HESS AG manufactures electric buses and trolleybuses at scale—around 2,400 units annually across five continents—while operating a full lifecycle business spanning repairs, spare parts, and fleet monitoring. The tech stack reflects a manufacturing-heavy organization: CODESYS and MATLAB for embedded systems design, CAN for vehicle networking, and recently cloud-based vehicle data processing. Current hiring pressure is manufacturing-focused (27 of 47 open roles), with engineering and operations roles trailing, suggesting production ramp-up is outpacing engineering iteration.
