About the Role

Build and scale the Shopping Graph backend APIs powering merchant onboarding and identity-gated commerce.

ID.me is the next-generation digital identity wallet that simplifies how individuals securely prove their identity online. Consumers can verify their identity with ID.me once and seamlessly login across websites without having to create a new login and verify their identity again. Over 152 million users experience streamlined login and identity verification with ID.me at 20 federal agencies, 45 state government agencies, and 70+ healthcare organizations. More than 600+ consumer brands use ID.me to verify communities and user segments to honor service and build more authentic relationships. ID.me's technology meets the federal standards for consumer authentication set by the Commerce Department and is approved as a NIST 800-63-3 IAL2 / AAL2 credential service provider by the Kantara Initiative. ID.me is committed to "No Identity Left Behind" to enable all people to have a secure digital identity.

ID.me is seeking a Senior Software Development Engineer to help design and build the next-generation SaaS Commerce Platform and Developer Ecosystem. The Shopping Graph team provides the primitives for merchant registration, identity-gated discounts, resource management, and policy enforcement—enabling both internal applications and external developers to build trusted, identity-powered commerce experiences.

As a Senior Engineer, you will be a key individual contributor implementing the APIs and backend services that power merchant onboarding, identity-gated offers, and OAuth 2.0 access flows. You will collaborate closely with Staff and Principal engineers to deliver scalable, secure, and developer-friendly APIs that form the foundation of ID.me's commerce ecosystem.

This role is based in our Mountain View, CA office, 5 days per week.

• Build reliable, well-tested backend services that support both internal applications and external developers.
• Contribute to an API-first, platform-first codebase ensuring services are scalable, extensible, and secure.

Developer Experience

• Partner with the Developer Experience team to deliver intuitive onboarding flows for external merchants and developers.
• Write clear API documentation and contribute to developer-facing resources that enable easy integration.

Cross-Functional Collaboration

• Work with the Authentication Platform, Organization Platform, Marketplace Apps, and Identity Graph teams to ensure consistency across ID.me's ecosystem.
• Drive adoption of best practices in distributed system design, observability, reliability engineering, and modern DevOps tooling.
• Participate in code reviews and contribute to team standards and engineering excellence.

Minimum Qualifications

• Bachelor's degree in Computer Science or related field.
• 6+ years of experience in backend software engineering, including API development for customer-facing products.
• 5+ years of experience in one or more modern languages such as Java, Ruby, Go, or Python, with experience building RESTful APIs and distributed systems.

Preferred Qualifications

• Strong understanding of API design, versioning strategies, and contract-first development practices.
• Familiarity with cloud platforms (e.g., AWS, GCP), infrastructure-as-code tools (e.g., Terraform), and modern CI/CD pipelines.
• Working knowledge of identity and access management standards such as OAuth 2.0, OpenID Connect, or SAML.
• Experience with monitoring, logging, and observability tools such as Prometheus, Datadog, or similar.
• Experience building high-reliability systems with a focus on performance, fault tolerance, and operational excellence.
• Exposure to multi-tenant SaaS architectures or identity-powered commerce platforms.
