Mechanical/Electronics Engineer for High-End Wireless Tattoo Pen Prototype

We’re looking for an experienced engineer to help develop a fully functional prototype of a high-end wireless tattoo pen with an integrated battery.

Key responsibilities:
• Design and implement an adjustable stroke system (externally accessible, no disassembly required)
• Select and integrate a high-performance brushless motor (4V–11V operating range, stable torque and speed)
• Integrate a long-lasting Li-ion battery with voltage controller and digital display
• Ensure seamless compatibility between mechanical and electronic components
• Collaborate with our 3D designer to align technical and aesthetic requirements

Requirements:
• Proven experience in designing compact or precision electronic devices
• Strong knowledge of brushless motors, Li-ion batteries, voltage regulation systems
• CAD proficiency and understanding of design for manufacturing (DFM) and compact assembly

Previous experience with tattoo devices, aesthetic, or medical-grade equipment is a big plus.

Competitive budget and potential for long-term collaboration.
