🚀 Join the Future of Commerce with Whatnot!

Whatnot is the largest livestream shopping platform in North America and Europe to buy, sell, and discover the things you love. Whether it's trading cards, fashion, electronics, or live plants, our sellers are building real businesses across hundreds of categories. We're building live commerce at a scale that's never been done in the West, and there's no playbook to copy. The people here are shaping how an entirely new industry develops.

As a remote co-located team, we're inspired by our values and anchored in hubs across the US, UK, Ireland, Poland, Germany, and Australia. We move fast, stay close to our users, and focus on the work that drives the most impact.

We're one of the fastest growing marketplaces and were recently named the #1 Best Startup Employer in America by Forbes. Check out the latest Whatnot updates on our news and engineering blogs and join us as we enable anyone to turn their passion into a business and bring people together through commerce.


💻 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.


👋 You

People who do well at Whatnot tend to be comfortable figuring things out as they go, biased toward action, and genuinely curious about what they're building. They care more about outcomes than credit and stay close to the product and the people using it.

  • Proficiency in Swift, with a deep understanding of iOS fundamentals and SwiftUI-driven UI architecture.

  • Proven track record of delivering user-facing features. You are known for shipping products and features lightning-fast.
