Staff Software Engineer, Platform (DevEx)

Overview

Staff Software Engineer on the newly formed Developer Experience (DevEx) team, building AI-enabled platform infrastructure, including AI-assisted development tools and coding agent runtimes, to help engineering teams operate at AI speed.

What you'll do

• Build components of the agent orchestration layer and harness that let coding agents operate reliably inside ServiceTitan's systems.
• Build environment tooling covering CDEs, on-demand provisioning, mocking, and data seeding.
• Build CI/CD pipelines including build parallelization, remote caching, test-splitting, and secure, progressive rollout.
• Build the Developer Portal, including Golden Paths, scaffolding, and service/API catalogs.
• Build guardrails and compliance into workflows, including automated linting, security scanning, and policy-as-code.
• 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 infrastructure, environments) and glue distributed systems together.
• Write code and set the standard others emulate, with 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.
• Make technical decisions across a large area of the platform and resolve in-depth needs independently.
• Be the go-to subject-matter expert for at least one major piece of the DevEx platform, such as the agent harness or the CDE provisioning layer.
• Mentor engineers in technical design and architecture; participate in interviewing and hiring recommendations.
• Partner with the Principal Engineer/EM to turn multi-quarter strategy into sequenced, shippable slices of infrastructure.

What you'll need

• 10+ years of software engineering experience.
• 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.
• A primary dev environment built around a coding-agent app (e.g., Codex, Claude Code) that you run on both desktop and mobile.
• Agent sessions you keep running continuously rather than one-off.
• Ability to speak in depth about orchestrating more than one agent against real work, not just occasional prompt engineering or drafting specs from a brief.
• Experience shipping CI/CD pipelines, build systems, internal developer portals, or test automation platforms in production, at a scope consistent with large, potentially distributed systems.
• Practical fluency with containerization/orchestration (Kubernetes/Docker) and cloud infrastructure (AWS/GCP).
• Comfort operating independently on a small team, planning around disruptions.

Nice to have

• Some direct exposure to coding-agent-runtime work, even partial.
• Experience where AI-agent adoption was a team or org push you helped drive, with work that is current (roughly the last 3 months).
• Experience with compliance-sensitive workflows, change management systems, or policy engines.
