Energy Hub: 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
