Backend Engineer

Build the real-time backend behind millions of AI voice calls. Sub-500ms latency, zero dropped audio, and enterprise scale.

About Finn AI and The Role: Finn is the enterprise voice orchestration layer. We build AI agents that handle thousands of concurrent inbound and outbound calls—reasoning through them, extracting data, and updating CRMs in real-time. We are looking for a Backend Engineer to architect and scale the systems powering this platform. At Finn, every millisecond counts. You will build and optimize our core routing engines, webhook architectures, and API integrations that connect our AI to enterprise systems. If you love solving complex state-management problems and building resilient infrastructure that never drops a call, you belong here.

What You Will Do

In this role, you will architect and maintain backend services capable of managing thousands of simultaneous, real-time voice streams and LLM interactions.

You will be joining a high-talent, zero-BS culture focused on shipping great products, with a flexible remote work policy across the US and India, plus physical hubs in Bengaluru and Jaipur.
