About
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. Sherlock\'s Culture Mission focus:
Everyone is here to build the most trusted financial coordination system in history. Nothing less. Hard, smart work:
Sherlock’s edge is thinking clearly, working longer, and executing better than anyone else. Every decision starts from first principles. Owner mentality:
Team members act like owners, not employees. Nothing is “someone else’s problem.” Builder mentality:
Everyone contributes directly to output. There are no pure managers or “idea people.” Customer proximity:
We stay close to the protocols we protect and build with their perspective in mind. Professional-athlete standards:
Performance is measured, meritocratic, and transparent. High output is the baseline, not the exception. Directness and transparency:
Feedback is honest and fast. Clarity beats comfort, and open communication drives better results. The Role Sherlock is building an AI product for blockchain security. The core is already built and in customers\' hands. What it now needs is someone to sit between our customers — protocol teams shipping real money on-chain — and the product, and own the loop from "what do they actually need" to "shipped." This is a generalist product engineering role. You will talk to customers, decide what matters, and ship it yourself. You will move across the entire product surface: the UI that protocol teams use to submit code and read findings, the prompting and judging pipelines that decide which issues reach the customer, the benchmarks that tell us whether the system is actually getting better, and the product calls in between. The role is explicitly broad. We are looking for breadth, judgment, and ownership over deep specialization in a single area. Requirements 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. Nice to Haves Experience setting up evals, judging pipelines, or benchmarking for LLM systems to measure effectiveness and catch regressions. Familiarity with prompt engineering, evaluation frameworks, retrieval, and vector databases. Prior experience in fast-moving, underdefined startup environments. Familiarity with audits, bug reports, or security workflows. Familiarity with Solidity, EVM tooling (Foundry, Hardhat), or smart contract security. This role is not a fit if you are: A pure backend specialist, pure prompt engineer, or pure UI designer. Someone who can discuss ideas but rarely ships product themselves. Dogmatic about one function only and uninterested in working across the stack. Without Python experience or without genuine interest in UI work — both have been the most common reasons we have passed on otherwise strong candidates. What\'s in it for you 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.
