Sherlock exists to make open finance secure enough for billions of people to trust with real value. We believe sound money and reliable financial infrastructure should be basic human rights and that Web3 can only achieve that if it’s secure by design. Traditional audits alone don’t solve that problem. Sherlock connects every layer of protocol security through collaborative audits, audit contests, bug bounties, coverage, and AI-powered analysis. Each product reinforces the others, forming a lifecycle system that protects protocols from development through live operations. Sherlock is the only security provider that offers financial coverage after every audit, backing its work with up to $500K in post-launch exploit protection. The company has run more public audits than anyone in the space, securing code for the Ethereum Foundation, Aave, Optimism, Cosmos, MakerDAO (Sky), and dozens of other top teams. Sherlock is backed by Alliance, Archetype, IDEO, CoinFund, Lattice, Spartan, A Capital, and other leading Web3 and Silicon Valley investors.

- Talking directly to protocol teams using the product, identifying what they actually need, and converting those conversations into concrete product and UI changes (10x weight) - Shipping those product and UI changes yourself — you write the code, not just the spec (9x weight) - Improving the prompting, judging, deduplication, and false-positive reduction pipelines that determine which findings reach customers (8x weight) - Building and maintaining benchmarks so we can tell whether changes actually improve the product (7x weight) - Making product calls in ambiguous situations and pushing work forward without heavy direction (7x weight) - Working closely with Sherlock’s developers and security researchers to stay aligned on goals and ship the right things (6x weight) - Staying current with practical advances in AI and LLMs that improve developer velocity and product quality (4x weight)

- Senior-level Python experience with a track record of shipping SaaS or software products to production - Comfort owning UI work end-to-end in a modern frontend stack (we use Next.js / TypeScript): thinking through the UX flow, mapping out the possible states a screen can be in, and translating that into a working UI yourself. Not a designer role, but you genuinely enjoy this part of the job. - Daily use of LLMs in your workflow, plus hands-on experience shipping a feature whose value depends on LLM output quality — prompting, judging, retrieval, evals, or similar. - Comfortable on calls with technical customers — this is a recurring part of the job, not occasional. You enjoy turning a customer conversation into a product change. - High agency: comfortable working without a PM, designer, or eng manager handing you scoped tickets. You decide what to build, scope it yourself, and ship it. - Working hours that meaningfully overlap with US or EU timezones.

- Attractive base (payable in fiat or crypto) + material tokens/equity + benefits - Flexible time-off policy - Great healthcare - Multiple offsites each year in places like France, Argentina, Thailand, etc. - Own a core product area at the company leading the AI shift in blockchain security - Root access to the decision-making process/criteria in all areas of Sherlock and the ability to work directly with the founders - Move quickly and get stuff done on a small, elite team that has already made a big impact in the crypto space - Play a huge role in defining the future of Sherlock and accomplishing the goal of making crypto/DeFi accessible to everyone.
