Job Req ID: 58791

Salary: Competitive
The Context Engineer is a specialist software engineering role focused on ensuring that AI systems receive the right information, in the right structure, at the right time to produce reliable, high‑quality outputs.
While similar in seniority to a Software Engineering Specialist, this role differs fundamentally in skillset and ways of working. Instead of writing application logic or services, the Context Engineer designs and engineers the context layer that powers AI agents—system prompts, tool definitions, memory strategies, and retrieval pipelines—across the software development lifecycle (SDLC).
This role is critical to making AI‑enabled delivery predictable, scalable, and safe.
