Role

We're hiring iOS Engineers across multiple teams, including Buyer Growth, Content & Navigation, Security, App Platform, and Customer Experience & Operations. Our hiring needs span a range of seniority levels — from mid-level to senior and staff-level leaders — and we thoughtfully align scope and leveling based on experience and demonstrated impact. Team matching happens in the later stages of the process, allowing us to pair you with the team where your strengths, interests, and growth goals will have the greatest impact.

As our next iOS Engineer, you'll design and build mobile experiences and systems that sit at the heart of the seller and buyer experience—combining growth, trust, and scalability. Your work will directly shape how thousands of new sellers and buyers discover Whatnot, get started, and succeed every week.

• Develop high-quality iOS features using Swift and SwiftUI.

• Collaborate cross-functionally with product, design, and backend teams to define goals, scope, and technical trade-offs.

• Contribute to the evolution of shared mobile infrastructure and best practices across Whatnot's engineering teams.

• Uphold engineering excellence through code reviews, documentation, and thoughtful discussions that raise the bar.

We offer flexibility to work from home or from one of our global office hubs, and we value in-person time for planning, problem-solving, and connection. Team members in this role must live within commuting distance of our New York, Seattle, San Francisco or Los Angeles hub.
