Staff Frontend Engineer, Reddit

• 7+ years in front-end development, with 3+ years specializing in web components (LitElement/Lit, Svelte, etc.)
• Mastery of TypeScript, including advanced type utilities and monorepo workflows
• Proven experience building internal tools/frameworks
• Deep knowledge of backend integration patterns: REST, gRPC/Protobuf, OpenAPI specs, and BFF architectures
• Expertise in build tooling (Rollup, esbuild), testing (Web Test Runner), and CI/CD pipelines
• Strong communication skills to align stakeholders across engineering, product, and DevOps

Desirable

• The Technical Program Management Office (Tech PMO) exists to accelerate, scale, and empower all teams at Reddit to do their best work and advance our company’s mission
• We operate from within the office of the CTO, maximizing our ability to galvanize and drive technical programs, processes and solutions to solve company-wide problems
• As a Staff Frontend Engineer in the PMO, you’ll work closely with cross-functional teams to create a seamless and scalable internal tool development experience
• You’ll design and manage a scalable, reusable component library using LitElement and TypeScript, ensuring seamless integration with internal backend services (REST, gRPC, etc.)
• This role requires balancing technical leadership, cross-team collaboration, and hands-on development to empower engineers and improve productivity
• Design and implement a unified LitElement-based component library for internal tools, prioritizing reusability, accessibility, and performance
• Establish coding standards, documentation, and contribution workflows for cross-team adoption
• Optimize build pipelines (e.g., Webpack, Vite) for tree-shaking, testing, and versioning
• Create frontend patterns for consuming REST APIs, Protobuf schemas, and WebSocket streams
• Collaborate with backend teams to define API contracts, error-handling standards, and authentication flows (OAuth2, JWT)
• Implement shared TypeScript types/interfaces for API responses to reduce integration friction
• Build CLI tools or templates to scaffold new internal apps with preconfigured state management, routing, and API layers
• Mentor engineers on LitElement best practices, custom element lifecycle, and reactive programming
• Conduct code reviews and architectural audits to enforce consistency
• Profile and optimize rendering performance (e.g., lazy loading, memoization, pagination) for data-heavy internal tools
• Design a theming system with CSS custom properties and shadow DOM encapsulation
