. Proposes minor design improvements; executes specific security components. Designs significant security components; recommends architectural patterns.
Bug Bounty Payout Approvals N/A - Reports findings to senior team. Recommends payout amounts for low/medium severity findings. Recommends payouts for high/critical findings; manages communication with researchers.
Incident Response Strategy & Mitigation Executes specific tasks during an incident under direct supervision. Identifies incident scope; proposes initial mitigation steps. Leads a specific mitigation workstream; makes tactical decisions during an incident.
Hiring & Performance Management for Direct Reports N/A N/A Provides input on candidate interviews; mentors junior staff.

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.

Critical Pre-Deployment Catches
Number of high or critical severity vulnerabilities identified and remediated *before* a protocol goes live, which would have resulted in significant financial loss or operational disruption.
Target · Prevent at least one potential exploit per half that would have resulted in >£1M in losses.

Identified a reentrancy bug in a new lending contract during a final audit, preventing an estimated £2.5M loss had it gone to mainnet.

Incident Response Time-to-Mitigation
The average time taken from a confirmed critical security alert to the successful implementation of a mitigation strategy (e.g., contract pause, white-hat exploit, upgrade).
Target · Time-to-mitigation for critical incidents is < 30 minutes from alert to war room activation, and < 2 hours for full mitigation.

Detected an oracle manipulation attempt, activated the war room in 15 minutes, and paused the affected contract within 45 minutes, limiting exposure to £50K.

Bug Bounty Program Effectiveness
The ratio of unique, valid high/critical findings reported by external researchers to the total bug bounty payout, alongside the average severity of findings.
Target · Maintain a 'critical' finding rate below 5% of total valid reports and an average payout per critical bug below £50K, indicating robust internal security.

In Q2, only 3 critical bugs were reported out of 35 valid submissions, with an average payout of £30K, showing strong internal pre-screening.

Security Architecture Review Coverage
Percentage of new protocol features or major upgrades that undergo a formal security architecture review and threat modelling session *before* development begins.
Target · 100% of all new protocol features and major upgrades are reviewed at the design stage.

Ensured that the new cross-chain bridge design had a full threat model and security architecture sign-off before any code was written, identifying two potential bridge-specific attack vectors early.

Mentorship and Team Growth
How effectively you guide and develop junior members of the security team, helping them grow their technical skills and take on more complex responsibilities.
  • Mentors at least one junior engineer to promotion or lead audit responsibility per year. Junior team members consistently report feeling supported and learning new skills. You're regularly sought out for technical advice and guidance by your direct reports.
Strategic Influence on Protocol Design
Your ability to influence core development and product teams to adopt secure design patterns and prioritise security features, even when under pressure to deliver quickly.
  • Security considerations are consistently integrated into early design discussions. You're proactively invited to product roadmap meetings. Product teams regularly adjust their plans based on your security recommendations, showing they trust your judgement.
Clarity and Impact of Security Communications
How well you articulate complex Web3 vulnerabilities and their business impact to both technical and non-technical audiences, ensuring everyone understands the risks and necessary actions.
  • Executive leadership consistently understands and acts on your security briefings. Developers clearly understand the 'why' behind your remediation requests. Your incident post-mortems are clear, concise, and lead to concrete preventative actions.
Proactive Threat Hunting & Research
Your initiative in identifying new attack vectors, researching emerging Web3 security trends, and proactively integrating new defence mechanisms or tools.
  • You regularly present new threat intelligence to the team. You propose and implement new monitoring or analysis techniques before a known exploit emerges. You're seen as the go-to person for insights into the latest Web3 security landscape.

7Would you like it

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

What people enjoy
Protecting the Frontier

You're driven by the challenge of securing cutting-edge decentralised systems against sophisticated adversaries. You get a thrill from identifying a novel attack vector or designing a robust defence for a new protocol. This shows up in your proactive research and your dedication to thoroughness.

Spending extra hours researching a new Layer 2 bridge architecture to identify potential attack surfaces before the dev team even starts coding.

Architecting Resilience

You love building things that last, especially when it comes to security. The idea of designing a system that can withstand intense pressure and malicious intent really appeals to you. You'll find satisfaction in seeing your security designs implemented and holding strong.

Leading the design of a new multi-sig governance system, ensuring it has appropriate time-locks and emergency procedures built in from the ground up.

Mentoring & Leading

You enjoy guiding others, sharing your deep knowledge, and seeing your team members grow. You get satisfaction from helping junior engineers understand complex concepts and develop their own adversarial mindset. This means you're often found doing code reviews, pair programming, or just chatting through tough problems.

Helping a junior engineer debug a complex Foundry test case for a reentrancy vulnerability, turning it into a teaching moment about exploit patterns.

What frustrates people
  • Arguing with developers who insist on using outdated or forked versions of standard libraries (like OpenZeppelin) that contain known, patched vulnerabilities.
  • The constant race to stay ahead of attackers who are often state-sponsored, incredibly well-funded, and only have to be right once.
  • Dealing with the aftermath of a social engineering attack that bypasses all technical security measures you've put in place.
  • The sheer volume of new protocols and attack vectors emerging daily, making it hard to feel 'on top' of everything.
What this role does not give you
  • A predictable 9-to-5 schedule; incidents don't care about your bedtime.
  • Guaranteed immediate gratification; sometimes your best work is preventing something that never happens, and no one ever knows.
  • A slow-paced, low-stress environment; this is high-stakes, high-pressure work.
  • A role where you only write code; you'll spend a lot of time communicating, leading, and strategising.

8Who you work with

This role directly shapes the security posture of all new and existing Web3 protocols. Your decisions will protect user funds, maintain platform integrity, and safeguard the company's reputation. Honestly, a single security incident can wipe out years of hard work and millions in value, so your impact is absolutely critical to our long-term success and credibility in the Web3 space.

