Director of Engineering, Tern

Cyrus Behroozi

I lead engineering at Tern, where we build vehicle positioning that works when GPS does not.

I joined Tern in 2024 as a founding engineer. Today I lead engineering across the whole system: the positioning engine, the field app crews use, and the hardware inside the vehicle.

Before Tern I led the SDK team at Trueface, where our face recognition ranked #1 in the world for speed in NIST testing.

Positioning without GPS

Tern works out where a vehicle is from its own onboard sensors, on road and off. No satellites, no cell signal, no outside infrastructure, so it keeps working where GPS is jammed, spoofed, or simply gone.

A textbook illustration: a particle filter works out where a car is from its motion and a road map alone. Tern's system is different, and works off road too.

Positioning engine

Works out where a vehicle is from its own onboard sensors, on road or off, with no satellites, no cell signal, and no outside infrastructure.

Field app

Turn-by-turn navigation, mission planning, and TAK integration for crews, running fully offline on phones and tablets.

Vehicle interface

Plug-and-play hardware that connects to the vehicle and streams what the engine needs.
