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

Energy Hub • Remote • 4w ago

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
