Staff Software Engineer, Identity Platform

About the Opportunity

MoonPay is building a unified identity and KYC platform that can support customers across ramps, cards, virtual accounts and enterprise products.

Today, many financial products treat identity as part of a single onboarding flow. We are building it as a reusable platform capability: a secure identity layer that allows customers to verify once, maintain control of their information and access different MoonPay-powered products without repeating the same journey each time.

This role will help define the architecture and technical direction of that platform. You will work across product, engineering, compliance and security to determine how identity is captured, verified, stored, linked and exposed safely through APIs and SDKs.

As a Staff Software Engineer, you will hold a hands-on technical position. The problem is not fully defined, and we are looking for someone who can shape the platform while building its most important components.

Must-have experience and skills

• Identity platform experience. You have built or owned production identity, KYC, authentication or customer-data infrastructure used across multiple products.

• Platform architecture. You have defined shared technical foundations rather than delivering only a single onboarding or login experience.

• Public APIs and SDKs. You have built interfaces used by external developers and understand stability, versioning, documentation and backwards compatibility.

• Sensitive data. You understand the security, privacy and operational requirements involved in storing and processing identity information.

• Systems thinking. You can reason across data models, verification providers, product workflows, compliance requirements and failure modes.

• Ambiguity and influence. You have taken a problem nobody had fully scoped, created a technical direction and brought multiple teams with you.

• Hands-on engineering. You continue to design, build, review and operate production systems rather than leading only through documents and meetings.

Nice-to-have experience

• Built identity or KYC infrastructure within payments, fintech, banking or another regulated environment.

• Experience with reusable verified identity, identity vaults or portable customer profiles.

• Experience with OAuth, OIDC, WebAuthn, passkeys, session management or account recovery.

• Built systems supporting consent, data residency, privacy requests and audit trails.

• Worked with multiple KYC, KYB or identity-verification providers.

• Experience building developer platforms for external partners.

• Familiarity with cryptocurrency, wallets or digital-asset products.

• Familiarity with our stack: TypeScript, Node.js, GCP, PostgreSQL, Redis and Kubernetes.
