Senior Software Engineer, Backend - Platform...

• Contribute to the core platform: the detection engine, invariant framework, and tooling that partner teams use to onboard their fund flows.

• Own workstreams end-to-end: from designing correctness models with partner teams to operating them in production.

• Build AI guardrails that close the velocity gap: predictive consistency models that flag deviations at initiation (not after settlement), and proactive invariant discovery that surfaces coverage gaps before any team asks - before incidents, not because of them.

• Mentor junior engineers and lead technical execution on high-impact projects.

• 5+ years of software development experience with large-scale distributed systems.

• Strong sense of correctness - not just "does the code work" but "is the system as a whole behaving correctly."

• Experience building platform-level infrastructure used by multiple teams.

• Strong ownership: you hold the problem, not just the ticket.

• Demonstrates the ability to responsibly use generative AI tools and copilots (e.g., LibreChat, Gemini, Glean) in daily workflows, continuously learn as tools evolve, and apply human-in-the-loop practices to deliver business-ready outputs and drive measurable improvements in efficiency, cost, and quality.

Nice to haves:

• You have gone through a rapid growth in your company (from startup to mid-size).

• Experience with financial, payments, or reconciliation systems.

• Streaming data infrastructure (Kafka, Flink, Spark, or similar).

• You've worked with Golang, Ruby, Docker, Postgres, MongoDB or DynamoDB.

• You've built financial, high reliability or security systems.

• Crypto-forward experience, including familiarity with onchain activity such as interacting with Ethereum addresses, using ENS, and engaging with dApps or blockchain-based services.

At Coinbase, our mission is to increase economic freedom in the world. It's a massive, ambitious opportunity that demands the best of us, every day, as we build the emerging onchain platform - and with it, the future global financial system. To achieve our mission, we're seeking a very specific candidate. We want someone who is passionate about our mission and who believes in the power of crypto and blockchain technology to update the financial system. We want someone who is eager to leave their mark on the world, who relishes the pressure and privilege of working with high caliber colleagues, and who actively seeks feedback to keep leveling up. We want someone who will run towards, not away from, solving the company's hardest problems. Our [work culture](https://www.coinbase.com/mission) is intense and isn't for everyone. But if you want to build the future alongside others who excel in their disciplines and expect the same from you, there's no better place to be. While many roles at Coinbase are remote-first, we are not remote-only. In-person participation is required throughout the year. Team and company-wide offsites are held multiple times annually to foster collaboration, connection, and alignment. Attendance is expected and fully supported. The Overseer team is Coinbase's business integrity layer. We make the financial contracts between Coinbase's systems explicit - the rules that must always hold across every fund flow - and detect violations in real time. When something breaks, we know within seconds, not in the quarterly reconciliation. We work with every team at Coinbase that moves money.
