Software Engineer - Backend (Product)

Ambient.ai is the category creator and leader in Agentic Physical Security. Powered by Ambient Pulsar, the first reasoning Vision-Language Model purpose-built for physical security, our platform seamlessly integrates with existing security cameras and physical access control systems to unify monitoring, access control, threat assessment, response, and investigations through an always-on reasoning layer that augments security operators with superhuman capabilities. The results: 95% fewer false alarms, investigations 20x faster, and 10x faster response.

The momentum speaks for itself: we doubled new ARR in FY26, we process 200M+ video hours per day, and have delivered results for world-class customers including Cisco, ServiceNow, SentinelOne, TikTok, Bayer, and MoMA. That kind of momentum creates an environment where great people thrive, and it shows: we recently ranked #71 out of 500 on the Forbes best startup employers list.

Founded in 2017 and backed by Andreessen Horowitz, Y Combinator, and Allegion Ventures, Ambient.ai is on a fast-paced journey to fulfill our mission: prevent every security incident possible.

You'll design and build the backend powering Ambient.ai's product experience for enterprise security teams. The APIs and services you ship are used directly by operators at Fortune 500 companies to monitor and respond to security events across tens of thousands of cameras.

You'll own a core product area end to end, partnering with frontend engineers, designers, and product managers to take features from concept to scaled production. Expect a mix of greenfield work on new product surfaces and depth work on systems already serving large enterprise deployments.
