As Senior Backend Engineer you will own the systems that turn unstructured financial data into reliable, real-time insights our customers depend on every day. This role sits at the core of our product: the quality, speed, and reliability of what you ship directly determines whether finance leaders trust AI with their most critical work.

 * Ship backend services that enable AI agents to complete end-to-end analysis and reporting workflows 10x faster than manual processes within the first six months.

 * Own the reliability of data integrity and audit trails so every number our agents produce can be traced and trusted by CFOs and controllers.

 * Collaborate with product and AI teams to productionize new agent capabilities from prototype to customer-facing feature in under four weeks.
