The company's AI-driven platform, DriveWell Fusion, gathers sensor data from millions of IoT devices - including smartphones, proprietary Tags, connected vehicles, dashcams, and third-party devices - and fuses them with contextual data to create a unified view of vehicle and driver behavior. Auto insurers, automakers, commercial mobility companies, and the public sector use insights from CMT's platform to power risk assessment, safety, claims, and driver improvement programs. Headquartered in Cambridge, MA, with offices in Budapest, Chennai, Seattle, Tokyo, and Zagreb, CMT measures and protects tens of millions of drivers across the world every day.

This is a hands-on engineering role for someone who thrives in a fast-paced environment, mentors others, and brings a strong sense of ownership and curiosity. Your work will directly impact how users experience CMT's products and contribute to our mission of making roads safer around the world.
