Ellipsis Labs is a profitable, venture-backed New York-based startup building differentiated products and infrastructure in decentralized finance. The company is the developer of Phoenix, the leading order book spot exchange on the Solana blockchain, and a top 10 DEX (decentralized exchange) with >$70B in volume since inception in 2023. Additionally, we are one of the most active and prominent on-chain market makers in crypto.

Ellipsis Labs is seeking a Senior Backend Engineer to join our team. As an early-stage startup, we appreciate bright generalists who can iterate and ship quickly. In this role, you will:

• Build and maintain scalable production services. We currently support thousands of QPS, and future systems will need to handle at least another order of magnitude.
• Implement systems to monitor performance at the micro- and nano-second level.
• Drive ambitious engineering initiatives (for example, realtime data indexing at scale) from inception to completion: specification, architecture, implementation, testing, monitoring, and maintenance.

• 3+ years of experience building and maintaining production-grade software systems (preferably in Rust, C++, C, or Golang), with high-quality and well-documented production code.
• 3+ years of experience with Unix systems.
• Experience working with cloud infrastructure, preferably AWS.
• Ability to make informed engineering decisions based on relevant business context.
• 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.

• Experience working with blockchain technology, specifically Solana.
• Experience in quant trading or fintech.
• Proficiency in Rust.
