Software Engineer — Sweeps

Sweeps is a mobile app where people open packs of real graded trading cards and either keep what they pull or sell back instantly at 100% of fair market value. Every rip is a real card, every pull has real value, and the whole experience has to feel exciting, satisfying, and trustworthy — the moment of opening a pack is the product.

We're a small, fast-moving remote team. You'd be one of our earliest engineering hires, working directly with the founders to build the app people actually open and rip on every day.

What you'll work on

• The core ripping experience — the flows, animations, and feel of opening a pack and seeing your pull
• Funding and instant sell-back: making the money-in and money-out moments seamless and instant
• The screens users live in — collection, pull history, pack selection, onboarding
• Real-time pricing so every card shows an accurate, up-to-the-moment value
• Speed and reliability across the app; if a rip lags or a value looks wrong, the magic breaks
• Fast iteration on new pack types, mechanics, and features that keep people coming back

What we're looking for

• Strong engineer who's shipped real, polished consumer apps end to end
• An eye for product and UX — you care how a tap feels, not just that it works
• Comfort owning features from idea to shipped, and moving fast without cutting corners on correctness
• Solid fundamentals in APIs, state, and building responsive real-time interfaces
• Bias toward action; thrives in a high-ownership, early-stage environment

Nice to have

• Mobile experience (React Native, Swift, or Kotlin) and a track record of working on apps people love using
• Payments or money-movement experience
• Interest in trading cards, collectibles, or the pack-ripping community
