Every day, Reddit users submit, vote, and comment on the topics they care most about. With 100,000+ active communities and approximately 130 million daily active unique visitors, Reddit is one of the internet’s largest sources of information. For more information, visit www.redditinc.com .

Team Description

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.

Role Description

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.

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.

Responsibilities

• 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.

Required Qualifications

• Comfort using Codex, Cursor, Claude, or comparable agentic coding tools in day-to-day software development.
• A track record of independently delivering complex frontend projects from technical design through launch and iteration.
• Sound judgment in frontend architecture, state management, component design, testing, and API integration.
• Experience building polished user interfaces with close attention to usability, performance, accessibility, and maintainability.
• 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.
• A habit of improving engineering quality through code reviews, documentation, and technical mentorship.
• 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.

Technologies used on the team include

• Modern frontend testing, experimentation, and observability tools
• Comprehensive Healthcare Benefits and Income Replacement Programs
• 401k Match
• Family Planning Support
• Mental Health & Coaching Benefits
• Flexible Vacation & Reddit Global Days Off
