What the role involves
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

Have good product taste and care about UX, speed, reliability, and polish

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

What they ask for
About Misprint
Misprint is an all-in-one marketplace that solves the biggest pain point in the collectibles world: opaque pricing. Collectors, investors, and hobbyists currently rely on scattered data from auction houses, online forums, and reseller platforms, making it difficult to know the true value of their items. Misprint streamlines the process by combining accurate pricing analytics with a seamless buy/sell marketplace, making it easier than ever to understand and monetize collectible assets. Existing marketplaces lack robust, real-time analytics because accurate valuations require deep expertise in both the collectibles domain and advanced pricing algorithms. Misprint’s unique blend of insider trading card knowledge and machine learning allows us to fill this gap. Building these pricing models requires extensive data infrastructure, deep domain expertise, and cutting-edge ML. Recent surges in the trading card market show that collectors crave transparent valuations. The global collectibles market is worth tens of billions of dollars. Eva has experienced the scale of this industry firsthand, generating $500k ARR within three months of taking her Pokemon card-selling side hustle full-time. With additional segments like sports cards, comics, and emerging collectible categories, the growth runway is immense. Co-founders Eva and Jon have been best friends since Exeter, combining finance expertise, a passion for collectibles, and mathematical rigor. By merging Goldman Sachs-level financial analytics with top-tier mathematical talent, Misprint is uniquely positioned to become the go-to platform for fair, transparent pricing in the collectibles space.
