About this role
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. This role also integrates agentic AI workflows into the application stack, orchestrating existing AI/LLM services rather than training or fine-tuning models. Candidates should expect to move fluidly across the full stack on any given day, not specialize in a single layer. Frontend Development (Angular) • Design and build responsive, maintainable Angular applications and components, including state management, routing, and reusable component libraries. • Consume and integrate REST APIs into the UI, handling loading states, error handling, and data validation. • 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. API & Backend Development (.NET) • 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. • Architect and implement integration layers connecting Python-based agentic services with .NET applications (via APIs, message queues, or SDKs). • Apply solid software design principles (SOLID, dependency injection, clean architecture) to keep backend services maintainable and testable. • Ensure secure, scalable, and maintainable integration patterns across all application layers. Database Engineering (SQL Server) • Design, optimize, and maintain SQL Server databases supporting transactional application data and agentic workflow data (logging, agent state, audit trails, metadata). • Write and tune complex stored procedures, queries, indexes, and ETL processes for both application and agentic workflow needs. • Own data model design decisions in partnership with backend and API development. Testing & Quality Assurance • Build and maintain automated test suites using Playwright for UI and end-to-end testing across the full application stack. • Write unit and integration tests for .NET services and APIs as part of the standard development workflow, not as a separate hand-off. • Develop testing strategies specific to agentic systems (prompt regression testing, output validation, agent behavior testing, edge-case/adversarial testing). • Participate in code reviews, CI/CD pipeline maintenance, and release quality gates. Agentic AI Integration • Integrate with third-party or internally hosted AI/LLM APIs (e.g., OpenAI, Anthropic Claude, Azure OpenAI, Bedrock, Vertex AI) to power agentic capabilities within applications. • Write Python-based scripts/services for agent orchestration using frameworks such as LangChain, LangGraph, AutoGen, Semantic Kernel, or similar, and wire them into the .NET/Angular application stack. Cloud & Infrastructure • Deploy, monitor, and manage application services and supporting infrastructure on AWS and/or GCP (e.g., Lambda/Cloud Functions, container services, storage, IAM). • Collaborate with DevOps to ensure scalable, cost-efficient, and secure cloud deployments across the full stack.
