Summary
What you’ll impact
The Principal Engineer, Developer Infrastructure defines and drives the technical roadmap for build, test, and platform tooling across multiple engineering teams. The role utilizes Bazel monorepo builds, remote execution clusters, CI/CD pipelines, Kubernetes, AWS, and languages such as Go, Python, and TypeScript. Responsibilities include scaling CI/CD to thousands of daily builds, advancing test environments, and integrating AI‑powered automation and intelligent code review throughout the development lifecycle. Collaboration with leadership sets technical standards, while mentoring senior engineers raises overall productivity.
Responsibilities
What you'll do
- Own the technical direction and roadmap for the Developer Infrastructure org — serving as the lead across DevX, TestX, Backend Platform, and Mobile Platform, unifying four engineering teams under a shared technical vision
- Lead and evolve the organization's Bazel-based monorepo build infrastructure — own the remote build execution cluster, drive language-agnostic build optimization across Python, Go, TypeScript, and more, and ensure fast, stable feedback loops for the entire engineering org
- Scale CI/CD pipelines to support thousands of daily builds with speed, safety, and reliability — overseeing GitHub repository configurations, pre-merge checks, and test execution infrastructure across the organization
- Drive the vision for TestX — the test infrastructure and environments that power the organization's entire test experience, including integration test environments and personal development environments that simulate the full system so engineers can test safely and confidently
- Champion the integration of AI and agentic systems across the full software development lifecycle — driving initiatives that use intelligent automation and coding agents to multiply developer velocity, improve code quality, and accelerate the pace of innovation across the org
- Set technical standards across Backend Platform and Mobile Platform — owning the vision for core language runtimes, libraries, IDE tooling, and developer environment security across Python, Go, TypeScript, Swift, and Android
- Partner with engineering leadership and cross-functional stakeholders to define and execute a long-term developer infrastructure roadmap that embeds AI as a force multiplier at every layer of the SDLC
Requirements
What you’ll bring
- 10+ years of software engineering experience with a demonstrated track record at the Senior Staff, Principal, or Distinguished Engineer level — you've set technical direction at the org or company level, not just the team level
- Deep expertise with Bazel and large-scale monorepo build systems — you've owned remote build execution infrastructure at scale and understand the architectural tradeoffs deeply
- Experience building and operating CI/CD pipelines at massive scale — across thousands of daily builds, multiple programming languages, and complex pre-merge pipeline logic
- Fluency in Go and/or Python; broad familiarity with TypeScript, Swift, or Android development environments is a strong signal
- Strong background with distributed systems, Kubernetes, and cloud infrastructure (AWS preferred) — you understand the full stack of developer tooling from IDE to deployment
- Experience with test infrastructure, integration test environments, or developer environment platforms — you understand what a great test experience looks at scale
- Genuine interest in or hands-on experience with agentic AI systems, automated code review, or AI-driven developer velocity programs — you have a clear point of view on how AI will reshape the software development lifecycle and want to be the one building it
- Exceptional technical leadership, communication, and influence skills — you've unified cross-functional engineering teams around a shared vision and driven ambiguous, org-spanning initiatives to completion
- Track record of mentoring senior engineers and elevating the technical bar across large, diverse engineering organizations
