  • 3+ years of experience building and maintaining production-grade software systems with high-quality and well-documented production code

  • 3+ years of experience with Unix systems

  • Experience working with Rust or other statically typed languages

  • Experience working with cloud infrastructure, preferably AWS

  • Ability to make informed engineering decisions based on relevant business context

  • A demonstrated track record of high agency, willingness to dive into unfamiliar technical and non-technical areas, and a team-first attitude

  • Passion for decentralized finance


  • Experience working with blockchain technology, specifically Solana

  • Experience in quant trading


  • Above-market salary and equity compensation

  • Unlimited and encouraged PTO

  • Health, dental, and vision insurance for employees and their dependents
