About the role

Ellipsis Labs is a profitable, venture-backed New York startup building performant DeFi protocols on high-throughput decentralized infrastructure. Our long-term mission is to build a more efficient, transparent, and fair financial system.

Our flagship product, Phoenix Perpetuals, brings professional-grade perpetual futures to Solana. Phoenix has processed over $4 billion in trading volume and is growing 20% month over month, adding to the more than $300 billion our products have facilitated to date. Behind Phoenix is a lean, high-caliber team with experience at top trading firms, blockchain companies, and tech companies.

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

QUALIFICATIONS

- 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

PREFERRED

- Experience working with blockchain technology, specifically Solana

- Experience in quant trading or fintech

- Proficiency in Rust
