## 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 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

## About Ellipsis Labs

## Company Overview
- **One-liner**: Ellipsis Labs builds applications and infrastructure to create a transparent, high-performance foundation for decentralized finance, including the leading orderbook spot exchange on Solana.
- **Entity Type**: Private (Venture-backed – Series A+; total funding $44.3M)
- **Headquarters**: New York, New York, United States
- **Founded**: 2023 (first funding round)
- **Founders**: Jarry Xiao (Co-Founder); also noted as a key executive (other co-founders not publicly named)

## Core Business
- **Primary industry**: Decentralized Finance (DeFi) / Financial Services / Blockchain Infrastructure
- **Target customers**: Institutional and retail traders, DeFi protocols, developers building on Solana and Ethereum
- **Mission or purpose**: "To rebuild the foundation of modern finance" – making finance transparent and performant by combining the verifiability of DeFi with the speed of traditional finance.

## Products & Services
- **Phoenix**: A fully on-chain limit orderbook spot exchange on Solana. Capital-efficient and verifiable, it has processed over $70B in unincentivized trading volume.
- **Phoenix Perps**: Professional-grade perpetual futures on Solana with low latency, low fees, and consistent performance.
- **Atlas**: A Layer 2 blockchain that brings Solana-level performance to Ethereum scale, designed for high-performance DeFi applications.
- **Open Source Contributions**: Includes "Verifiable Build CLI" (trustless verification of on-chain deployments) and research contributions via Umbra Research.

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed
- **Key Metric**: Total funding raised – $44.3M (as of October 2024)
- **Notable Investors/Partners**: Electric Capital (led seed), Paradigm (led Series A), Haun Ventures (led latest $21M venture round); also supported by Anatoly Yakovenko
- **Growth Signals**: Headcount grew 60% YoY to 21 employees; Phoenix achieved $70B+ in unincentivized trading volume; expanding product lines (Atlas L2, Perps) and active hiring across engineering, design, and marketing.

## Competitive Advantages
- **Fully on-chain orderbook**: Unlike many DEXs, Phoenix uses a traditional limit orderbook model (like Nasdaq) but entirely on-chain, offering capital efficiency and transparency.
- **Performance**: Leverages Solana’s low-latency environment (400ms block times) while adding L2 scaling via Atlas for Ethereum compatibility.
- **Verifiability**: All products are auditable and trustless, bridging the gap between TradFi and DeFi.

## Strategic Focus
- **Scaling verifiable finance**: Expanding Atlas as a blockchain for verifiable financial applications.
- **Product expansion**: Growing perpetual futures (Phoenix Perps) and continuing to improve the spot exchange.
- **Ecosystem contribution**: Increasing publicly available DeFi research and developer tools (Verifiable Build CLI) to strengthen ecosystem trust.
- **Talent growth**: Hiring aggressively for senior roles and new grad/intern positions to scale the team.

## Why Work Here
- **Culture**: In-person, collaborative, and mission-driven. Office in New York (Civic Center). Team is described as “work hard, build fast” with regular team offsites and social activities.
- **Compensation**: Above-market salaries (e.g., $150K–$250K base for engineers), generous equity, performance bonuses, and 401(k) matching.
- **Benefits**: Full health/dental/vision coverage (90% of premiums for you and family), unlimited PTO, daily lunch/dinner at office, commuter benefits, FSAs, and conference travel stipends.
- **Engineering focus**: High autonomy, low process—results matter. Interview process is transparent: recruiter call → live coding → take-home project → full-day onsite (coding, system design, bug squash, culture fit).
- **Growth opportunity**: Joining early-stage team with strong funding and clear product-market fit; chance to shape DeFi infrastructure from the ground up.
