Senior Software Engineer - Identity & Access

About the role

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.

What you'll do

• 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).
• Keep the platform fast 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.

What they're looking for

• 4, 6 years in backend engineering, with real production experience, not just side projects.
• Strong Python, with production experience in Django and Django REST Framework.
• You've designed and owned a critical backend service in production, ideally authentication or authorization or something with a similar blast radius. You've built the internals yourself.
• A solid grasp of how sign-in, sessions, and access control actually work under the hood.
• A security-first instinct: you think about how something gets abused or breaks, not just how it works.
• Comfortable owning data that has to be both correct and fast, across PostgreSQL, Redis, and ClickHouse.
• You can pick up an unfamiliar live system, understand it deeply, and change it safely without disrupting the people already using it.

Nice to have

• Experience integrating third-party sign-in and identity providers.
• Familiarity with single sign-on (SSO) and multi-factor authentication (MFA).
• Exposure to message queues and background task processing, such as Celery.
• Experience running a high-traffic, low-latency service where downtime is a company-wide problem.
• Prior work in a consumer product at real scale.
• Backend: Python (Django / Django REST Framework)
