Senior Frontend Engineer

• The Ads Creative & Recommendations team makes it easier for advertisers to maximize performance on Reddit through relevant creative and actionable recommendations.
• We own the advertiser-facing workflows where creative, recommendations, and campaign creation come together.
• Our goal is to reduce blank-canvas work and help advertisers move from an idea to an effective campaign with less friction. We build unified experiences that give advertisers useful context, evidence-backed guidance, and the ability to refine the system’s suggestions.
• We’re looking for a senior frontend engineer with deep JavaScript, TypeScript, and React experience to help shape the next generation of Reddit’s advertiser tools.
• You’ll independently own complex and sometimes ambiguous areas of the product, from technical design through launch and iteration.
• You’ll work closely with product, design, data science, machine learning, and backend engineering to turn sophisticated capabilities into workflows that feel simple and dependable.
• Own the technical design and delivery of complex frontend features across Ads Manager’s creative and recommendation workflows.
• Translate AI-backed capabilities into interfaces that advertisers can understand, steer, and refine.
• Partner with product and design to work through ambiguous requirements and make sound product and engineering tradeoffs.
• Develop reusable frontend patterns and components that support a unified campaign creation experience.
• Instrument experiences, evaluate results, and use experiments and product data to guide iteration.
• Raise the quality of the codebase through thoughtful architecture, testing, observability, performance work, and accessibility.
• Provide high-quality code reviews and technical guidance, and help other engineers grow.
• Collaborate across frontend, backend, data, and machine learning systems to deliver reliable end-to-end experiences.

Technologies used on the team include:

• JavaScript
• TypeScript
• React
• Modern frontend testing, experimentation, and observability tools

Benefits

• Comprehensive health benefits
• Flexible vacation & Reddit global days off
• Family planning funds & 4+ months paid parental leave
• Personal & professional development funds
• Paid volunteer time off
• Workspace & home office benefits

This role is a strong fit for someone who cares about both the architecture behind a frontend system and the details that make a product intuitive, fast, accessible, and maintainable.

• Ability to work effectively through ambiguous product and technical problems.
• Strong communication and collaboration skills across engineering, product, design, and data disciplines.
• Experience using instrumentation, experimentation, or product metrics to understand and improve user experiences.
• 5+ years of experience building production web applications with JavaScript, TypeScript, and React.
• A habit of improving engineering quality through code reviews, documentation, and technical mentorship.
• Comfort using Codex, Cursor, Claude, or comparable agentic coding tools in day-to-day software development.
• Sound judgment in frontend architecture, state management, component design, testing, and API integration.
• A track record of independently delivering complex frontend projects from technical design through launch and iteration.
• Experience building polished user interfaces with close attention to usability, performance, accessibility, and maintainability.
• Experience building advertising, campaign management, creative tooling, or other complex business applications.
• Experience designing interfaces for generative AI, machine learning, or recommendation systems.
• Familiarity with asset management, media upload, image editing, creative versioning, or content generation workflows.
• Experience building or contributing to shared component libraries and design systems.
• Experience improving large frontend codebases through architecture, performance, testing, or accessibility work.
