Mobile Engineer at Misprint, Inc. Mobile Engineer at Misprint, Inc. in Weehawken, New Jersey Posted in 3 days ago.
Type:
full-time
Job Description:
Misprint is a YC-backed marketplace for Pokémon cards - think StockX for collectibles, built around real-time pricing, liquidity, transparency, and trust. We're building the category-defining marketplace for one of the largest collectible markets in the world. Pokémon cards are a massive, highly liquid, global market, but buying and selling them is still fragmented, opaque, and full of friction. Misprint is changing that with live market data, a real bid/ask system, better seller tooling, and a much more trustworthy collector experience. We're hiring a Software Engineer to help us move faster on our mobile app and core marketplace product. This is a high-ownership role for someone who can build polished React Native experiences while also being comfortable working across the product stack when needed - especially with PostgreSQL, Supabase, and data-backed marketplace features. You'll work directly with the founders and engineering team to improve the buyer and seller experience, ship mobile-first product improvements, and help turn Misprint into the default place collectors buy and sell Pokémon cards. What you'll do You'll primarily work on: Our iOS and Android apps built with React Native / Expo Core buyer and seller flows, including listing, browsing, offers, checkout, orders, and account experiences Mobile-first UX improvements across onboarding, discovery, search, card pages, collections, watchlists, and seller tools Product features that rely on PostgreSQL/Supabase data models, queries, permissions, and marketplace state Frontend polish, navigation, performance, and reliability across key user journeys Growth/product experiments that improve activation, conversion, retention, repeat purchase behavior, and marketplace liquidity This is not a pure mobile-only role, but mobile will be a major focus. You should be excited to own React Native product work while still being comfortable understanding and working with the underlying data/product logic. What success looks like in your first 60-90 days You've shipped meaningful improvements to our mobile app and core marketplace flows You understand our product, users, and marketplace mechanics well enough to propose improvements You've taken ownership of at least one important mobile or product area You're comfortable working with React Native, TypeScript, PostgreSQL, and Supabase-backed product logic You're helping us move faster without creating fragile systems The product feels better because of the details you notice and fix Our stack

Technical interview with the engineering team. This is not a LeetCode-style interview; we'll ask practical questions about products and systems you've built, how you approach React Native/product engineering work, and how you think through tradeoffs. Potential additional founder or team interview if helpful, focused on working style, ownership, and role fit. Offer conversation covering compensation, equity, start date, and next steps. We care most about whether you can ship real product, communicate clearly, and operate well in an early-stage startup environment.
