[Hiring] Senior Software Engineer, Infrastructure Engineering @Reddit

Role Description

The Infrastructure Engineering team enables Reddit to deliver Reliability, Performance, and Efficiency, with a single opinionated technology stack. We empower Reddit developers by delivering a reliable, scalable, and automated foundation - unifying compute, seamless deployments, robust storage, and high-performance messaging to maximize developer velocity and system resilience.

This centralized role hires across several high-impact teams, including:

• Messaging: Delivers a reliable, performant, and efficient platform to support asynchronous communication across all products and services at Reddit.
• Compute: Provides a resilient, high-performance, and cost-effective abstraction layer that streamlines application deployment and execution management across systems.
• Build & Deployment: Builds platforms and developer tooling that enable engineers to build, test, and safely deploy software across Reddit’s infrastructure.
• Consumer IAM: Authentication, authorization, and account infrastructure services.
• Core Systems & Libraries: Builds the foundational services that power Reddit.
• Security: Builds software that improves the security and reliability of Reddit’s infrastructure.

What You’ll Do:

• Cross-Functional Product Architecture: Partner closely with Product Management, Product Design, Data Science, and Client Engineers (iOS/Android/Web) to translate business and user needs into reliable, low-latency technical solutions.
• End-to-End Delivery: Own the full software lifecycle for major product initiatives from technical design docs and API contracts to development, testing, rollout, and observability.
• Metrics & Experimentation-Led Engineering: Design, build, and evaluate A/B experiments. Work with tools like BigQuery, HEX, or Firebase to analyze user behavior, conversion funnels, and retention loops to make data-backed engineering decisions.
• API & System Performance: Build and maintain scalable APIs (GraphQL, REST, gRPC) and distributed backend services optimized for client consumption and consumer UI performance.
• Technical Rigor & Modern Tooling: Establish engineering best practices, improve developer workflows, mentor teammates, and use modern, AI-integrated tools to ship high-quality products efficiently.

In your day-to-day, you will:

• Steer: Work with the team to select, scope, and drive high leverage projects that align with Reddit’s goals.
• Build: Execute on a strategy and create a more performant, more scalable, higher quality architecture around authentication, authorization and identity.
• Amplify: Mentor, coach, and collaborate with other technical contributors.
• Collaborate: Work together with a variety of cross functional teams across Reddit Engineering.
• Evolve: Learn and improve your own technical and non-technical abilities.
