Senior Blockchain Engineer

As a Senior Blockchain Engineer at Ondo Finance, you own the design of smart contract systems across multiple blockchain ecosystems powering Real World Asset (RWA) tokenization. Your responsibility spans not just the contracts themselves, but how they're deployed, secured, monitored, and managed throughout their lifetime, and how they connect to the people and products that depend on them. You'll collaborate with product, legal, compliance, web, and ops teams to ensure contracts are technically sound, regulatorily aligned, and genuinely operable by the teams who rely on them day to day. This role shapes the future of finance by building systems that bring real-world assets on-chain while making those systems something a whole organization can build on with confidence.

What you'll do

• Design entire smart contract systems for Ondo's evolving product suite, covering new chain deployments, novel DeFi interoperability and bridging solutions, and DeFi protocols, with security, operability, and long-term maintainability built in from the start
• Own contract security across the full lifetime of the system, including upgrade safety, administrative controls, and operational guardrails that keep things safe as they evolve
• Build tooling and automated systems that let non-technical teammates safely view, monitor, and manage contracts without writing scripts or touching raw chain operations directly
• Connect smart contract design to the rest of the product, helping the web team integrate cleanly, helping operational teams monitor and manage without direct scripting, and ensuring design decisions flow through to end users
• Serve as tech lead and subject matter expert for blockchain projects, guiding the engineering team toward high-impact, scalable solutions and making sound technical decisions aligned with long-term goals

What you bring

• Location in PT, MT, CT, or ET time zones
• Excellent technical and non-technical communication skills, both verbal and written
• Bachelor's degree in Computer Science, Engineering, or a related technical field
• 5+ years of software engineering experience
• 3+ years in blockchain engineering, ideally from another DeFi protocol live on multiple chains
• Strong competency with Solidity
• Demonstrated ability to design systems, not just contracts, including tooling, automation, security across the contract lifecycle, and integration points between contracts, applications, and operational teams
• Proven results building and scaling a DeFi protocol
• Strong technical grasp and excellent judgment on task prioritization
• Strong emphasis on understanding the "why" behind requirements and a commitment to defining the "minimum scope"

Nice to have

• Exposure to non-EVM smart contract languages, particularly Solana
• Python and/or TypeScript experience for building tooling and automation

What we offer

• Competitive compensation including salary, future token rights, and/or equity according to your preferences
• Full benefits covering medical, vision, and dental, plus a flexible vacation policy (PTO)
• Small remote-first team across many countries, joining as an early member to help shape vision, culture, and design practices
• Colleagues from Goldman Sachs, Blackrock, Two Sigma, Bridgewater, SpaceX, AWS, Meta, Google, McKinsey, Circle, and Uniswap
• Backed by leading investors including Pantera Capital, Founders Fund, and Coinbase Ventures
