Navitas is seeking a Full Stack Python Developer to build and scale user-facing and backend applications that power AI/ML capabilities for the DoD Search Portfolio. You will develop secure, cloud-native web services and UI experiences that integrate with LLM/RAG and semantic search pipelines. This role partners closely with ML engineers and data teams to product ionize models through robust APIs, workflows, and operational tooling.

You will help deliver mission-ready solutions that handle large-scale datasets with strong performance, reliability, and traceability. The ideal candidate thrives in fast-paced environments and enjoys building end-to-end systems that make AI usable for real users.

• Support CI/CD and Dev Ops practices (containerization, deployment automation, monitoring/alerting) to ensure stable releases and operational readiness.
• Apply best practices for security, logging, auditing, and compliance aligned with federal/DoD standards across services and environments.
• Design and develop Python backend services and REST APIs (e.g., Flask/FastAPI) to expose AI/ML and search capabilities to applications and mission systems.
• Build full stack features (UI + API) that support search workflows, semantic retrieval, and results visualization for enterprise users.
• Integrate backend services with Databricks/Spark pipelines and ML workflows to enable scalable inference, data processing, and batch/stream execution.
• Implement and maintain integrations with Elasticsearch (search/indexing) and Neo4j (graph/relationship-driven experiences) to enhance relevance and discovery.
• Collaborate with ML Engineers to product ionize LLM/RAG-based features, including prompt/inference orchestration, embeddings services, and retrieval workflows.
• Create clear technical documentation and communicate design decisions, trade-offs, and implementation approaches to both technical and non-technical stakeholders.

• Bachelor’s degree (or equivalent experience) with 5+ years in software engineering focused on Python and web application development.
• Strong hands‑on experience building Python APIs/services (Flask/FastAPI preferred) and integrating with databases, search platforms, and external systems.
• Experience developing full stack applications using modern front‑end frameworks (React/Angular/Vue) plus strong API design skills.
• Familiarity with AI/ML concepts and integrations (LLMs, embeddings, semantic search, RAG workflows) and working closely with data/ML teams.
• Working experience with cloud‑native delivery (Docker/Kubernetes), CI/CD, Git-based workflows, and performance/reliability best practices;
  Databricks/Spark experience required.
