Engineering & Architecture Engineering (Mechanical / Chemical / Civil / Electrical)



šŸ“ Project Brief (NDA-safe):

We need a skilled electronics engineer to develop a compact modular system that:


Measures current from multiple low-voltage nodes (1–100)


Dynamically groups them into series-connected sets using solid-state switches (MOSFETs or similar)


Routes each group through a buck converter to produce a regulated voltage (e.g., 12V)


Uses a microcontroller or FPGA to manage reconfiguration logic in real time


Key tasks:


Circuit design (sensing, switching, DC-DC regulation)


Component selection (MOSFETs, buck converter ICs, controller, sensors)


PCB layout (dual-sided, thermally stable)


Firmware (basic control logic for measuring and switching)


Skills required:


Analog/digital circuit design


Power electronics (buck converters)


Microcontroller or FPGA firmware


PCB layout and thermal design


Project is pre-NDA; purpose is confidential.
