About this role
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 a Quantitative Developer - Risk to join our team. You'll take ownership of how we manage risk across the platform, from setting the parameters that keep our markets safe to building the infrastructure that lets us list new assets faster and support entirely new asset classes. In this role, you will:
- Maintain and improve the core on-chain margin engine and offchain risk services
- Own and maintain risk parameters across our supported assets, ensuring they reflect current market conditions and platform risk tolerance
- Support the end-to-end process of listing new assets, including scoping and implementing the unique risk considerations each asset requires
- Design and build the risk framework for emerging asset classes
- Build tooling and infrastructure that make risk management scalable
- Independently scope and drive large, ambiguous projects from specification through production, partnering closely with trading, engineering, and research
QUALIFICATIONS
REQUIRED
- A strong quantitative foundation (degree or equivalent experience in math, statistics, physics, engineering, computer science, or a related field) with demonstrated quant interest and aptitude, e.g., economic or financial modeling
- Experience building and shipping production software, not solely research or analysis
- Ability to make informed decisions independently and drive projects to completion with minimal oversight
- 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
- 3+ years of relevant experience (quant trading, quantitative research, risk management, or software engineering with a strong quant bend); exceptional new graduates from top-tier programs will also be considered
- Experience working with blockchain technology, specifically Solana
- Background in quantitative or prop trading, particularly with derivatives, perpetual futures, or options
- Familiarity with pre-IPO or private market funding structures
- Proficiency in Rust

RoleSprint is not the employer and not a recruiter. Applications are made on the employer’s own site and never reach us; what RoleSprint does is help you decide whether a role is worth your time and prepare for it if it is.
