Hardware and Firmware Engineer (Contract / Short-term (V0 & V1 pilots))

Headquarters: Lagos, Nigeria
URL: http://energyhubclub.com

We're running early-stage pilots (V0 and V1) to validate hardware behaviour, firmware control, and operational workflows ahead of an institutional-scale deployment.

We’re looking for a hands-on hardware & firmware engineer to help us modify, integrate, and test portable power systems during V0 and V1.

This is not a mass-manufacturing role. It is a prototype and pilot role focused on:

• hardware reconfiguration

• embedded firmware

• remote monitoring & control

• real-world testing

You will work directly with the founder to turn off-the-shelf components into a controlled, pilot-ready system.

Key Responsibilities

Hardware (V0 & V1)

• Reconfigure pre-built portable power stations (where feasible)

• Integrate:

  • GSM/LTE modules (SIM-based tracking, not Wi-Fi or Bluetooth)

  • GPS or location telemetry

  • External control relays / shutdown mechanisms

• Validate:

  • AC and DC output limits

  • Overload and low-battery shutdown behaviour

  • Safe charging via AC adapters and solar-assisted kiosks

• Support safe enclosure modifications where required

Required Experience:

• Strong experience with embedded systems (ESP32, STM32, or similar)

• Hands-on experience with battery systems, BMS, inverters, or power electronics

• Comfortable working with real hardware, not just simulations

• Experience integrating cellular (GSM/LTE) modules

• Ability to debug issues remotely and pragmatically

• Comfortable working in an early-stage, ambiguous environment

Nice-to-Have (Not Required)

• Experience with LiFePO₄ systems

• Experience with solar + MPPT controllers

• Prior work on IoT devices deployed in the field

• Experience with power systems in emerging markets

***Minimum 5 years experience

**** Europe-based prefered
