Mission

To support our continued growth, we are looking for a Product Manager to lead our Inertial Measurement Unit (IMU) product line for defense applications. This position sits at the heart of SBG’s fastest-growing segment, driven by rising defense budgets, the increasing use of electronic warfare, and emerging military doctrines such as saturation weapons and cost-asymmetric strategies. SBG’s compact and sovereign MEMS-based IMUs have proven to be highly competitive in this environment, offering an optimal balance of performance, SWaP, and cost.

In this role, you will operate at the intersection of technology and business, acting as half system engineer, half business driver. You will combine deep technical knowledge of IMUs and GNC systems with strategic product management responsibilities, working closely with senior leadership and C-level executives to shape product direction, identify market opportunities, and support programs with Tier-1 defense manufacturer. You will contribute directly to the development of our offerings for defense manufacturers, build technical expertise, define product strategy and roadmap, and support customers throughout evaluation and selection processes, including tenders and specific development programs.

This position will require travels, up to 25%.
