Senior Frontend Software Engineer, Consumer Engineering

Reddit is a community-driven platform built around shared interests, conversations, and trust. The Senior Frontend Software Engineer will build and scale consumer products, partnering cross-functionally to deliver reliable, low-latency experiences, APIs, experiments, and scalable features for Reddit users.

Responsibilities:

• 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

Requirements:

• • User-Centric Mindset: An advocate for the user with an intuitive feel for product usability, interaction design, social dynamics, and user growth loops. You care deeply about why a feature is being built and its impact on the end user
• • Data-Informed & Hypothesis-Driven: Comfortable working alongside Data Scientists and PMs to design experiments, establish core performance metrics, and iterate quickly based on real-time feedback
• • Technical Rigor at Scale: 5+ years of hands-on backend development experience building and operating large-scale distributed serving systems in high-concurrency environments
• • Bias for Action: Self-directed, innovative, and comfortable navigating ambiguity in fast-paced product environments where balancing velocity with system reliability is essential
• • Collaborative Communicator: Outstanding communication skills with a track record of driving cross-functional alignment in fully remote or hybrid team environments
• • 6+ years of software development experience in one or more front end focused programming languages; Javascript, Typescript, ES6
• • Experience with one or more front-end web frameworks such as LIT, Polymer, React, Vue, or Angular with experience with CSS
• • Modern Workflows: Experience or interest in using AI-assisted engineering tools to accelerate development workflows
• • Experience with GraphQL, REST, HTTP, Thrift basics, and the ability to design and implement maintainable APIs is a plus
