▷ (3 Days Left) Senior Blockchain Developer

We’re hiring an experienced, pragmatic blockchain engineer to own core smart-contract development and backend integration work. You’ll build and test Solidity contracts (Foundry), implement secure MPC / BLS signing integrations, develop robust Python backend services that talk to exchanges and oracles, and help design production-grade token / stablecoin mechanics. You’ll be expected to ship high-quality, audited code and iterate quickly with product and security teams.

What you’ll do

• Design, develop and maintain Solidity smart contracts (wallets, vaults, stablecoin logic, tokenomics).
• Write thorough unit & integration tests using Foundry; fuzzing and property tests a plus.
• Integrate smart contracts with Python backend services (attestations, session tokens, keeper / monitoring services).
• Implement and integrate MPC / BLS signing flows with the backend and client SDKs.
• Integrate with third-party APIs : price oracles, DEXs, CEXs, fiat on / off-ramps (REST / WebSockets).
• Build secure mint / burn, collateral, liquidation, and fee systems for a stablecoin product.
• Hardening, code review, working with auditors; help prepare audit packs and remediation.
• Help run CI / CD, deployments, and maintain release processes for mainnet / testnets.
• Mentor junior devs and drive engineering best practices.
