Bitrefill (United States) - Shop for Gift Cards, eSIMs, and Mobile Recharges with BTC, ETH, USDT, USDC, and more. Pay online with crypto in over 186 countries. Backed by 500 Global.
About the role
Bitcoin and Lightning are where Bitrefill comes from, and they're still core to what we do. There's more happening in this space than the team can keep up with, so we're bringing in more hands to keep things running and push them forward: shipping the integrations we keep talking about, digging into how our payments actually flow, and turning "we should really do this" into things that are live.
What they're looking for
- Several years building software professionally, with a track record of shipping real things
- AI is part of how you build (Claude Code, Codex, Cursor, or similar). This is non-negotiable for us
- Deep understanding of the Lightning Network protocol and Bitcoin fundamentals
- Hands-on experience with at least one Lightning implementation (LND, CLN, Eclair, or LDK)
- Strong with our backend stack, Node.js and TypeScript, and comfortable working in Python
- Crypto-native. You use it, you follow where it's headed, and nobody needs to explain Bitcoin to you
