The main tasks will include:

• designing device architecture according to technical specifications;
• selecting components and circuit solutions;
• developing and simulating analog and digital circuits (LTSpice, Tina TI, or others);
• developing PCBs in Altium Designer (2–4 layers), configuring projects for production requirements, working with high-speed interfaces and impedance-controlled lines (50/100 Ohm);
• developing firmware for STM32 on CMSIS without using HAL as the main framework;
• working with Git (repositories, merge, access rights, Git LFS, gitignore).

We offer:

• the opportunity to propose and implement your own ideas that influence the product and its mass production;
• a place in a rapidly growing company with a motivated professional team;
