Cork is building the first decentralized finance (DeFi) protocol for tokenized risk infrastructure, creating a peer-peer marketplace to price, hedge and trade risk for onchain assets. We are focused on building secure, capital-efficient primitives. The team has raised over $2M from OrangeDAO, a16z/CSX, Steakhouse, among others, and have closed another $5 million seed round from top tier investors and strategic partners in the space. The founding team are all serial entrepreneurs.
This role is a remote role compatible with EU or US timezones.
- Design, implement, and maintain Solidity smart contracts (vaults, liquidations, oracle integrations, interest-rate logic, governance).
- Own security end-to-end: write tests, lead internal reviews, and manage external audits (scope, vendor selection, fix/retrospective).
- Optimize for gas and safety (state layout, CEI, fail-closed patterns); ensure safe upgrades/migrations where applicable.
- Collaborate in a global, remote-first team across Product, Protocol Research, and Full-Stack to translate requirements into deployable code.
- Contribute to docs, run incident response drills, and improve developer tooling/CI for testing, fuzzing, and analysis.
- Start hands-on; grow to own contract architecture & process (review standards, threat-model templates, release gates).
- 3–7 years building & shipping Solidity smart contracts in DeFi (lending/AMMs, liquidations, oracles, interest models, governance).
- Deep security mindset: known vulnerabilities, MEV surfaces; comfortable reading audit reports and writing POC tests.
- Demonstrated experience managing an audit process (from scoping → fixes → sign-off).
- Experience working in a global, remote-first team with excellent async collaboration.
- Tooling: Foundry/Hardhat, Slither/echidna/halmos (or similar), fuzzing & differential testing, gas profiling/optimization.
- Evidence of impact in the wild: shipped protocols, EIPs/ERCs, on-chain track record, or notable OSS repos.
1) async application → 2) initial screen → 3) take-home assignment → 4) technical interview & deep-dive → 5) product & culture → 6) references & verification.
2) Respecting your time is important to us. Expect prompt and clear feedback at each step.
- A chance to be a foundational member of a novel new DeFi primitive that has the potential to move the needle on institutional adoption of DeFi.
- Join a passionate, fun and ethical team dedicated to disrupting traditional finance.
- Competitive compensation with token incentives and equity.
- Remote-first culture with flexible hours and a focus on outcome-driven performance.
- Team retreats 2x/year & unlimited PTO.
- Opportunity to make a global impact through improving your own body and soul by way of competitive recreational tennis.
