Principal Engineer - Agentic AI Framework and Harness

Job Description

This job 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 (Dev Ex) 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.

We are seeking a highly accomplished Agentic AI Framework & Harness Principal Engineer to define and drive the architecture, engineering standards, and technical roadmap for reusable agent frameworks and harness capabilities embedded across the Software Delivery Lifecycle (SDLC). This role will shape how engineering teams design, compose, test, and operationalize agentic workflows through robust framework abstractions, deterministic execution patterns, and enterprise‑grade developer tooling.

This role requires deep technical leadership in agent orchestration, memory patterns, policy hooks, tool calling, planning loops, simulator harnesses, deterministic workflow design, eval integration, and SDK, API, and CLI design. The ideal candidate brings strong hands‑on engineering depth, platform design expertise, and a track record of building reusable framework capabilities that improve correctness, composability, governance, testability, and developer productivity for agentic systems in production.

• Develop the engineering approach for the entire program/portfolio solution and work with Architecture to develop, analyze, and deliver the implementation of technical enablers.
• Lead the planning, definition, and design of complex features which span multiple teams and explore solution alternatives.
• Create ideas on designing complex technology and solution development approaches.
• Provide technical oversight for teams in solution development, including design reviews and code within own domain.
• Define the technology tool stack for the solution within the range of internally approved and supported technologies.
• Explore state‑of‑the‑art technologies to improve development efficiencies, quality of test/QA coverage, and release management.
• Lead and be responsible for the end‑to‑end test strategy/creation/adherence, and the integration between teams for a program/portfolio solution.
• Improve the experience for our developers, making it easier to deliver industry‑leading solutions, while managing work efficiently and with the right controls.
• Advance our technology platforms through innovation.
• Reduce risk and improve quality across our technology portfolio by aligning to a single enterprise architecture strategy and delivering governance that enables consistency, integration and automation.

• 15+ years of engineering experience with deep technical leadership in enterprise software platforms, developer tooling, or AI‑enabled engineering systems.
• Demonstrated ownership of architecture, standards, and engineering direction for shared platforms used across multiple delivery teams or lines of business.
• Experience engineering solutions in highly regulated environments with strong SDLC, risk, audit, and control requirements.
• Ability to influence senior technology leaders, platform teams, and risk partners through clear technical strategy,…
