Identity Platform Engineer (OIDC / OAuth2)

Job Description

We're looking for an Identity Platform Engineer to support and enhance an enterprise OpenID Connect platform used across a large application ecosystem.

You'll work across application, platform, and infrastructure layers — investigating issues, onboarding clients, maintaining services, and improving how the platform runs day to day.

• Assist with client registrations, configuration changes, and onboarding
• Maintain Node.js and TypeScript services
• Support MFA integrations and identity federation
• Monitor platform health and respond to incidents
• Develop automation and operational tooling
• Support Elasticsearch and Redis-based services
• Participate in on-call rotations
