Job description

Ellipsis Labs is a profitable, venture-backed New York-based startup building sustainable and efficient DeFi protocols on high-throughput decentralized infrastructure. Our long-term goal is to build a better financial system.

Our flagship product, Phoenix Perpetuals, brings professional-grade perpetual futures to Solana. Building on our experience developing efficient markets, Ellipsis Labs also operates SolFi, a proprietary automated market maker that provides efficient liquidity for key trading pairs. Our foundational product, Phoenix Legacy, is a limit order book on the Solana blockchain that established our expertise in operating high-performance markets. Combined, these products have facilitated over $285B in trading volume across Solana markets.

  • Ensure the security and monitoring of critical production systems

Qualifications

  • 3+ years of experience with Unix systems and DevOps

  • Experience with cloud infrastructure, preferably AWS

  • 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

Preferred

  • Experience working with blockchain technology, preferably Solana
