Software Engineer III — Developer Portal

ID.me•Mountain View, CA

About The Position

ID.me is seeking a Software Engineer III to join the Developer Portal team. This team is responsible for building a self-service platform that allows organizations to quickly integrate with ID.me's identity proofing services. The Developer Portal aims to streamline the onboarding process, enabling customers and their developers to register applications, configure identity needs, test in a sandbox environment, and launch to production through a modern self-service experience. This role is backend-leaning full-stack, focusing on designing and building services, APIs, and data models for application registration, authorization, and developer-facing APIs. The role also involves working on the user-facing surfaces of these services using Next.js and React, taking features from API contract to database schema, deployment, and production operation. The engineer will own features end-to-end, coordinate across teams, and grow into technical ownership of the systems they build. Backend services are primarily Java (Spring Boot) with some legacy Ruby services, and the frontend is a micro-frontend platform using Next.js, React, and TypeScript. Previous Ruby experience is not required, as the company values engineers comfortable learning new technologies.

Requirements

Bachelor's degree in Computer Science, Engineering, or equivalent practical experience. [Less for PhD, Master's]
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.
Strong communication and collaboration skills, with experience partnering across Product, Design, and Engineering.

Nice To Haves

Has built developer experience as an explicit goal for example SDKs, API reference docs, quickstarts, sandbox or test environments, error messages and debugging surfaces, or self-serve onboarding flows and can speak to how it changed time-to-first-successful-integration for real external developers.
Experience building developer-facing platforms such as developer portals, API platforms, authentication platforms, cloud platforms, payments platforms, or other self-service developer experiences.
Experience with modern Java (21+) and Spring Boot in production codebases.
Experience with Ruby on Rails.
Experience with PostgreSQL specifically, including graph-like or highly relational data models.
Experience with Next.js, or with micro-frontend architectures such as Webpack Module Federation.
Experience with enterprise identity standards including OAuth 2.0, OpenID Connect, SAML 2.0, or SCIM.
Experience with relationship-based authorization systems such as SpiceDB, OpenFGA, or Zanzibar-inspired architectures.
Experience with policy engines such as OPA or Cedar.
Experience performing feature-flag-driven migrations in customer-facing production systems.
Experience with OpenAPI tooling, docs-as-code, or SDK generation.
Familiarity with identity verification, fraud prevention, KYC/AML, or regulated identity systems.
Working knowledge of NIST 800-63 IAL/AAL guidelines.
Familiarity with Google Cloud Platform and cloud-native application development.
Experience with observability platforms such as OpenTelemetry, Honeycomb, Prometheus, and Sentry.
Experience with automated testing frameworks such as Playwright, Jest, or Cypress.
Startup or high-growth company background.

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.
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.
