Role

App Platform is Whatnot's client infrastructure team, building the consistent, reliable foundation that every product team builds on top of across iOS, Android, and web. Rather than owning a single feature surface, the team pushes technical boundaries so product pods can move fast without sacrificing quality — owning things like app stability, the Whatnot Design System, localization, core components, and the shared architecture that keeps our apps performant and consistent at scale. As an iOS Engineer on App Platform, you'll focus on the infrastructure and building blocks that feature teams rely on: architecting and maintaining core components and the design system, strengthening our networking and persistence layers, driving app stability and crash reduction, and partnering closely with product teams to make sure the right way to build is also the easiest way. It's a high-leverage role for someone who wants their work to compound across the entire app rather than a single feature. 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. Bachelor’s degree in Computer Science, a related field, or equivalent practical experience. 5+ years of professional software engineering experience building and shipping iOS platform or products. 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. Excellent product instincts. You first think about users rather than the best technical solution. Bonus: Experience with e-commerce or social products. Familiarity with A/B testing frameworks, analytics instrumentation, or growth experimentation tooling.
