About the company
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 Senior Backend Engineer at Ondo, you’ll build and scale infrastructure that powers the next generation of financial products—both onchain and off. Our backend team is responsible for the APIs, services, and tooling that sit between users and decentralized protocols, enabling seamless, secure access to RWAs and DeFi strategies.
You’ll work across systems that manage everything from token onboarding and investor flows to bridging and custody integrations. You'll collaborate closely with product, smart contract, and frontend teams to define robust interfaces and deliver high-performance applications that are the backbone of our user experience.
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 scalable, secure backend systems and APIs for interacting with both onchain protocols and offchain infrastructure.
- Collaborate with smart contract engineers to define interfaces and workflows between backend services and blockchain networks (EVM and non-EVM).
- Own integrations with custodians, identity/KYC providers, payments infrastructure, and third-party blockchain tooling.
- Support internal ops, investor services, and compliance teams with automation, auditability, and observability tools.
- 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.
Requirements
- 4+ years of backend software engineering experience, ideally with strong familiarity in TypeScript, Go(Golang) or Python
- Strong understanding of distributed systems, system design, and API development.
- Experience integrating with cloud infrastructure (AWS preferred), third-party services, and security/compliance-sensitive systems.
- Demonstrated interest in Web3 or DeFi—whether through professional experience or side projects.
- Familiarity with EVM-based blockchains and smart contract interactions is a plus, but not required.
- Comfort operating in a fast-moving startup environment with high ambiguity and high ownership.
- Located in a US time zone (PT–ET)
Nice to haves
- Experience working with blockchain/Web3 data providers like The Graph, Alchemy, or Moralis.
- Prior work on tokenized asset platforms, DeFi protocols, or custodial/wallet infrastructure.
- Understanding of Solidity or other smart contract languages.
What we offer
- 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
