[Hiring] Staff Software Engineer, Platform @ServiceTitan

Role Description

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 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.

What You'll Do

• 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 and 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.
• Leadership: Mentor engineers in technical design and architecture; participate in interviewing and hiring recommendations for the team. Partner with the Principal Engineer/EM to turn multi-quarter strategy into sequenced, shippable slices of infrastructure.

Qualifications

• 10+ years of software engineering experience, with recent (last 6–12 months) hands-on platform or DevX work.
• Direct, hands-on experience with AI/agent tooling beyond process automation or code-review assistance.
• Experience shipping CI/CD pipelines, build systems, internal developer portals, or test automation platforms in production.
• Practical fluency with containerization/orchestration (Kubernetes/Docker) and cloud infrastructure (AWS/GCP).
• Comfort operating independently on a small team.

Preferred Experience

• Some direct exposure to coding-agent-runtime work.
• Experience where AI-agent adoption was a team or org push you helped drive.
• Experience with compliance-sensitive workflows, change management systems, or policy engines.

Benefits

• Flextime, recognition, and support for autonomous work: Flexible time off with ample learning and development opportunities.
• Holistic health and wellness benefits: Company-paid medical, dental, and vision, FSA and HSA, 401k match, and telehealth options.
• Support for Titans at all stages of life: Parental leave, fertility services, surrogacy, and adoption reimbursement.
