Llm Prompt Evaluation Jobs (NOW HIRING)

The Context Engineering & LLM Optimization Principal Engineer is responsible for defining and leading the engineering approach for solutions at the program or portfolio level, to deliver significant business outcomes. Key responsibilities include continuously improving the design, quality, and reuse of the solution and delivering technology enablers that improve development efficiencies for the solution. Job expectations include familiarity with at least one area of engineering, acting as a “go to” reference across the organization, and applying knowledge to improve technical competencies through recruitment and development activities.

Developer Experience (DevEx) provides enterprise technical standards and common technical services, platforms, and tools that are leveraged by delivery teams across all lines of business. Within the SDLC Software Delivery Lifecycle program, this role leads portfolio product delivery strategy and execution for enterprise software delivery capabilities, ensuring the right investments, operating model, governance, and prioritization are in place to improve how internal technical users build, test, and deliver software at scale.

The Context Engineering & LLM Optimization Principal Engineer is responsible for designing how information is selected, organized, compressed, prioritized, and presented to LLMs. This role focuses on context window management, prompt architecture, retrieval orchestration, grounding strategies, instruction design, tool‑use patterns, and evaluation of LLM behavior.

This engineer ensures that LLM applications receive the right context, in the right format, at the right time, with minimal token waste and maximum answer quality.
