Preferred Qualifications Frontend and developer experience * Has built developer experience as an explicit goal (SDKs, API reference docs, quickstarts, sandbox or test environments, error messages and debugging surfaces, 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, or payments platforms. * Experience with micro-frontend architectures such as Webpack Module Federation. * Experience with design systems, Storybook, or visual regression testing. * Experience performing feature-flag-driven migrations in customer-facing production systems. * Experience with observability tools such as OpenTelemetry, Honeycomb, Prometheus, and Sentry. Backend and platform (nice to have) * Experience building backend services and REST APIs with Java (21+) and Spring Boot, or Ruby on Rails, Node.js, or similar. * Experience with PostgreSQL, including authoring SQL and performing safe schema migrations. * Experience with OpenAPI tooling, docs-as-code, or SDK generation. * Experience with enterprise identity standards including SAML 2.0 or SCIM. * Experience with relationship-based authorization systems such as SpiceDB, OpenFGA, or policy engines such as OPA or Cedar. * Familiarity with identity verification, fraud prevention, KYC/AML, or regulated identity systems, and working knowledge of NIST 800-63 IAL/AAL guidelines. * Familiarity with Google Cloud Platform and cloud-native application development. * Startup or high-growth company background. ## Description 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 frontend-focused full-stack role. You will spend most of your time designing and building the customer-facing experiences of the developer portal: application registration, identity configuration, sandbox testing, and launch workflows, in our Next.js, React, and TypeScript micro-frontend platform. You'll care about usability, accessibility, performance, and a coherent design system. You'll also work with our backend teams on the API contracts behind those experiences, and contribute to backend services when it helps you ship a feature end-to-end. Backend experience is a plus, not a requirement. You'll own features from design handoff through production operation. You'll take defined problems, coordinate across teams to land them safely, and grow into technical ownership of the experiences you build. Our frontend is a micro-frontend platform built with Next.js, React, and TypeScript. Backend services are primarily Java (Spring Boot) alongside legacy Ruby services. We value engineers who are comfortable learning whatever technology the problem requires., Design and implement Developer Portal capabilities in Next.js, React, and TypeScript, from design handoff through deployment. Independently drive small-to-medium features, coordinating with adjacent teams where your work crosses service boundaries., Consume and help shape the REST API contracts behind your features. Our customers integrate directly against these contracts, so changes must be additive and safe by default. Contribute to backend services and data models where a feature requires it., Build secure, customer-facing flows spanning OAuth 2.0, OpenID Connect, enterprise SSO, multi-tenant access control, session handling, and credential management. Partner with our Identity, Organizations, Authorization, and Platform Engineering teams to evolve these capabilities without disrupting existing integrations.
