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.

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 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.
