MoonPay is building a unified identity and KYC platform to support customers across ramps, cards, virtual accounts, and enterprise products. Today, identity is often treated as part of a single onboarding flow. MoonPay is reimagining 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 verification journeys.
In this Staff Software Engineer role, you will hold a hands-on technical position helping define the architecture and technical direction of the identity 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.
Key responsibilities include:
**Lead through ambiguity:** Turn a broad identity and KYC vision into a clear technical strategy, architecture, and sequence of deliverable work. Identify boundaries between identity, authentication, verification, compliance, and product-specific onboarding. Set the technical bar through rigorous reviews, clear standards, and lasting engineering habits. Align teams across ramps, cards, virtual accounts, and enterprise products around a shared identity model.
**Build the identity platform:** Design a unified identity layer supporting multiple MoonPay products, partners, and regulated use cases. Model the lifecycle of a customer's identity, including creation, verification, linking, updates, consent, and deletion. Build secure APIs and SDKs allowing internal teams and external partners to use identity capabilities without understanding underlying complexity. Integrate KYC and identity-verification providers while keeping MoonPay's internal model consistent and extensible. Develop clear ownership boundaries between the identity platform and products built on top of it.
**Protect sensitive customer data:** Define how identity data is stored, accessed, and shared across products, jurisdictions, and legal entities. Design for consent, auditability, data residency, retention, and deletion from the beginning. Build clear authorization controls around who and what can access verified customer information. Ensure the platform degrades safely when external verification providers or internal dependencies fail. Partner closely with Security, Privacy, Legal, and Compliance without making the platform difficult for developers to use.
**Create a platform developers trust:** Build public-facing APIs, SDKs, and documentation that make complex identity workflows straightforward to integrate. Establish stable contracts, versioning strategies, and migration paths for teams and partners using the platform. Provide observability into identity journeys, verification decisions, and integration failures. Reduce the need for product teams to rebuild identity and KYC logic independently.

**Requirements:**
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 the stack: TypeScript, Node.js, GCP, PostgreSQL, Redis, and Kubernetes.
