We are seeking an experienced, true full stack Developer/Tester who can own an application end to end: Angular front-end, .NET API and backend services, SQL Server data layer, and automated testing. The ideal candidate is equally comfortable building a UI component, designing an API contract, writing a performant stored procedure, and authoring the test suite that validates all three.

Responsibilities

Design and build responsive, maintainable Angular applications and components, including state management, routing, and reusable component libraries.
Build UI components that surface agentic AI features (chat interfaces, recommendation panels, agent status/monitoring dashboards, etc.) within existing or new applications.
Collaborate with design/UX to translate requirements into polished, accessible interfaces.
Design and develop backend services and APIs in .NET (C#), following REST/gRPC best practices for consumption by the Angular front-end and downstream systems.
Design, optimize, and maintain SQL Server databases supporting transactional application data and agentic workflow data (logging, agent state, audit trails, metadata).
Own data model design decisions in partnership with backend and API development.
Build and maintain automated test suites using Playwright for UI and end-to-end testing across the full application stack.
Develop testing strategies specific to agentic systems (prompt regression testing, output validation, agent behavior testing, edge-case/adversarial testing).
Collaborate with DevOps to ensure scalable, cost-efficient, and secure cloud deployments across the full stack.
