Senior Backend Engineer

We’re building a platform to empower our customers using Spatial Intelligence. The backend platform is responsible for ingesting sensor and processed data from a distributed fleet of IoT systems installed on customer sites. The multi-dimensional data (video, metadata, audio, telemetry, and more) will be stored, processed, and made available using different APIs on the backend. Analytics will be computed in the backend and exposed via APIs and a web application. The platform needs to scale to support adding more clients and lines of business, and supporting large amounts of processed data.

COMPANY DESCRIPTION

We’re a team of industry veterans joining forces to address the most fundamental problems in machine perception and sensor fusion. We’ve built a new disruptive Tagless Activity Tracking platform, with roots in academic research, to revolutionize the world of industrial automation.
