Software Engineer, Release Engineering at Zapier (L3/L4) — owning CI/CD and delivery infrastructure for every engineer
Zapier is hiring L3/L4 Software Engineers for a new India-timezone Release Engineering team that owns CI/CD pipelines, testing infrastructure, and release orchestration for the whole engineering org. The interview weighs production backend engineering fundamentals against platform-engineering depth — building and improving delivery systems, not just using GitLab CI/Kubernetes/ArgoCD/Terraform as a consumer.

What this interview tests
- Building/improving CI/CD pipelines and testing infrastructure (not just using them)
- Hands-on platform tooling: GitLab CI, Kubernetes, Docker, ArgoCD, Terraform
- Production backend/fullstack engineering fundamentals (TypeScript, Node.js, Python or equivalent)
- Driving loosely-defined problems to production: design docs, success criteria, rollout, measurement
- Systems thinking with downstream engineers as first-class users; defining 'golden paths'
- L4: technical leadership, mentoring, cross-team platform dependency coordination
Common question themes
Tell me about a CI/CD pipeline or test suite you diagnosed and fixed — what was the root cause
Describe a release/delivery system you built or significantly improved, and the tools involved
How do you define a 'golden path' for how code gets built and shipped, and drive adoption of it
Walk me through taking an ambiguous platform problem from design doc to production rollout
(L4) Tell me about leading technical design for a project with cross-team dependencies
How do you use AI tools in your engineering workflow, and how do you validate their output
Describe how you'd coordinate an incident response when a release pipeline breaks for the whole org
