UUV Simulation Engineer

About Heaviside Industries

Heaviside Industries builds multi-domain autonomous precision munitions for U.S. and allied special operations and conventional forces. While modern warfare has rapidly evolved with the proliferation of unmanned systems, hyper-precise munitions in contested environments are the future of the battlefield. Economical precision strike capabilities are critical to U.S. and allied war efforts, enabling successful defeat of enemy military assets and infrastructure. Heaviside builds precision munitions designed to operate in GPS-denied and spectrum-jammed battlefields—where traditional systems degrade or fail—without inflated prices or sacrifice to performance.

All engineering and manufacturing is conducted in-house in Heaviside’s Los Angeles, CA headquarters and Oslo, Norway office.

Heaviside is backed by Interlagos, Menlo Ventures, Flume Ventures, Cantos, Anorak Ventures, and Ravelin Ventures.
