About Us We are a on a mission to rebuild how financial services firms create, manage, and execute their data integrations and transformations. Today that process stretches across multiple teams, tools, and handoffs - slow to build, expensive to maintain, and nearly impossible to change. We collapse it into a single AI-native platform that business users can operate without writing a ticket, while engineering teams retain the governance and security controls they require. We're growing our founding team now. About the Role As our QA Engineer, you'll own the quality layer for a platform where data correctness is non-negotiable. Our product processes financial data integrations and transformations on behalf of enterprise customers - errors in transformation logic, silent pipeline failures, or API regressions have real downstream consequences for real financial operations.
