We are seeking a Senior Smart Contract Engineer with deep experience in Solana development to help build the next generation of on-chain financial infrastructure. You will work closely with a small, fast-moving team to architect, implement, and optimize high-performance smart contracts that power our core products.

While Solana expertise is preferred, strong candidates with backgrounds in other Web3 ecosystems (e.g. Solidity, WASM-based runtimes) are also encouraged to apply, especially with significant Rust experience.

Qualifications:

  • 1+ years of hands-on Solana development (Anchor preferred).
  • 2+ years of Rust experience
  • Strong quantitative skills: comfortable reasoning about complex system behaviors, risk models, and advanced calculations.
  • Startup mindset: bias toward ownership, adaptability, and shipping high-quality work quickly.
  • Web3 fundamentals: solid grasp of core blockchain concepts (accounts, programs, oracles, cross-program invocation, cryptography basics, etc.).

Nice-To-Haves:

  • Experience with DeFi protocols, risk engines, or on-chain financial primitives.
  • Contributions to open-source Defi or Blockchain projects.
  • Typescript experience, especially around integrating with smart contracts.

Role:

  • Own major components of the protocol stack and drive initiatives in a fast-moving startup environment.
  • Analyze external smart contracts and protocols for compatibility, risks, and integration opportunities.
  • Design and build robust integrations with third-party contracts and on-chain systems.
  • Collaborate with data engineering teams to index, structure, and validate diverse on-chain market data.
  • Ship high-quality features for our core Solana smart contract products.
  • Write comprehensive tests and harden contract security.
  • Work closely with frontend teams to model and visualize instruction flows, account relationships, and program logic.

Working with us has many perks, including: competitive salary, equity, token allocation, full benefits, unlimited PTO, and more.
