About L3HARRIS WESCAM
As a subsidiary of L3Harris Technologies and within the Integrated Mission Systems Segment, the WESCAM division develops the most advanced optical sensor and targeting systems for global defense and military sectors, National Security, Search & Rescue and Airborne law enforcement agencies. From long‑range covert surveillance missions to search and rescue operations, our MX‑series systems, and the mission systems solutions they are a part of, produce stabilized high‑magnification electro‑optical and infrared images from airborne, marine and ground based platforms, enabling our customers to see first and act first.
The Software Engineering department at WESCAM is looking for an enthusiastic and motived new team member. Our software teams work directly with our optics and hardware teams, developing code that manages all of our systems controllers and actuators,



telephoto lenses or targeting & tracking systems. We develop advanced real‑time software for various applications and processors, including new payloads like complex imagers, laser illuminators & targeting designators, range finders and trackers. We develop the embedded controls and user interfaces for complex electro‑mechanical systems including remote I/O subsystems, custom lens controllers, and advanced video processing features.
Software at WESCAM is the heart of our MX‑series systems and the glue that pulls together state of the art mechanical, electrical and optical features of our designs. Each system and mission offers unique challenges so our software has to be flexible while meeting challenging performance requirements that push the boundaries of what is possible with advanced imaging systems. Come join the team and help us create the next generation of MX‑series systems
