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)
• Familiarity with Temporal, Kubernetes, and cloud platforms (AWS, GCP)
• Excellent communication skills that you employ to drive alignment, to navigate tradeoffs, to influence decisions and priorities, and to empower others
• A high degree of empathy, curiosity, and humility, with a passion for improving both developer experience and Reddit’s reliability
• A strong sense of ownership. You take initiative, lead projects end-to-end, and go beyond your immediate scope to ensure successful outcomes and drive impact across the platform
• A self-directed, action-oriented approach. You are comfortable operating in ambiguity, learning quickly, and driving work forward even when the path is not fully defined

Bonuses:

• Experience on developer experience, infrastructure, or platform teams
• Experience building systems for CI/CD, progressive delivery, or other internal developer platforms
• Experience conducting user research or gathering feedback from technical users
• Experience with implementing UI/UX design yourself and comfort with design software such as Figma
• Experience with backend-adjacent technologies such as GraphQL, REST, HTTP, gRPC, or Go
• Familiarity with multi-cluster or multi-region deployment strategies
• Interest in exploring and integrating emerging technologies (e.g., generative AI) to improve developer workflows

Benefits:

• Comprehensive Healthcare Benefits and Income Replacement Programs
• 401k with Employer Match
• Global Benefit programs that fit your lifestyle, from workspace to professional development to caregiving support
• Family Planning Support
• Gender-Affirming Care
• Mental Health & Coaching Benefits
• Flexible Vacation & Paid Volunteer Time Off
• Generous Paid Parental Leave
