Title: Electrical Engineer Needed for Arduino Based Prototype Build (Enclosure Electronics)

Description:
We are seeking an experienced electrical engineer to support the design and build of a small prototype system using an Arduino. This is a real world product prototype that combines enclosure based electronics, basic sensing, control logic, and power management.

We already have a concept and a rough functional outline. Your role is to turn this into a practical, reliable build with clear documentation that we can iterate on.

Scope of work (high level):

Review our concept and propose a suitable architecture (Arduino)

Design the electrical system and component selection (BOM)

Power design (Preferably hard wired, not battery)

Integrate and control multiple modules (drivers, sensors, indicators, switches, etc.)

Produce wiring diagrams / schematics and a clean prototype wiring plan

Firmware support (basic control code, libraries, reliability, fail safes)

Guidance on enclosure integration (connectors, cable routing, heat considerations)

Debugging support and iteration during the prototype stage

Deliverables:

Simple system overview and recommended approach

Schematics/wiring diagrams (PDF + source files if possible)

Firmware/code repository or zipped project folder with notes

Build and test notes so we can reproduce the prototype

Required experience:

Strong electronics and microcontroller experience (Arduino, ESP32, STM32, etc.)

Power regulation and protection (fusing, reverse polarity, transient protection)

Experience with real world prototype builds (not just simulations)

Comfortable producing clear documentation and diagrams

Nice to have:

Experience with productisation (DFM, connector selection, serviceability)

EMC awareness and best practice grounding/wiring for noise reduction

Experience designing around heat management and compact enclosures
