## 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.

Combined, these products have facilitated over $285B in trading volume across Solana markets.

Ellipsis Labs is seeking an inaugural EVM Senior Smart Contract Engineer to join our team. In this role, you will:

- Develop and maintain critical smart contracts for the EVM, along with the appropriate monitoring systems
- Serve as in-house expert and mentor on the EVM

## QUALIFICATIONS

## REQUIRED

- Experience building, deploying, and maintaining EVM smart contracts in production
- Experience working with auditors
- Deep understanding of Ethereum and low-level EVM concepts
- 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 with cloud infrastructure, preferably AWS
- Experience with Rust or other statically typed languages
- Experience in quant trading or DeFi

## 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.
