Description
Product Engineer
Team: Engineering
Location: New York, NY
Commitment: Full-time
Workplace Type: hybrid
At Fun, we believe a tokenized future is a beneficial inevitability, granting financial emancipation to everyone with an internet connection. For a blockchain-first global economy to exist, value exchange must become intuitive, secure, and seamless.
Enter Checkout - the highest converting payment solution in web3. By integrating Checkout, dApps enable users to complete any on-chain action using crypto from a wallet, centralized exchange, or on-ramped fiat from a card or bank account. With access to market-leading routing and their asset portfolio at the point of sale, users are faster, stickier, and more engaged. For dApps, Checkout scales their user acquisition potential without launching new chains or integrating multiple third party providers.
We built Checkout because we envision a world where anyone, anywhere, can purchase anything with any asset. If that sounds like a vision you can get behind, we want to hear from you.
About the Role
We're looking for a talented Product Engineer (Mid, Senior, Staff) to join our team and help shape the future of crypto payments. In this role, you'll design and scale SDK software that powers Checkout across web2 and web3 environments, working across the stack on systems that balance performance, reliability, and UX. You'll collaborate closely with protocol, backend, and business teams to solve complex challenges and build tools that scale globally to meet the evolving demands of on-chain payments. Crypto experience is a plus, but fast learners from any technical background are welcome.
