Electrical Engineer & 3D Product Designer for Plasma-Activated Water Machine (Aqua Lightning)
Project Overview
At Aqua Lightning, we are developing innovative technology in the field of Plasma-Activated Water (PAW). To turn our concept into a fully functional, market-ready product, we are looking for experienced freelancers for hardware engineering and product design.
This project consists of two key phases:
* Phase 1: Prototype Development – A design focused entirely on 3D printing and rapid assembly to physically test and validate the concept.
* Phase 2: Mass Production (DFM) – Once the prototype functions as expected, we will transition the design for injection molding and large-scale manufacturing.
We are seeking specialized expertise in two main areas:
Role 1: Electrical Engineer (Hardware Design)
Responsibilities:
* Design and develop the PCB/schematics for the plasma activation system (including high-voltage drive / power supply, pump control, and sensor integration).
* Select components to ensure a safe, efficient, and reliable hardware architecture.
* Deliver complete Gerber files, BOM (Bill of Materials), and schematics ready for PCB manufacturing.
Role 2: 3D Product Designer / Industrial Designer
Responsibilities:
* Design the outer enclosure and internal mechanical components (water inlet/routing, reaction chamber, mounting brackets).
* 3D Printing Optimization (Phase 1): The design must be optimized for 3D printing (FDM/SLA/SLS) to ensure easy fabrication with minimal post-processing.
* Ensure waterproofing/sealing, proper isolation around electronics, and ease of assembly.
* DFM Preparation (Phase 2): Convert the validated prototype into a production-ready design suitable for injection molding.
Desired Skills & Experience
* For Electrical Engineers: Proficiency in PCB design tools (Altium, KiCad, EasyEDA); experience with power electronics, high-voltage/frequency control, or plasma applications is a major plus.
* For 3D Designers: Proficiency in CAD software (SolidWorks, Fusion 360, Rhino); expertise in Design for Additive Manufacturing (DFAM), waterproof mechanical enclosures, and DFM.
* Strong communication skills in English.
How to Apply
When submitting your proposal, please include:
* Which role you are applying for (Electrical Engineer or 3D Designer) — Combined proposals from small teams or agencies are also welcome!
* Relevant portfolio examples of similar past projects (electronic enclosures, 3D-printable prototypes, or custom PCB designs).
* The CAD / PCB software you use.
* Your hourly rate or an estimated fixed budget for Phase 1.
