# Senior AI Platform Engineer Contract

Nextdata is looking for an experienced AI Platform Engineer for an initial three-month project focused on building and validating an AI-enabled data platform capability. This is a hands-on implementation role. You will quickly ramp up on an existing project and build backend services, agent tools, APIs, and data integrations. The role has no customer-facing responsibilities and less emphasis on architecture than a principal-level position. If successful, the project may continue and develop into a broader Nextdata product. What You’ll Do Quickly understand the existing codebase, requirements, and technical direction. Build backend services, AI agents, tools, and APIs for governed data access. Implement MCP-compatible endpoints or similar agent interfaces. Integrate SQL, documents, APIs, metadata, semantic models, and vector search. Build retrieval, tool selection, context construction, and grounded response flows. Add access controls, policy enforcement, audit logging, tests, and observability. Deliver a reliable, documented system within the three-month project scope. What We’re Looking For Strong experience with backend systems, data platforms, or distributed systems. Pra
