📋 Description

• Senior AI Engineer building the Agent OS platform that powers production-grade AI agents across ServiceTitan’s product surfaces, enabling contractors to run their businesses with safe, observable, and trustworthy agent workflows.
• Design and implement core platform services including agent runtime, typed tools, context and memory systems, trust and approval infrastructure, evaluation and observability, and reusable capability platforms for agent execution.
• Work on a small, senior AI platform team collaborating with Product, Architecture, Security, Data Platform, Atlas, and domain engineering teams to turn agent use cases into governed, reusable platform patterns.
• Contribute to technical direction while ensuring systems are production-safe, scalable, and aligned with multi-tenant SaaS constraints, helping set the standard for all future AI surfaces at ServiceTitan.

🎯 Requirements

• Practical understanding of modern LLM application architecture including model gateways, prompt and context assembly, retrieval, tool calling, structured outputs, memory, agent workflows, and human approval patterns.

• Strong production-safety instincts for non-deterministic systems: typed contracts, scoped permissions, precondition checks, idempotency, audit trails, rollback, and monitoring.
• Experience designing or operating evaluation systems: behavioral evals, regression suites, scenario tests, trajectory review, simulation, online metrics, or production monitoring.

🏖️ Benefits

• Flextime, recognition, and support for autonomous work including flexible time off, learning and development opportunities, leadership training, and rewards via Bonusly and peer-nominated awards.
• Holistic health and wellness benefits: company-paid medical, dental, and vision (with 100% employer-paid options and 90% coverage for dependents), FSA and HSA, 401k match, and telehealth including One Medical membership.
• Support for Titans at all stages of life: parental leave, up to $20k in fertility services (IUI/IVF), surrogacy and adoption reimbursement, maternity support via Maven Maternity, free breast milk shipping via Maven Milk, pet insurance, legal advisory, financial planning tools, and more.
