## 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 distributed tracing (OpenTelemetry) from the application side
Experience with AWS services: Amazon Bedrock, S3, Lambda, Step Functions, CDK
Bachelor's degree in Computer Science or equivalent practical experience

Program Qualification
Run an engineering practice driven by evaluation, testing, and verification - changes are proven with tests, traces, and metrics before they are called done
Operate agentic systems fluently (MCP tools, Bedrock/LLM calls, streaming, distributed traces) in support of GenAI IDP document classification and field extraction workflows
Work within DCSA classified environments (IL5/IL6) following DoD security baselines and STIG compliance requirements
Support the GenAI IDP solution: prompt engineering, model fine-tuning, evaluation logic for document section classification and extracted field validation
Use AI coding assistants heavily as daily drivers, while remaining skeptical of their output and holding it to the same evidentiary bar as any other code
Current, active Top Secret clearance
Current, active Security+ or equivalent certificate for privileged user access
