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.

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

• Mobile: React Native, Expo, TypeScript
• Frontend: React, Next.js, TypeScript, Tailwind CSS
• Backend/Data: Supabase, PostgreSQL, Python, Node.js
• Infrastructure: Vercel, AWS, Porter
• Payments/Marketplace: Stripe, Stripe Connect
• Analytics/Data: PostHog, SQL, internal pricing and catalog pipelines

You might be a fit if you…

• Have 1+ years of software engineering experience, or equivalent experience building and shipping real products
• Have experience building and shipping React Native applications, ideally with Expo
• Are strong with React, TypeScript, modern frontend patterns, and mobile-first product development
• Are comfortable working with PostgreSQL, SQL queries, data models, and product logic
• 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

React Native, React, and PostgreSQL experience are required for this role. Next.js experience is a plus, but not required.

Bonus points if you have experience with:

• Supabase
• Expo
• Marketplace products
• Stripe / Stripe Connect
• Search, filtering, inventory, or catalog systems
• Growth, conversion, onboarding, or retention experiments
• Mobile app performance, app store releases, or mobile CI/CD
• Pokémon, TCGs, collectibles, or hobby marketplaces

How to apply

• Apply with your resume and any links that help us understand what you’ve built, such as LinkedIn, GitHub, portfolio, or app links.
• You’ll also answer a few short questions about your React Native, React, and PostgreSQL experience, a product or feature you’re proud of, and why you’re interested in Misprint.

Our process is designed to be straightforward and conversational:

• Intro call to learn more about Misprint, the role, and your background.
• 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.
