Full Stack Developer/Tester

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.
