Job description

Principal UX Engineer at Reddit - $344K + RSUs — Remote

Career Level & Compensation: At $245,800–$344,100 USD, this Principal-level role sits at the top of individual contributor tracks. For context, Principal UX Engineer or equivalent roles at top-tier tech companies typically range from $220K–$320K total base — Reddit's range is competitive and skews high. Add RSU equity and this package is firmly in FAANG-adjacent territory.

Skills You\'ll Develop: This role is a rare opportunity to deepen a high-demand hybrid skillset:

• AI-native prototyping and agent-based tooling — one of the fastest-growing areas in product development.
• Frontend systems thinking at scale (React, TypeScript, design systems).
• Cross-functional influence at the Principal level, working alongside senior leaders across Product, Engineering, and Data Science.
• UX Engineering as an organizational capability — establishing a practice, not just executing within one.

Green Flags: Reddit explicitly values staying hands-on while growing others — a healthy signal for ICs who don\'t want to be forced into pure management. The role spans multiple product areas, reducing the risk of career stagnation on a single narrow project.

Watch For: The posting spans "more than one career level," which can mean flexibility in leveling, but also ambiguity about scope. Clarify expectations around IC autonomy vs. managerial responsibility early. The advertising domain can be niche — ensure the skills built here (AI tooling, design systems, prototyping infrastructure) remain transferable.

Overall: An excellent role for a senior design-engineer hybrid ready to define a practice and work at a prominent public company.

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.

Reddit\'s Ads Design & Research team shapes the end-to-end advertising experience across advertiser tools, consumer ad experiences, measurement, and the systems that connect them.

We\'re looking for a Principal UX Engineer who sees code as a product-design medium: a way to make ideas tangible, connect prototypes to real systems and data, and help teams move from exploration to engineering-ready product direction faster.

This is a strategic, hands-on role at the intersection of design and engineering. You\'ll work across Reddit Ads to shape product direction, build production-adjacent prototypes and tools, and help establish UX Engineering as a capability for the Ads Design team.

You\'ll partner closely with Design, Research, Product, Engineering, and Data Science while staying deeply involved in the craft.

What You\'ll Do

• Define and lead the UX Engineering strategy across multiple areas of Reddit Ads.
• Build high-quality functional prototypes, workflow tools, agents, and PR-ready product experiences that help teams explore ideas, test assumptions, and move faster from design intent to engineering review.
• Partner with senior cross-functional leaders to shape product direction and bring clarity to complex, ambiguous opportunities.
• Create reusable tools, systems, components, and workflows that make it easier to move from design and research into production.
• Raise the bar for interaction quality, accessibility, performance, and technical craft across the Ads experience.
• Build AI-native workflows, skills, agents, and tools that improve how Ads Design explores, prototypes, collaborates, and ships.
• Mentor other practitioners and help grow UX Engineering as a capability across Reddit.

What We\'re Looking For

• Deep experience at the intersection of product design and engineering, with a track record of building sophisticated interactive products.
• Strong hands-on expertise with modern frontend technologies such as React and TypeScript.
• Experience building production-adjacent prototypes, internal tools, systems, or frontend infrastructure that other designers and engineers can use.
• Excellent product and interaction judgment, with the ability to turn complex ideas into intuitive, high-quality experiences.
• Experience working across multiple teams or product areas and influencing product direction beyond a single project.
• Strong systems thinking, with experience creating reusable patterns, platforms, or tools that help other teams move faster.
• Fluency with AI-assisted coding, agents, and advanced prototyping workflows.
• The ability to navigate ambiguity, make thoughtful tradeoffs, and bring design, engineering, product, and research perspectives together.
• Strong communication and collaboration skills, particularly with senior cross-functional partners.
• A portfolio or body of work that shows use cases, technical architecture, systems thinking, organizational complexity, and collaboration with engineering teams — not only polished UI outcomes.
• A passion for staying hands-on while helping others do their best work.

Experience in advertising is helpful, but it isn't required. We\'re also interested in people who have worked on complex products such as marketplaces, enterprise tools, analytics, commerce, developer platforms, AI-powered experiences, or other multi-sided ecosystems.

Benefits

• Comprehensive Healthcare Benefits and Income Replacement Programs
• 401k with Employer Match
• Global Benefit programs that fit your lifestyle, from workspace to professional development to caregiving support
• Family Planning Support
• Gender-Affirming Care
• Mental Health & Coaching Benefits
• Flexible Vacation & Paid Volunteer Time Off
• Generous Paid Parental Leave
