About this role
At Coinme, we’re redefining access to financial services in a digital world. By combining the cutting-edge power of blockchain technology with everyday simplicity, we make digital currencies accessible and usable for all. As the world's largest network of cryptocurrency kiosks with over 40,000 locations nationwide, we're breaking down barriers to crypto adoption through our seamless mobile app, secure digital wallet, and DeFi integrations.
Beyond our consumer offerings, we're also the infrastructure powering the crypto revolution for businesses. Through our enterprise Crypto-as-a-Service (CaaS) platform, we enable businesses to launch crypto capabilities in weeks, not months. Our modular, API-first infrastructure provides everything from KYC and payment processing to liquidity and custody solutions—all fully licensed and compliant. We’re big enough to lead the charge in decentralized finance but small enough that your ideas will make waves.
Every role at Coinme contributes to building a financial future where everyone has the tools to thrive. At Coinme, your growth fuels our mission. Together, we RISE. Technical Solutions Engineer, Payments About the Role Coinme is part of Polygon Labs, and together we're building the Open Money Stack: one integration for wallets, compliance, fiat on and off ramps, and settlement. Coinme brings the regulated US fiat layer, built over nearly a decade with money transmitter licenses, 50,000+ retail locations, and over $1B processed.
The stack is live and fintechs and financial institutions are integrating it now. This role owns the technical experience of building on us: our API documentation and integration path, the technical answers partners need during a sales conversation, and getting signed partners from kickoff to production. You'd be defining what good looks like, with the room to set the standard and the mandate to hold it. The bar we're setting is the best developer experience in payments: a competent developer working with an AI coding assistant should be able to integrate us without needing to talk to us at all.
This is a senior individual contributor role with deep technical ownership. What You'll Do Own the API and integration docs. Rewrite what's wrong, fill what's missing, keep it current as the stack changes Build the quickstarts, sample code, and reference architectures that get a developer from nothing to a working integration Answer technical questions from partners during sales conversations and during builds, and resolve them yourself rather than passing them to engineering Take signed partners live: requirements intake, provisioning once KYB and KYC clear, sandbox testing, webhooks, go-live checks Work with the integration program manager on timelines so partners know what's coming and when Learn the stack deeply: CaaS ramps, Sequence wallets, Trails, OMSX, bank rails, custodial and non-custodial flows, virtual accounts, deposit addresses, webhooks Build demos and sample apps that BD can use to show what the products do Push what you learn back into Product and Engineering.
