Job summary

ServiceNow seeks a Principal Engineer in HRSD to steer model-driven capability across HR domain, shaping AI architecture, agent behavior, and evaluation infrastructure that enables scalable, safe automation. You will define how reasoning happens, how context is assembled, and how tools are exposed, while ensuring human oversight for sensitive actions.

Collaborate with product and engineering to deliver robust, upgrade-safe AI solutions.

Qualifications

• 10+ years of software engineering with a track record of technical direction.
• Experience authoring agentic instructions and prompts, designing autonomous workflows, and building the evaluation that verifies them.
• Production experience with LLM APIs, retrieval-grounded features, agent orchestration, tool and function calling, and structured output enforcement — including at least one model or orchestration migration carried through production.
• Entitlement-aware data handling: per-user access enforcement in retrieval and tool layers, scoposeparation between roles, and handling of restricted records under audit.
• Evaluation experience used by engineers other than yourself: dataset curation, judge calibration, CI gating, drift detection.
• Strong command of system design, APIs, data modeling, and testing across front-end, server-side, and relational data work with ahigh qualitymindset.
• Effective, accountable use of AI coding assistants and agents.
• On-call and incident-command experience on customer-facing systems, including ownership of the systemic fixes that followed.
• Bachelor's degree in CS, software engineering, or a related technical field, or equivalent practical experience.

Responsibilities

• Own AI architecture for the HRSD domain.
• Decide as domain policy which HR actions an agent may take, which require a human decision point, and which no agent should attempt.
• Treat the surface as a versioned contract with upgrade-safe extension points and compatibility guarantees.
• Own the golden datasets, multi-turn suites, judge calibration, CI gates, and drift detection for safe behavior changes.
• Design diagnosis that works without exposing sensitive content in HR conversations.
• Define measurable standards for accountable agent-assisted delivery across the domain.
• Collaborate with product, engineering, and design to translate business needs into robust technical designs.
