Qualifications
3+ years of C++ programming experience in institutional systems.
Previous institutional DeFi software‑engineering experience, including building production DeFi market‑making or other performance‑sensitive systems.

Hands‑on Solidity programming experience, with the ability to read, test, and debug smart contracts and reason about EVM execution, transaction failures, permissions, and upgrade mechanisms.
Understanding of on‑chain execution nuances such as transaction ordering and MEV related execution risks.
Experience working with traders and researchers in translating systematic trading models into production‑ready systems.
Preferred experience:
Experience with other programming languages commonly used across the DeFi space (Rust, TypeScript/JavaScript, etc…) is a plus

Experience with EVM‑compatible ecosystems and L2 networks (Arbitrum, X Layer, HyperEVM, etc…).
Experience supporting market‑making, CEX/DEX arbitrage, cross‑venue execution, or additional DeFi protocols such as lending, derivatives, and vaults.
Experience with handling performance‑critical RPC or node infrastructure, private transaction submission, bundles, or other chain‑specific execution tooling.
