Rain is the global stablecoin payments platform for enterprises, neobanks, platforms, developers, and AI agents. Our technology allows partners to move, store, and use stablecoins instantly and compliantly through global payment cards, rewards, on/offramps, wallets, and cross-border rails. As both a Visa and Mastercard Principal Member, Rain issues cards that work at more than 175 million merchant locations in over 220 countries and territories. Built natively for stablecoins and trusted by more than 100 organizations worldwide, Rain delivers secure, scalable infrastructure that makes money move freely and instantly around the world.
You will have the opportunity to deliver massive impact at a hypergrowth company backed by some of the top investors in fintech, crypto, and SaaS. In January 2026, we closed a $250M Series C led by ICONIQ, valuing Rain at $1.95B, with Sapphire Ventures, Dragonfly, Bessemer Venture Partners, Galaxy Ventures, FirstMark, Lightspeed, Norwest, and Endeavor Catalyst also participating. If you're curious, bold, and excited to help shape a borderless financial future, we'd love to talk.
We believe in an open and flat structure. You will be able to grow into the role that most aligns with your goals. Our team members at all levels have the freedom to explore ideas and impact the roadmap and vision of our company.
Security Engineering is a small team that answers one question: was it built right? We run our own AI-driven red team against Rain's code and cloud, gate pull requests before they merge, and write the baselines that say how every system should be configured. Our blockchain work is covered. This role owns everything else: the backend services, APIs, cloud, and edge that move real money for real customers.
We work closely with Security Operations: we give them high-quality findings to coordinate fixes for, and clear configuration rules they can build detections on.
Security Engineering makes sure Rain is built right. We run our own AI-driven red team against our code and cloud, gate pull requests before they merge, and set the baselines for how every system is configured. This role owns everything outside blockchain: the backend services, APIs, cloud, and edge that move real money. We give Security Operations high-quality findings to coordinate fixes for, and clear configuration rules to build detections on.
You'll be Rain's application security expert and the quality bar for every non-chain finding we produce. The calls are yours: what's real, how bad it is, and what has to be fixed before launch. You'll hold the line with engineers when it matters, and make the case so they agree, not just comply.
