## Description

About MoonPay MoonPay is for builders with something to prove. This isn't a "work on cool crypto stuff" company. It's a high-standards, high-velocity, high-accountability company building the operating system for value movement. If the internet moves information, we move value: crypto, stablecoins, tokenized assets, and whatever comes next. Four offerings make that real: fund, tokenize, trade, and spend. 30M+ customers and 500+ ecosystem partners run on us. Licensed in the U.S. Regulated across the UK, EU, Canada, and Australia. AI is the default operating mode here. It's woven into every role, and we expect you to use it daily. It handles the manual work so you can deliver on what actually matters. You'll thrive here if outcomes excite you more than process, if impact motivates you more than titles, and if you want hard problems, real ownership, and teammates who love winning, building, and doing it together. The bar is high. The pace is real. We're building for what's next, for humans and agents. Recent recognition: Forbes' America's Best Startup Employers 2026 . 2nd in Crypto Services on Fortune's inaugural Crypto 100 The Sunday Times Best Places to Work two years running Research has shown that women are less likely than men to apply for this role if they do not have experience in 100% of these areas. Please know that this list is indicative, and that we would still love to hear from you even if you feel that you are only a 75% match. Skills can be learned, diversity cannot. About the Opportunity MoonPay is building a developer platform that allows partners to create native payment and crypto experiences directly inside their own products. Historically, partners integrated MoonPay through a hosted widget and redirected users into a fixed MoonPay journey. We are now breaking the underlying system into reusable modules covering authentication, identity, KYC, quotes, payment methods and purchasing. These capabilities are exposed through APIs, SDKs, embedded components, iframes and web views. Our goal is for a partner developer to integrate MoonPay’s full capabilities without needing ongoing implementation support from our team. This role owns the developer-facing layer between MoonPay’s underlying payments infrastructure and the products our partners build. You will work across browsers, mobile applications and backend APIs to make complex financial workflows feel simple, predictable and native. As a Senior Software Engineer, you will hold a hands-on technical position. You will build the platform itself rather than implementing one-off integrations for individual customers. Build the developer platform Design and build APIs, SDKs and embedded components used by external developers. Turn MoonPay’s existing authentication, identity, payment and purchasing capabilities into reusable platform modules. Develop secure browser and mobile integration patterns across iframes, web views and native applications. Create stable abstractions over complex payments, compliance and crypto infrastructure. Build reference applications, sandboxes and tooling that help developers move quickly from exploration to production. Understand the integration deeply Own the complete developer journey, from obtaining credentials through to completing a live transaction. Design clear interfaces for sessions, authentication, quotes, payment methods, transaction state and errors. Handle the realities of browser and mobile environments, including cross-origin communication, redirects, storage restrictions and application lifecycle events. Develop consistent behaviour across web, iOS and Android integrations. Ensure integrations remain secure when operating inside products MoonPay does not control. Make complex systems easy to use Design APIs and SDKs that are difficult to misuse and straightforward to debug. Establish clear versioning, compatibility and migration strategies. Build documentation around how developers actually use the platform rather than
