Note: The job is a remote job and is open to candidates in USA. ServiceTitan is building an enterprise-scale developer platform and a lean DevEx team focused on AI-enabled platform infrastructure. The Principal Software Engineer will set technical direction for AI-native developer tooling, design and deliver complex systems, advise multiple teams on agent-runtime architecture, and mentor engineers.
Responsibilities
- Proactively identify where your expertise on coding-agent infrastructure could help teams across R&D, not just within DevEx — and contribute to the wider industry conversation on agent-runtime architecture
- Deliver complete, comprehensive system designs and lead autonomous delivery of the projects that come from them, in partnership with R&D peers. Remove barriers that are widely felt across the engineering org, not just your pod
- Operate self-directed and unsupervised. Act as the key technical consultant on agent-runtime architecture across multiple teams; your judgment and timeliness on hard calls is what people rely on
- Anticipate technical problems before they surface in major platform initiatives; identify ServiceTitan's technology needs on a 1–3 year horizon for AI-native developer tooling and drive the milestones to get there
- Your work (harness code, orchestration patterns, agent-safety guardrails) becomes the thing other engineers copy to hit the quality bar you've set
- Mentor and raise the technical bar for engineers at Staff level and below on the team
Skills
- • 10+ years of software engineering experience, with recent (last 6–12 months) hands-on work building coding-agent-runtime infrastructure — agent orchestration, harnesses, or LLM reasoning loops. This is a hard filter: process automation or AI-assisted code review experience does not meet this bar
- • A track record consistent with Principal-level scope: technical decisions and architecture that other teams and orgs build on, not just your own team's roadmap
- • Deep experience with build systems, CI/CD, or internal developer platforms shipped and operated in production at real scale
- • Comfort setting direction with minimal oversight — this is a small, high-trust team; you're expected to define the plan, not receive it
- • Strong instincts for environment safety (RBAC, secrets management, compliance gates) as applied to autonomous or semi-autonomous coding agents specifically
- • Prior experience where coding agents are already core to daily engineering workflow, not a pilot
- • Experience representing engineering direction externally (blog posts, conference talks) or influencing practice change across an org
