Senior Backend Engineer

$150k - $250k

Ellipsis Labs

Ellipsis Labs is a profitable, venture-backed New York-based startup building differentiated products and infrastructure in decentralized finance.

The company developed Phoenix, the leading order book spot exchange on the Solana blockchain, and a top 10 DEX (decentralized exchange) with>$50B in volume since inception in 2023.

Ellipsis Labs is building Atlas, a blockchain for verifiable finance. Verifiable finance enables financial applications to combine the performance of traditional finance with DeFi's transparency.

All roles are in the Ellipsis Labs office in New York City.

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
Required
  • 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
Benefits
  • Above-market salary and equity compensation
  • Unlimited and encouraged PTO
  • Health, dental, and vision insurance for employees and their dependents
  • Lunch and dinner provided at the office
  • Optional, company-paid travel to events and conferences

Compensation Range: $150K - $250K
