At Ripple, we’re building a world where value moves like information does today. It’s big, it’s bold, and we’re already doing it. Through our crypto solutions for financial institutions, businesses, governments and developers, we are improving the global financial system and creating greater economic fairness and opportunity for more people, in more places around the world. And we get to do the best work of our career and grow our skills surrounded by colleagues who have our backs. If you’re ready to see your impact and unlock incredible career growth opportunities, join us, and build real world value. THE WORK: Ripple is building the Internet of Value: infrastructure that moves money as fast as information moves today. Every payment that flows across our network passes through real-time financial crimes controls: sanctions screening, wallet risk analysis, transaction monitoring, and travel rule compliance. The Financial Crimes Engineering team builds and operates that layer. This is the engineering that determines whether payments clear or hold, whether Ripple meets its regulatory obligations across jurisdictions, and whether the network can scale without compromising on compliance. The problem space is genuinely hard: high-throughput distributed systems, real-time decisioning, multi-source coordination across external compliance data providers, regulator-grade audit trails, and resilience. As a Senior Staff Software Engineer on this team, you will set the multi-year technical direction for the compliance control plane and drive its adoption beyond your own team. You will own the architecture of the vendor-agnostic, resilient, provable system that lets Ripple move value without moving financial crime, and you will shape how compliance engineering works across the company. This is a role for someone who defines which problems the organization solves, not only how they get solved: you will set the technical strategy other teams build against, establish the patt
