ID.me; Mountain View (CA); On-site; USD 173,000 - 193,000; Full time

Job summary

ID.me, based in Mountain View, CA, seeks a Software Engineer III for the Developer Portal. You’ll design and build backend services and REST APIs, work with Java Spring Boot, Ruby, Node.js, and frontend in Next.js/React/TypeScript, and own features end-to-end from API contracts to production deployment.

You will collaborate across Product, Design, Architecture, and Platform Engineering to deliver secure, scalable self-service onboarding for developers integrating with id.me.

Qualifications

• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience.
• 4+ years of professional software development experience building and operating production backend services.
• Strong experience building backend services and REST APIs using a modern web framework such as Java (Spring Boot), Ruby on Rails, Node.js, or similar.
• Deep experience with relational databases, including authoring complex SQL and performing safe schema migrations against production systems.
• Experience designing REST API contracts, including versioning and backwards compatibility, and documenting them with OpenAPI or a similar specification.
• Working proficiency with TypeScript and React — comfortable shipping customer-facing features through a modern frontend without requiring a frontend specialist to finish the work.
• Working familiarity with authentication and authorization concepts such as OAuth 2.0, OpenID Connect, or related identity standards.
• Demonstrated experience independently driving small-to-medium technical initiatives from definition through production, including cross-team coordination.
• Proficiency with AI-assisted development tooling (e.g., Claude Code, Cursor) and a commitment to an AI-first engineering culture that leverages these tools to improve software quality, testing, and engineering velocity.

Responsibilities

• Build secure Developer Portal capabilities spanning OAuth 2.0, OpenID Connect, enterprise SSO, multi-tenant authorization, relationship-based access control, session management, credential management, and identity-aware application provisioning.
• Design and implement Developer Portal capabilities end-to-end — from API contract design through database schema, frontend integration, and deployment.
• Own the data models and REST API contracts for the capabilities you build, making deliberate decisions about backwards compatibility and versioning.
• Partner with Product, Design, Architecture, and platform teams to clarify requirements and keep the developer experience coherent as the platform grows.
