Concretely, we're looking for: 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, and the ability to speak in depth about orchestrating more than one agent against real work - not just occasional prompt engineering or asking an agent to draft a spec 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 - you're expected to see and plan around disruptions, not just react to them. ## Description * 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., * Some direct exposure to coding-agent-runtime work, even partial - the strongest differentiator against other Staff-level platform candidates. * Experience where AI-agent adoption was a team or org push you helped drive, not just something you did solo - and where the work is current (roughly the last 3 months), not a project you haven't touched in over a year. * Experience with compliance-sensitive workflows, change management systems, or policy engines. Be Human With Us: Being human isn't about checking every box on a list. It's about the experiences we have, people we meet, and the perspectives we share. So, if you have the skills but are hesitant to apply because of your background, apply anyway. We need amazing people like you to help us challenge the conventional and think differently about the problems that we're solving. We're in this together. Come be human, with us. Use of AI Technology: We use technology, including automated and AI-assisted tools, to support certain aspects of our recruitment process. These tools are designed to improve efficiency and enhance the candidate experience. AI tools are not used to make hiring decisions; all hiring decisions are made by our hiring teams.
