Full-Stack Java Developer — open source & AI-assisted delivery
Senior full-stack Java engineers who build modern, API-driven applications, contribute to open-source software, and use AI development harnesses to accelerate delivery — proficiencies that map directly to building AI business applications on our platform.
Responsibilities
•     Design, build, and maintain full-stack Java applications (backend services and web front-ends) on a cloud-based middleware platform.
•     Integrate large language models, retrieval-augmented generation (RAG), and vector data stores into application features.
•     Use AI development harnesses and agentic coding tools to prototype and ship solutions faster.
•     Contribute high-quality, well-tested code; participate in code review and uphold engineering standards.
•     Work within a secure, government cloud environment and iterate as platform requirements evolve.
Required skills
•     Strong full-stack Java (e.g., Spring / Spring Boot) plus a modern JavaScript front-end framework (React or Angular).
•     Demonstrable open-source contributions — public repositories and merged pull requests to established projects.
•     Hands-on experience using AI / LLM development harnesses or agentic coding tools to build software.
•     API and service integration; solid SQL and data-handling skills.
•     Ability to learn an unfamiliar platform / middleware stack quickly.
•     US work authorization; clearance eligibility per contract environment.
Preferred
•     GenAI application experience: embeddings, RAG, and vector databases (pgvector, ChromaDB, Pinecone, or similar).
•     Cloud (AWS or Azure) and containerization (Docker / Kubernetes).
•     Prior federal or regulated-environment delivery.
