• Experience writing technical specifications and system requirements.
• Strong debugging and problem-solving skills.
• Excellent communication skills and ability to work independently.
  
   

Nice to Have
 

• Experience with connected medical, wellness, beauty-tech, or IoT devices.

• Team: You will be the sole engineer responsible for this project.
• Working Hours: Flexible, with occasional evening meetings (around 8:00–9:00 PM Israel time) with the US-based team.
