Embedded Hardware Engineer for PI/TDEM Prototype

I’m looking for an electronics / embedded hardware engineer to help turn an existing PI/TDEM hardware design into a working, bench-tested prototype. The project is already substantially developed. I already have the engineering architecture, circuit concepts, component work, connection details, timing approach, and implementation planning. This is not a design-from-scratch project. I mainly need someone who can: - review the existing engineering package only as needed for implementation; - complete or correct schematic/PCB work where necessary; - prepare manufacturing files and BOM; - work with STM32 firmware and ADC acquisition; - handle pulsed MOSFET / inductive coil hardware; - assemble and bring up the prototype; - perform oscilloscope and LCR measurements; - debug the electronics; - bench-test the system and make necessary first-prototype corrections. Practical bench experience is important. Preferred experience: - PCB design and mixed-signal electronics - low-noise analog circuits - STM32 - power electronics / MOSFET switching - inductive loads or coils - ADC/data acquisition - hardware debugging and prototype testing The project is privately funded and the budget is limited, so I’m looking for a practical, cost-effective implementation partner rather than a large consultancy. Please provide your approximate engineering cost separately from components, PCB fabrication/assembly, and testing costs. I am based in London, but the final prototype is intended for Dubai, UAE. A future GPR module may be added later, but GPR development is not part of this initial project.
