About the Job

The Deployment Infrastructure team is hiring a Senior Full Stack Software Engineer to lead the design, development, and evolution of the web UI for our build and deployment platform. In this role, you’ll craft a cohesive, intuitive user experience that enables engineers across Reddit to build, test, and ship software safely and confidently to a globally distributed cloud ecosystem.

Our team owns continuous integration, continuous deployment, and the underlying systems that power build and deployment workflows. We’re looking for an engineer who operates at the intersection of frontend engineering, distributed systems and infrastructure, and developer experience.

In your day-to-day, you can expect to:

Design, build, and ship high-quality features across the stack, with a focus on creating reusable, maintainable UI components and polished frontends that scale with the platform

Contribute to backend systems to deliver cohesive, end-to-end product experiences

Define and enforce clean API boundaries between frontend and backend systems

Collaborate with teammates to build a platform that supports:

Orchestrating complex deployment workflows

Progressive rollouts across clusters and regions

Automated rollback of failed deployments

Observability into deployment health and performance

Translate complex infrastructure technologies and concepts (e.g., Kubernetes, Argo Rollouts, deployment policies) into intuitive, user-friendly interfaces

Engage directly with engineers across Reddit—conducting user interviews, gathering feedback, and deeply understanding developer workflows—to shape an opinionated “paved path” for releases

Raise the bar for full-stack engineering across the team through code reviews, mentorship, and knowledge sharing

Participate in the team’s on-call rotation and contribute to the reliability of our platform

Continuously grow your technical and non-technical skills

You Have:

5+ years of experience building full-stack applications, with strong frontend expertise

Deep proficiency in modern frontend development; experience with component-based frameworks (e.g., React, Lit) is valuable, but strong fundamentals matter most

Solid backend experience and understanding of API design, service boundaries, and system architecture

Experience with CI/CD, build systems (e.g., Buildkite, GitHub Actions, Drone) and progressive delivery tools (e.g., Argo Workflows/Rollouts/CD, Kayenta)
