Staff Product Engineer

About the role

You will own the end-to-end delivery of complex financial features, shaping both the user interface and the underlying services that power them. You will set the technical direction for the Product Engineering team, making high-impact architecture decisions that define the broader product surface. You will partner closely with Product and Design to own roadmap decisions, translating business goals into polished user experiences and robust backend systems. You will mentor engineers, drive code quality, and establish patterns that raise the bar for how the team ships. You will use deep product expertise to reason about edge cases and ensure the user experience remains intuitive even when data is incomplete or unexpected. You will lead cross-functional initiatives, aligning Engineering, Product, and Data Science on priorities and tradeoffs. You will improve how the team works by refining processes and establishing abstractions that make the product surface easier to develop and maintain. You will take ownership of APIs, data models, and backend services, ensuring performance, reliability, and consistency across the stack.
