Senior Backend Engineer (Trading Infrastructure) [Remote]

Hi, we're Ondo Finance. Our mission is to provide institutional-grade, blockchain-enabled investment products and services. We have 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. We are also focused on incubating protocols that can support both tokenized real-world assets and traditional crypto.

Founded by folks from Goldman Sachs Digital Assets Team, we’re backed by some of the best investors in the world including Founders Fund, Coinbase Ventures, Pantera Capital, Tiger Global, and more. We are currently the leaders in the space in terms of AUM and are well capitalized to continue growing the firm. We're 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 that manage pricing, execution, and PnL accounting, integrating market data from both traditional venues and on-chain sources. You'll collaborate closely with the trading and infrastructure teams to define robust interfaces and deliver systems that hold up under real-time, high-throughput conditions.

This is a rare opportunity to build at the intersection of Web2 and Web3, in a fast-paced, high-ownership environment.

#### 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 so positions, fills, and PnL stay consistent 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, contributing to a culture of engineering excellence.

• 4+ years of backend software engineering experience, with strong programming ability in Go or Rust, and willingness to work in both.


• Strong understanding of distributed systems, system design, and building services that run 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—whether through professional experience or side projects.


• Familiarity with market microstructure or order execution is a plus, but not required.


• Comfort operating in a fast-moving startup environment with high ambiguity and high ownership over live production risk.

• 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.


• Exposure to crypto venues and on-chain trading.

• Competitive compensation including salary, future token rights, and/or equity (according to your preferences) — we're well-funded and believe that great talent deserves great compensation

• Full benefits (medical, vision, and dental) and flexible vacation policy (PTO)

• Small remote-first team across many countries — you'll be an early team member helping shape our vision, culture, and design practices

• A+ colleagues — our team includes alumni from: Goldman Sachs, Blackrock, Two Sigma, Bridgewater, SpaceX, AWS, Meta, Google, Pinterest, McKinsey, Circle, Uniswap, Phantom

• Best-in-class investors — we are proud to be backed by leading crypto experts and VCs, including Pantera Capital, Founders Fund and Coinbase Ventures
