Job description

Planys is a deep-tech company developing mission-critical robotic and digital systems for defence and strategic infrastructure. The company designs and builds unmanned systems and advanced sensing solutions across underwater, maritime, and land domains, with a strong focus on naval, coast guard, and army applications. Planys is actively engaged in the development of Unmanned Underwater Vehicles (UUVs) ranging from small to extra-large platforms, along with ruggedised electronic and digital systems for armoured vehicles.

Leveraging its strong foundation in marine robotics, underwater inspection, and non-destructive evaluation (NDT), Planys integrates defence-grade electronics, sensing, and data analytics to deliver high-reliability systems suitable for harsh operational environments. The company combines platform engineering, payload integration, and AI-enabled digital analytics to support situational awareness, asset integrity assessment, and data-driven decision-making for defence forces and strategic asset operators.

Planys, globally recognised for strategic infrastructure solutions, is now focused on creating a strong and enduring presence in the defence sector, delivering indigenous unmanned and digital systems for the Army, Navy, and Coast Guard. (Website: www.planystech.com )
