24V to 240V Converter Design with BMS

I need a skilled engineer to design a PCB and software for a portable device that converts DC 24V to 240V. The device should have an integrated battery charger and a Battery Management System (BMS) for LiFePO4 batteries.

Key requirements:
- 2kw output peak 4kw
- Low battery alert
- Re-charge from 240/110v (50/60hz)
- Solar input 200w max
- External battery
- Onboard BMS
- 24v battery input (lifopo4)
- Adjustable recharge rate from mains, 3kw max (when using 240v) 1.5kw max on 110v
- LCD screen for displaying:
o SOC
o Time to empty
o Time to full charge
o Current output
o Current input
- Bluetooth for
o Future use
o Firmware updates


Ideal skills and experience:
- Expertise in PCB design
- Experience with power electronics and converters
- Proficient in developing BMS
- Background in software development for embedded systems
- Knowledge of LiFePO4 battery systems

Please provide relevant work experience and a portfolio.
