You will be a hands-on backend engineer working in the IFD codebase to design, build, and support .NET-based services and batch components that implement decision logic and rules for CS and Trust partners.

Build and support APIs and integrations used by Help Hub, Agent Desktop, Seller Help, and other internal clients.
Drive code quality and safety via unit/integration tests, regression coverage, and code reviews.
Own observability and reliability (metrics, logs, alerts, dashboards) for the services you build and support.
Partner with product, operations, and policy teams to translate business requirements into scalable technical solutions.
What you'll bring:
Strong experience with C# and .NET building backend services, APIs, or batch systems.
Solid understanding of relational databases and SQL.
Experience working with distributed services (REST APIs, background workers, or similar) in production.
Demonstrated focus on testing, code quality, and maintainability.
Strong debugging and problem-solving skills in complex, integrated environments.
Effective communication and collaboration with cross-functional partners.
Preferred qualifications:
Experience with rules engines, decision tables, or decisioning platforms.