  • Deep expertise in Solidity and the EVM, including common vulnerability patterns and advanced exploit techniques.
  • Extensive experience with smart contract auditing tools (e.g., Slither, Mythril) and testing frameworks (e.g., Foundry, Hardhat), including writing custom detectors and complex PoCs.
  • Demonstrable experience leading incident response efforts for Web3 protocols, including 'war room' coordination and post-mortem analysis.
  • Strong understanding of decentralised finance (DeFi) mechanics, tokenomics, and the economic attack vectors prevalent in the space.
  • Experience mentoring junior engineers and leading small technical teams.

10What to practise next

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

Decentralised Identity (DID) & Verifiable Credentials (VC) Security

DIDs and VCs are foundational for the next generation of Web3 applications, enabling self-sovereign identity and privacy-preserving data exchange. Securing these systems against impersonation, credential forgery, and privacy breaches will be paramount. This goes beyond smart contracts into a new realm of cryptographic identity.

DID methods and registries (e.g., did:eth, did:web · Credential issuance, presentation, and verificatio · Cryptographic signatures and zero-knowledge proofs · Privacy-preserving attribute disclosure · Common attack vectors against DID/VC systems (e.g.

  • This quarter: Research the W3C DID and Verifiable Credentials specifications. Understand the core components.
  • Next quarter: Experiment with an open-source DID/VC framework (e.g., SpruceID, Trinsic) to build a simple identity flow.
  • Month 4-6: Analyse the security models of existing DID/VC projects in the Web3 space, looking for potential weaknesses.
  • Month 7-9: Propose security best practices for integrating DIDs and VCs into our future protocols.

Quick win: Read up on the concept of 'self-sovereign identity' and how it differs from traditional identity models. Start following thought leaders in the decentralised identity space.

Formal Verification for Smart Contracts

For mission-critical Web3 protocols, traditional testing and auditing might not be enough. Formal verification offers mathematical proof of correctness, eliminating entire classes of bugs. As protocols become more complex and high-value, the ability to apply and interpret formal methods will be a significant differentiator.

Specification languages (e.g., K-framework, Dafny) · Model checking and theorem proving techniques · Translating Solidity to formal specifications · Limitations and challenges of formal verification · Integrating formal verification into the SDLC

  • This quarter: Take an online course on formal methods or discrete mathematics to grasp the foundational logic.
  • Next quarter: Experiment with a formal verification tool for Solidity (e.g., Certora, K-framework for EVM) on a simple contract.
  • Month 4-6: Work with an external formal verification expert to understand their methodology and process.
  • Month 7-9: Advocate for and lead a pilot project to formally verify a critical component of one of our protocols.

Quick win: Read case studies of major protocols that have used formal verification (e.g., Compound, MakerDAO). Understand why they chose it and what problems it solved.

11Staying current once you are in

What people here do to keep up
  • Regularly contributing to open-source Web3 security tools or research projects.
  • Attending and speaking at major Web3 security conferences (e.g., EthCC, Defcon, Black Hat).
  • Participating in bug bounty programmes as a white-hat hacker, continuously honing your exploit discovery skills.
  • Mentoring junior engineers and actively sharing knowledge within the wider Web3 security community.
  • Staying current with academic research in cryptography, formal methods, and blockchain security.

  • Proof generation and verification mechanisms
  • Common ZKP vulnerabilities (e.g., trusted setup co
  • Formal verification techniques for ZKP circuits
  • Privacy implications and side-channel attacks

AI-Assisted Security Analysis & Red Teaming

Attackers are already using AI to find vulnerabilities faster. We need to use it better to defend. This involves not just using AI tools, but understanding how to 'jailbreak' them, how to fine-tune them for specific protocol analysis, and how to use them in red-teaming exercises to simulate advanced attacks. It's about turning AI into a weapon for defence.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, the Web3 security landscape is moving at light speed, and you're constantly battling sophisticated threats. You can't afford to get bogged down in manual, repetitive tasks. That's where AI comes in. We're not talking about replacing your brain; we're talking about giving you a serious force multiplier.

Imagine having a tireless assistant that handles the grunt work, sifts through mountains of data, and even drafts reports for you. This isn't science fiction; it's how our Lead Protocol Security Engineers are already working smarter, not harder. Here’s a peek at how you'll be using AI to dramatically boost your effectiveness and focus on the truly strategic, complex challenges.

Automated Static Analysis Triage

You'll use AI to sift through the raw output from tools like Slither or Mythril. It'll filter out the noise, identify common false positives, and prioritise high-confidence vulnerabilities based on patterns from past exploits. This means you spend less time sifting through irrelevant warnings and more time on real threats. Frankly, it's a game-changer for audit efficiency.

Anomaly Detection for On-Chain Activity

We'll train models on our protocol's 'normal' on-chain behaviour. The AI then provides real-time alerts on significant deviations – think unusual function calls, massive, unexpected fund movements, or sudden spikes in gas usage. It acts as an early warning system for exploits, allowing you to activate the 'war room' seconds faster than manual monitoring ever could.

AI-Powered Exploit Summariser & Threat Intel

Feed an LLM the latest hack post-mortems from Rekt News, Immunefi, or even obscure forum posts. It generates concise summaries of new attack vectors, vulnerable code patterns, and mitigation techniques. This keeps you and your team current without drowning in information overload, letting you focus on strategic defence planning.

Vulnerability Report Generation

After you've identified a bug and created a Proof of Concept, provide the vulnerable code, exploit script, and vulnerability type (e.g., 'reentrancy', 'oracle manipulation') to an AI assistant. It drafts a structured report with the background, impact, and recommended remediation steps, saving you hours of tedious writing per report. You'll still review and refine, of course.
