Software Engineer - IAM (OIDC/OAuth)

We're looking for a Software Engineer with Identity and Access Management (IAM) domain experience to support and enhance an enterprise OpenID Connect platform used across a large application ecosystem.

This is primarily an application engineering role, not a Kubernetes, DevOps, SRE, or infrastructure engineering position. You'll work on the identity platform itself. Investigating authentication and authorization issues, onboarding applications, maintaining Node.js/TypeScript services, implementing platform enhancements, and troubleshooting complex OAuth2 and OpenID Connect workflows.

The ideal candidate has hands-on experience building, supporting, or extending identity platforms and a strong understanding of OAuth2, OpenID Connect, JWTs, claims, scopes, MFA, and identity federation. You should be comfortable reading and modifying application code, debugging production issues, and diagnosing problems across application, data, and infrastructure layers.

This role operates with core collaboration hours of 6:00 PM – 12:00 AM IST to provide overlap with global teams. Outside of core hours, work is flexible and outcome-focused.

What you'll do

• Support day-to-day operation of the OIDC platform

• Investigate authentication and authorization issues

• 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
