Senior Backend Engineer (TypeScript + Node.js)

About Framna

At Framna, we partner with ambitious brands to build digital products that make a real impact. We work across the full product journey from strategy and UX to engineering and long-term growth, combining strong technical expertise with a product mindset.

Our culture is built on trust, ownership, and collaboration. We value open communication, continuous learning, and teams that take responsibility for what they build.

About the role & project

We are developing a next-generation biometric authentication platform safeguarding millions of transactions, engineering high-end backend services capable of real-time analysis at scale. As a Senior Backend Engineer (Node.js, TypeScript), you will hold full architectural ownership of mission-critical systems and directly shape the product.

While we foster an AI-driven delivery mindset, we place immense value on low-level engineering depth-knowing that true system resilience, performance, and bulletproof security demand a thorough understanding of what happens under the hood.

We follow a hybrid work model, with regular in-office syncs to stay aligned as a team.
