Software Engineer ( Full Stack & Mobile ​/ React Native

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.

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.

• 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, Type Script, 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

• Have good product taste and care about UX, speed, reliability, and polish
• Can take a product problem and turn it into a shipped feature
• Communicate clearly, operate independently, and document as you go
• Like owning outcomes, not just completing tickets
• Are excited by marketplaces, payments, pricing data, trading cards, collectibles, or Pokémon
