## About the Role

* 3+ years of non-internship professional software development experience
 * Experience building production web applications with TypeScript and a modern React framework (React/Next.js)
 * Experience building and operating backend services or APIs (e.g., FastAPI, Node) that a frontend consumes
 * Experience with real-time or streaming interfaces (Server-Sent Events, WebSockets, or equivalent), including handling reconnection and out-of-order events
 * Experience with automated testing at the unit and end-to-end level (e.g., jest, Playwright) as part of the definition of done
 * Experience diagnosing defects across the stack - from a client-side symptom to the backend route or payload that caused it - using logs and traces as evidence, * Experience building interfaces for AI/agentic or other long-running, streaming systems (token-by-token output, tool-call visualization, document classification result rendering, run/trace inspection)
 * Experience with GenAI/LLM integration: prompt engineering workflows, model evaluation dashboards, fine-tuning pipeline UIs
 * Experience deploying applications in AWS GovCloud or classified (IL5/IL6) environments
 * Experience integrating with DoD identity providers and CAC/PIV authentication
 * Experience with client and server state management and optimistic-update patterns
 * Proficiency using AI coding assistants as a daily driver, with the judgment to verify their output against tests and traces before merging

 * Experience with AWS services: Amazon Bedrock, S3, Lambda, Step Functions, CDK
 * Bachelor's degree in Computer Science or equivalent practical experience

## Description

The candidate will own the human-in-the-loop surface of the GenAI IDP platform end to end: the React/Next.js UI and the backing API/BFF services that feed it. This is a streaming, stateful window into live agent execution supporting DCSA document processing workflows - not generic web development. The engineer owns the vertical slice from React component through the SSE event pipeline to the backend route that serves it - durable chat state, notification architecture, tool-call and artifact visualization, document classification results rendering, and trace exploration.
