Staff Frontend Engineer

Summary

Join Reddit's Technical Program Management Office (Tech PMO) as a Staff Frontend Engineer and contribute to the development of seamless and scalable internal tools. Work closely with cross-functional teams to design and manage a reusable component library using LitElement and TypeScript. You will be responsible for backend integration, developer experience improvements, and performance optimization. This role requires strong technical leadership, collaboration skills, and hands-on development experience. The position is 100% remote and open to candidates located in the United States. A competitive salary and benefits package are offered.

Requirements

• 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

Responsibilities

• 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

Preferred Qualifications

• Contributions to open-source web component libraries
• Familiarity with WebAssembly for performance-critical tooling modules
• Knowledge of backend languages (Go, Python) to prototype integration layers
• Experience with AI tools that maximize productivity
