We're seeking an experienced Senior Software Engineer to own our Identity & Access platform end to end. Kuku is one of India's largest content platforms. This platform is the front door every user signs in through and the gate every request is checked against — one of the highest trust, highest blast radius parts of the product. We're a lean team with high ownership, and this is a role for someone who wants a critical service to be genuinely theirs. The ideal candidate has deep, hands-on experience with authentication and authorization systems, sessions and tokens, and building secure, highly reliable backend infrastructure that stays up under load.
Key Responsibilities
Identity & Access Architecture & Development
Own the authentication and authorization platform end to end — design it, build it, run it, and improve it. It has to be secure and reliable above everything else.
Own how users sign in: multiple sign-in methods behind one clean, consistent interface, so the rest of the product has a single dependable way to authenticate users no matter how they arrive.
Own authorization — who is allowed to do what across services
Own the full life of sessions and tokens, from how they're issued and refreshed to how they're revoked.
Integrate and manage third-party sign-in and identity providers, single sign-on (SSO), and multi-factor authentication (MFA).
Systems Reliability & Scaling
Keep the platform rapid and always up — it sits on the critical path of every request.
Build robust auth pipelines with monitoring, alerting, and fallback mechanisms.
Own production issues on the service end to end, from the alert to the fix to making sure it can't happen again.
Optimize backend services for performance, cost, observability, and reliability at consumer scale.
Security, Compliance & Governance
Keep the platform secure by default: how credentials are stored, how secrets are handled, and staying ahead of the usual ways identity systems get attacked.
