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.

All roles are in the Ellipsis Labs office in New York City.

Ellipsis Labs is seeking software engineering summer interns to join our team in 2027. As an early-stage startup, we appreciate bright generalists who can iterate and ship quickly. In this role, you will:

  • Build real product features and/or platform components across the stack, front end, back end, infra, or on-chain, based on your skills and interest
  • Own scoped projects end-to-end: problem definition → design → implementation → testing → deployment → monitoring
  • Collaborate with design and engineering to deliver fast, reliable, and secure experiences
  • Instrument and improve performance, reliability, and observability; write clear tests and documentation

Qualifications

Required

  • Hands-on experience building software (courses, personal projects, research, or internships) in one or more languages such as TypeScript/JavaScript, Python, Rust, Java, C/C++; you write clear, tested code
  • Solid CS fundamentals (data structures, algorithms, systems thinking) and familiarity with Git and basic debugging
  • Ability to make informed trade-offs with business context; high agency and a team-first mindset
  • Curiosity about DeFi/crypto (prior domain experience not required)

Preferred

  • Experience in one or more areas: full-stack web (React/Javascript), backend APIs/services, infrastructure/DevOps (Docker, CI/CD, cloud), or on-chain/low-level systems
  • Familiarity with blockchain technology (Solana a plus)
  • Interest or experience in fintech/trading
  • Rust or TypeScript proficiency
