Hardware & Firmware Engineer (Contract) – V0 & V1 Pilots

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

We are seeking a hands-on Hardware & Firmware Engineer to support the build, integration, testing, and monitoring of V0 and V1 portable battery pilots for university-focused energy infrastructure in Nigeria. We are running early-stage pilots to validate hardware behaviour, firmware control, and operational workflows ahead of an institutional-scale deployment.

Role Overview This is a practical, early-stage engineering role focused on modifying and controlling portable power systems for real-world pilot use. The engineer will work closely with the founder to deliver safe, testable, and grant-ready V0 and V1 systems. This is not a factory NPI or mass-manufacturing role.

Hardware Responsibilities

• Reconfigure pre-built portable power stations for pilot use
• Integrate GSM/LTE modules for SIM-based tracking and control
• Implement hardware mechanisms for remote output shutdown
• Validate AC (230V Type-G) and DC output behaviour under load
• Test overload, low-battery, and fault shutdown behaviour
• Support safe enclosure modifications where required
• Prepare small batches (2 3 units for V0, ~10 units for V1)

Firmware Responsibilities

• Design and implement embedded firmware to manage device states (active, disabled, fault)
• Implement remote enable/disable of outputs while keeping tracking and telemetry powered
• Integrate GSM-based telemetry and handle intermittent connectivity
• Enforce firmware-level power, current, and thermal limits
• Implement safe shutdown and fail-safe behaviour for overload, low battery, and thermal events
• Ensure firmware resilience across power loss and reboot scenarios
• Maintain firmware versioning consistency across V0 and V1 units
• Implement lightweight logging for pilot metrics and fault analysis
• Document firmware logic, assumptions, and safety-critical behaviour

Bonus Skill (Not Mandatory) Operator Dashboard & Admin Tooling (Low-Code)

• Configure or integrate a simple operator dashboard (no consumer app)
• Display device status, state-of-charge, and fault states
• Enable basic operator actions (remote enable/disable, device flagging)
• Prefer low-code or lightweight tools (e.g. Retool, Appsmith, Supabase, Airtable)
• Support data export for pilot analysis and grant reporting
• Ensure usability under intermittent connectivity

This role does NOT require building a consumer mobile app or a full cloud backend platform.

Required Experience

• Strong hands-on embedded systems experience (ESP32, STM32, or similar)
• Experience with battery systems, inverters, or power electronics
• Experience integrating GSM/LTE modules
• Comfortable working with off-the-shelf hardware and early-stage prototypes
• Strong safety awareness and pragmatic engineering judgement

Not suitable for:

• App developers
• Factory/NPI specialists
• Pure PCB designers

Location & engagement

• EU-based contractors preferred
• Remote + hands-on build required
• Contract duration: ~12 to 16 weeks (possibly longer)
• Milestone-based delivery (V0 V1)

Rate guidance

• 50 70 / hour, depending on experience
• Milestone-based payments
• Paid technical test included

Why this is interesting

• Real-world constraints, not lab theory
• Direct founder collaboration
• Work feeds into grant-funded institutional scale-up
• Clear scope no endless roadmap creep

How to apply Send:

• A short intro & CV
• 1 2 examples of hands-on hardware / firmware work
• Your availability
