Résumé du poste

ServiceTitan is hiring an AI Engineer (California onsite) to build core engineering primitives for the Agent OS platform, delivering reliable runtimes, governance, and platform services for automated agent workflows.

You will collaborate with product teams to package prompts, tools, context requirements, policies, and evaluation methods, while ensuring scalable, auditable operations across financial, contractual, and compliance-sensitive processes.

Responsabilités

• Build the runtime for role-specific agents, including tool use, delegation, pause/resume, durable checkpoints, retries, and failure recovery.
• Create deterministic controls around non-deterministic reasoning, including governed reads, proposed writes, precondition checks, business invariants, scoped permissions, idempotency, audit trails, and rollback.
• Develop tenant-scoped context assembly with retrieval, freshness controls, provenance, transcripts, artifacts, tool results, and replayable evidence.
• Implement human‑in‑the‑loop gates with approval thresholds, reversibility, tenant policy enforcement, and audit history for financial, contractual, dispatch, warranty, and compliance‑sensitive workflows.
• Build offline and online evaluation systems, including scenario libraries, simulation, trajectory review, regression detection, and cost and latency telemetry with autonomy promotion gates.
• Help product teams package prompts, tools, context requirements, policies, evals, rollout controls, ownership, and rollback into governed capabilities for owners, CSRs, dispatchers, technicians, managers, and back‑office teams.
• Make practical tradeoffs across latency, cost, quality, structured outputs, caching, fallback behavior, provider choice, and model routing behind a shared platform layer.
• Design and implement core Agent OS platform services.
• Write production code and review implementation details from other engineers.
• Build reliable APIs, workflows, tools, and services for agent execution.
• Inspect traces, debug failures, and improve production behavior.
• Design evaluation scenarios and regression suites for agent workflows.
• Work through real agent failure modes, including stale context, wrong tool calls, missing permissions, unsafe actions, poor retrieval, latency spikes, and cost regressions.
• Partner with domain teams to turn agent use cases into reusable platform patterns.
• Help define platform contracts for tools, actions, approvals, context, memory, evidence, and evaluation.
• Contribute to technical direction while staying grounded in what can ship quickly and safely.
• Communicate clearly with engineers, product managers, architects, security partners, and engineering leadership.
