BOLD Tech Stack

Battery and EV engineering for aerospace, marine, and automotive

Appliances, Electrical, and Electronics Manufacturing Montmelo, Barcelona 51–200 employees Founded 2019 Privately Held

BOLD designs and manufactures high-performance battery packs and complex vehicle engineering solutions for aerospace, marine, and automotive OEMs. The stack—CATIA, Siemens NX, CANoe, MATLAB, Simulink, plus Python/C++—reflects a heavy mechanical and electrical engineering operation. The project list (composite structures, chassis design, battery mechanical design, wind-tunnel testing, prototype builds) confirms they're shipping finished hardware, not software; hiring velocity is decelerating despite 23 open roles, with engineering dominating the team and recruitment of specialized technical profiles cited as a pain point.
