How to Apply for Staff Site Reliability Engineer

at Zoox

🏢 About Zoox

Zoox is pioneering fully autonomous electric vehicles designed from the ground up for urban mobility, aiming to reduce congestion and carbon emissions. As a remote-friendly company with a mission-driven culture, Zoox offers a unique opportunity to shape the future of transportation while working on cutting-edge infrastructure challenges.

About This Role

This Staff SRE role owns the technical strategy for source control at Zoox, including a high-impact migration from GitHub Enterprise to GitHub Cloud. You'll build and scale a monorepo for hundreds of engineers, reducing developer toil through tooling and guardrails—directly impacting build times and merge friction.

💡 A Day in the Life

A typical day might start with reviewing design proposals for monorepo improvements, then pair programming with an engineer on a CI pipeline optimization. After lunch, you'll analyze build time metrics and merge friction data, followed by a cross-team sync to align on the GitHub Cloud migration roadmap.

🎯 Who Zoox Is Looking For

  • Has 5+ years operating GitHub Enterprise at scale, with hands-on monorepo management for 300+ engineers and experience with large-file handling, branch strategies, and code ownership.
  • Deeply understands CI/CD integration (Buildkite, GitHub Actions, or similar) and can optimize build triggers, merge automation, and branch policies.
  • Proficient in infrastructure as code (Terraform, Pulumi) and cloud platforms (AWS, GCP, Azure), with a track record of executing platform migrations with minimal disruption.
  • Leads by example—sets technical bar through code reviews and design proposals, and thrives in a hands-on role balancing strategy with execution.

📝 Tips for Applying to Zoox

1

In your resume, quantify your monorepo scale (e.g., number of engineers, repos, builds per day) and highlight specific GitHub Enterprise migration experience.

2

Tailor your cover letter to mention Zoox's mission and how your work on source control directly enables autonomous vehicle development.

3

Showcase a project where you reduced developer toil (e.g., build times, merge friction) with measurable results—include metrics.

4

If you have experience with GitHub Cloud migration, emphasize it; otherwise, detail your approach to planning such a migration.

5

Mention any experience with monorepo tooling (e.g., Bazel, Buck) or large-file handling (Git LFS) to stand out.

✉️ What to Emphasize in Your Cover Letter

['Your hands-on experience scaling GitHub Enterprise monorepos and executing platform migrations.', 'How your CI/CD expertise (Buildkite, GitHub Actions) improves developer productivity and reduces merge friction.', 'Your ability to balance strategic roadmap ownership with daily operational excellence.', "Alignment with Zoox's mission and your interest in autonomous vehicle infrastructure challenges."]

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Read Zoox's engineering blog and any public talks on their infrastructure stack (e.g., autonomy stack, CI/CD).
  • → Understand Zoox's current vehicle development timeline and how source control impacts software delivery.
  • → Research GitHub Cloud vs. Enterprise features, especially around monorepo support and compliance.
  • → Look into Zoox's remote culture and how SRE teams collaborate across time zones.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Design a migration plan from GitHub Enterprise to GitHub Cloud for a 500-engineer org with a monorepo.
2 How would you optimize branch policies and merge automation to reduce merge friction in a monorepo?
3 Describe a time you improved build times or developer tooling—what metrics did you use?
4 How do you handle large files in a monorepo (e.g., Git LFS, external storage) without degrading performance?
5 Walk through your approach to setting code ownership and guardrails for a large engineering team.

⚠️ Common Mistakes to Avoid

  • Don't overemphasize generic SRE skills (e.g., on-call, monitoring) without tying them to source control and monorepo specifics.
  • Avoid vague descriptions of 'scaling'—provide concrete numbers and examples.
  • Don't ignore the migration aspect; failure to address GitHub Cloud migration suggests lack of fit for this role.
