Full-Stack Java Developer — open source & AI-assisted delivery

Email: talent@neevsys.com Job Description Neevsys is currently seeking two 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.
