Senior Backend Engineer (Trading Infrastructure) - Ondo Finance

About Ondo Finance

Ondo Finance's mission is to provide institutional-grade, blockchain-enabled investment products and services. We operate both a technology arm that develops decentralized finance technology and an asset management arm that creates and manages tokenized funds. We were the first company to tokenize exposure to US Treasuries and have since expanded into several other assets while incubating protocols supporting tokenized real-world assets and traditional crypto.

Founded by alumni from Goldman Sachs' Digital Assets Team, we are backed by top investors including Founders Fund, Coinbase Ventures, Pantera Capital, and Tiger Global. We are fully remote, with team members across the U.S.

About the Role

As a Backend Engineer on Ondo's market making team, you'll build and scale the infrastructure behind our trading stack—real-time systems that quote and hedge tokenized markets 24/7 across on-chain and traditional venues. This is a small, senior team working in Rust and Go with high ownership over live production risk.

You'll work across systems managing pricing, execution, and PnL accounting, integrating market data from both traditional venues and on-chain sources. You will collaborate closely with trading and infrastructure teams to define robust interfaces and deliver systems capable of handling real-time, high-throughput conditions.

Responsibilities

• Design and implement low-latency backend systems and APIs for quoting, hedging, and executing across on-chain and traditional trading venues.
• Collaborate with the trading team to define interfaces and workflows between pricing, execution, and market data services.
• Own integrations with market data providers, exchanges, and on-chain venues, including feed handling and order execution.
• Build reconciliation and data-integrity tooling to maintain consistent positions, fills, and PnL across live trading state.
• Establish and enforce backend engineering standards, best practices, and security protocols across the stack.
• Participate in code reviews and architecture discussions, fostering a culture of engineering excellence.

Requirements

• 4+ years of backend software engineering experience, with strong programming ability in Go or Rust and a willingness to work in both.
• Strong understanding of distributed systems, system design, and building services that operate under real-time or latency-sensitive conditions.
• Experience integrating with cloud infrastructure (AWS preferred), third-party services, and high-throughput, production-critical systems.
• Demonstrated interest in Web3, DeFi, or trading systems through professional experience or side projects.
• Comfort operating in a fast-moving startup environment with high ambiguity and high ownership over live production risk.

Nice to Have

• Experience with market data providers and protocols (Databento, SIP/prop equity feeds, venue WebSocket APIs).
• Prior work on trading systems, execution infrastructure, or market data infrastructure at a trading firm, exchange, or broker.
• Familiarity with market microstructure, order execution, or exposure to crypto venues and on-chain trading.

What We Offer

• Competitive compensation including salary, future token rights, and/or equity
• Full medical, vision, and dental insurance
• Flexible vacation policy (PTO)
• Remote-first collaborative culture
