Staff Software Engineer, Identity Platform

The role

Design and build a unified identity and KYC platform that supports MoonPay's ramps, cards, virtual accounts and enterprise products. You will help set the architecture and technical direction and build its key components as a hands-on staff engineer.

What you will do

• Turn a broad identity and KYC vision into a clear technical strategy, architecture and sequence of deliverable work.
• Identify the 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.
• Design a unified identity layer that supports multiple MoonPay products, partners and regulated use cases.
• Model the lifecycle of customer identity: creation, verification, linking, updates, consent and deletion.
• Build secure APIs and SDKs for internal teams and external partners.
• Integrate KYC and identity-verification providers while keeping MoonPay's internal model consistent.
• Define how identity data is stored, accessed and shared across products, jurisdictions and legal entities.
• Build public-facing APIs, SDKs and documentation with stable contracts, versioning and migration paths.

Required qualifications

• Identity platform experience: built or owned production identity, KYC, authentication or customer-data infrastructure used across multiple products.
• Platform architecture: defined shared technical foundations, not only a single onboarding or login experience.
• Public APIs and SDKs: built interfaces used by external developers; understands stability, versioning, documentation and backwards compatibility.
• Sensitive data: understands the security, privacy and operational requirements of storing and processing identity information.
• Systems thinking: can reason across data models, verification providers, product workflows, compliance requirements and failure modes.
• Ambiguity and influence: has taken a problem nobody had fully scoped, created a technical direction and brought multiple teams along.
• Hands-on engineering: continues to design, build, review and operate production systems.

Nice to have

• Built identity or KYC infrastructure in 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 TypeScript, Node.js, GCP, PostgreSQL, Redis and Kubernetes.
