About the Role

The Agentic Engineering org at ServiceNow builds a conversational AI experience that turns enterprise intent into completed work. The Agent Orchestration team owns the execution core, including the agent harness, orchestration runtime, multi-agent coordination, memory management, and evaluation frameworks. Joining this team means being at the forefront of AI transformation, backed by ServiceNow's global scale and a high-growth environment.

Responsibilities

  • Design and build the agent execution harness, the orchestration layer that routes inputs, manages context, invokes tools, handles retries, and surfaces execution state across multi-step agentic workflows.
  • Own the runtime's fault tolerance, latency, and throughput; design for enterprise workflows that cannot fail silently or non-deterministically.
  • Instrument the harness with tracing, cost attribution, and latency visibility.
  • Build prompt management systems, including versioning, templating, and systematic evaluation.
  • Design and own evaluation frameworks (unit evals, integration evals, production monitors) that measure agent quality, catch regressions, and drive data-informed decisions.
  • Integrate with and abstract over frontier LLMs, managing model routing, fallback strategies, cost, and latency tradeoffs in production.
  • Raise the technical bar through architecture decisions, code reviews, and coaching, particularly on agentic design patterns and production AI discipline.
  • Define where agent logic lives and establish design standards across the team.

Requirements

  • 4+ years building production software systems with a strong track record on reliability, performance, and scalability.
  • Hands-on experience shipping generative AI products, owning AI-powered features that production users depend on.
  • Solid depth in how large language models work: failure modes, context constraints, and how prompt design shapes model behavior at scale.
  • Practical prompt engineering experience: systematically designing, versioning, and evaluating prompts across model updates or A/B evaluation cycles.
  • A real track record in eval engineering — a portfolio of evaluation suites designed, shipped, and used to drive quality decisions in production AI systems.
  • Cost and efficiency awareness at the system level: experience reasoning about model routing, inference cost, and latency tradeoffs in production.
  • Strong software engineering fundamentals: distributed systems, API design, and testing discipline.
  • Comfort operating in fast-moving, ambiguous, startup-like AI product environments.
