About the role

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

Logistics

Location: In-person, New York City

Type: Full-time

Compensation: $120k–$180k salary + 0.2%–0.6% equity

Start date: ASAP

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.

About the interview

Our process is designed to be straightforward and conversational:

1. Intro call to learn more about Misprint, the role, and your background.
2. 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.
3. Potential additional founder or team interview if helpful, focused on working style, ownership, and role fit.
4. 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.
