MoonPay - Senior Software Engineer, Developer Platform
Requirements
• External developer products. You have built APIs, SDKs, embedded components or integration tooling used by third-party developers. • JavaScript and TypeScript. You have strong language fundamentals and have built production client-side or SDK infrastructure. • API and SDK design. You understand versioning, backwards compatibility, documentation, error design and safe migrations. • Distributed systems. You build correctly when events arrive twice, late or out of order and when dependencies fail. • Product judgement. You can turn complex platform capabilities into interfaces that developers can understand and adopt. • Ownership. You have taken developer-facing software from design through launch, adoption and ongoing production support. • Built payment APIs, checkout SDKs, embedded financial products or payment-method integrations. • Built products similar to Stripe Elements, Stripe.js, Plaid Link or Braintree’s client SDKs. • Experience with secure iframes, web views, postMessage or cross-origin browser infrastructure. • Developed SDKs across web, iOS or Android. • Built sandboxes, test environments, reference applications or developer documentation. • Experience with webhooks, idempotency, transaction state machines and payment orchestration. • Worked on authentication, identity or KYC integrations. • Familiarity with cryptocurrency, wallets or digital-asset products. • Familiarity with our stack: TypeScript, Node.js, React, GCP, PostgreSQL, Redis and Kubernetes. • 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.
