We are looking for a Senior Full-Stack Engineer to join a three-person team at a leading financial institution. The project replaces a legacy system of 16 workflows: a web portal where branch users submit requests, and a backend that sends them to other systems, receives responses, updates statuses and manages approvals. Delivery dates are aggressive, so we need someone who can contribute quickly after onboarding.

• Design and build backend services in C# / .NET, applying clean architecture and engineering best practices.
• Deliver features end to end: APIs, integrations with other systems, approval-workflow logic and the React web portal.
• Work in an Agile team with two-week sprints and the usual ceremonies.
• Answer teammates' technical questions and take part in code reviews.
• Write and maintain unit and regression tests.
• Document technical decisions and collaborate with business stakeholders and teams that own other systems.

5+ years of hands-on software development experience in C# / .NET (7+ preferred), building applications rather than only maintaining them. Applied
