Staff Software Engineer, Platform (DevEx)
Ready to be a Titan?
ServiceTitan is building the Developer Platform for enterprise-scale SaaS: a shared engineering ecosystem that powers seamless, high-velocity software delivery across our entire product footprint.
This is not a collection of script-runners. Our DevX platform is the runtime, framework, build, deployment, guardrail, and telemetry layer that lets hundreds of engineers ship code safely, observably, and at enterprise scale.
We are looking for a Staff Software Engineer to be the deepest technical voice on our DevX platform team. This is an individual-contributor role with outsized scope: you'll set technical direction, make architecture calls that other engineers build against, and personally ship the hardest, highest-leverage parts of the platform. You won't manage people, but you'll be expected to lead through influence — raising the technical bar for engineers and managers alike.
We need someone with deep production scars, strong systems intuition, and the judgment to know when to go deep on a gnarly problem versus when to unblock the team and move on. You should be comfortable being the technical backstop for a small, senior-heavy team and the person other engineers (and their managers) come to when something is architecturally ambiguous or on fire.
What You'll Build
You will be a primary technical owner across foundational DevX platform capabilities, including:
-
Environments: Cloud development environments (CDEs), on-demand provisioning, high-fidelity mocking, data seeding, and configuration management.
-
Build & CI/CD: Build parallelization, remote caching, automated test-splitting, secure pipelines, and zero-downtime progressive rollouts.
-
Developer Portal: A unified internal platform (IDP) providing "Golden Paths," automated service scaffolding, and centralized API/service catalogs.
-
Guardrails & Compliance: Automated linting, security scanning, policy-as-code injection, and static analysis embedded natively in workflows.
-
Velocity Harness: DORA metrics, build telemetry, local-to-production feedback loops, test flakiness analysis, and infrastructure cost tracking.
-
AI-Native Tooling: AI-assisted development tooling and coding agent runtimes (e.g., Codex-style agents) that help engineering teams operate at "AI speed" — including the platform primitives (sandboxing, context/data access, evaluation harnesses) that make agentic coding safe at scale.
What You'll Do
-
Set technical direction for the platform: define architecture, platform contracts (service templates, environment configs, pipeline steps, deployment manifests), and long-term design tradeoffs.
-
Personally design and build the highest-leverage, highest-ambiguity pieces of the platform — the parts too risky or too foundational to hand off.
-
Review designs and code across the team; be the escalation point when a technical decision needs a final call.
-
Debug the hardest production issues in the platform: pipeline failures, build system regressions, infrastructure drift, flaky test root causes.
-
Partner directly with Product, Security, SRE, and domain engineering leads to align the platform roadmap with real usage patterns and constraints.
-
Mentor and level up engineers and EMs on the team through code review, design review, and pairing — without formal management authority.
-
Translate ambiguous, org-wide DevX strategy into a concrete technical roadmap that others can execute against.
-
Represent the platform in cross-functional architecture reviews and act as a technical reference for teams building on top of it.
-
Own the technical design of AI-assisted developer tooling and coding agent runtime infrastructure — evaluating, integrating, and hardening agentic coding tools for production use across R&D.
What You'll Bring
-
10-15+ years of software engineering experience, with a track record of technical leadership on platform, infrastructure, or DevX systems at scale.

Deep, current hands-on
