Staff Software Engineer

About the Job

Ready to be a Titan? ServiceTitan is building the Developer Platform for enterprise-scale SaaS. DevEx is a newly formed, lean, highly agile team (3–4 people) building AI-enabled platform infrastructure — pioneering AI-assisted development tools and coding agent runtimes (like Codex) to help engineering teams operate at "AI speed."

This Role

This is a Staff Software Engineer role per ServiceTitan's engineering leveling framework: 10+ years of experience, Advanced Engineer level, working across squad(s)-scale, large or potentially distributed systems.

What You'll Build

• AI-Native Tooling: Components of the agent orchestration layer and harness that let coding agents operate reliably inside ServiceTitan's systems.
  Environments: CDEs, on-demand provisioning, mocking, and data seeding.
• Build & CI/CD: Build parallelization, remote caching, test-splitting, secure and progressive rollout pipelines.
• Developer Portal: Golden Paths, scaffolding, and service/API catalogs.
  Guardrails & Compliance: Automated linting, security scanning, and policy-as-code embedded in workflows.

Nature of Work

• Make core architectural decisions and design systems within your area
  Lead investigations and guide deep-level refactoring
  Demonstrate knowledge across multiple domains (agent runtimes, build infra, environments) and know how to glue distributed systems together.

Delivery

Write code and set the standard others emulate — full rigor on testing for scale, resiliency, performance, and security. Roadmap large tracks of work with reliable estimates and help the team hit its commitments.

Independence & Decision Making

• Make technical decisions across a large area of the platform
  Resolve in-depth needs without needing to be told how.

Ownership

Be the go-to SME for at least one major piece of the DevEx platform (e.g., the agent harness, or the CDE provisioning layer) — recognized by the team as the person who owns it.
