Unless a specific job description explicitly states otherwise, all roles are on-site five days per week at one of our offices in McLean, VA; Mountain View, CA; New York City, NY; or Tampa, FL. Certain roles — such as field-based sales or other remote-by-design positions — may have different work arrangements as noted in their individual postings. At ID.me, we embrace the thoughtful use of AI tools in our daily work and there are even occasions where we leverage AI in our hiring process. However, during the interview process, we want to understand your individual skills and experiences. Therefore, we have guidelines on how AI can be appropriately used during your application and interviews which can be found here . Role Overview ID.me is seeking a Software Engineer III to join the Developer Portal team, where we're building the self-service platform that enables organizations to rapidly integrate id.me Identity proofing is fundamentally complex. Integrating an identity proofing flow requires many steps while meeting standards-body assurance requirements. The Developer Portal is the product that brings those pieces together for the external developer. Today, much of that onboarding is still performed manually by in-house Solutions Consultants who have many other responsibilities. Our mission is to enable customers and their developers to register their application, configure their identity needs, test in a production-like sandbox, and launch to production all through a modern self-service experience. This is a backend-leaning full-stack role . You will spend most of your time designing and building the services, APIs, and data models behind the portal — application registration, authorization, and the developer-facing APIs our customers integrate against. You'll also ship the user-facing surfaces of those services power, working in our Next.js and React frontend to take features all the way to the customer rather than handing them off at the API boundary. You'll own features end-to-end: from API contract through database schema, deployment, and production operation. You'll take defined problems, coordinate across teams to land them safely, and grow into technical ownership of the systems you build. Our backend services are primarily Java (Spring Boot) alongside legacy Ruby services powering identity, organizations, applications, and authorization. The frontend is a micro-frontend platform built with Next.js , React , and TypeScript . Previous Ruby experience is welcome but not required — we value engineers who are comfortable learning whatever technology the problem requires. This position is based in our Mountain View, CA office five days per week. Key Responsibilities Build & Ship Self-Service Developer Features Design and implement Developer Portal capabilities end-to-end — from API contract design through database schema, frontend integration, and deployment. Independently drive small-to-medium features, coordinating with adjacent teams where your work crosses service boundaries. Own API Contracts & Data Models Own the data models and REST API contracts for the capabilities you build, making deliberate decisions about backwards compatibility and versioning. Our customers integrate directly against these contracts, so changes must be additive and safe by default. Authentication, Authorization & Identity 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. Partner with our Identity, Organizations, Authorization, and Platform Engineering teams to evolve these capabilities without disrupting existing integrations. Cross-Functional Collaboration Partner with Product, Design, Architecture, and platform teams to clarify requirements, surface risks early, and keep the developer experience coherent as the platform grows. Required 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. [Less for PhD, Master's] 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
