Ellipsis Labs, Inc

New York, NY • On-site

Internship

Posted 5 days ago

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.
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
