Electronic Hardware Design Engineer

We're looking for a Hardware Engineer who thrives in both deep-tech hardware engineering and hands-on rapid-prototyping in a fast paced startup-environment.

You'll take or come up with ideas and translate them into testable prototypes that will then mature into series products - translating system needs into schematics, designing and verifying PCBs, and ensuring your designs integrate seamlessly with mechanical and production aspects of our hardware.

This role bridges design, testing, and implementation - ideal for someone who enjoys both engineering rigor and practical problem-solving.

• Analyze system and functional requirements, and translate them into hardware specifications and testable PCB designs
• Develop schematics and layouts using modern EDA tools
• Collaborate closely with mechanical design, production, and operations teams to ensure smooth integration and manufacturability
• Build, bring-up, and debug hardware prototypes in the lab
• Support test development and automation, ideally using Python or similar scripting tools
• Participate in design reviews, documentation, and continuous improvement of design and validation processes

• Degree in Electrical Engineering, Electronics, or a related field
• Strong understanding of analog and digital circuit design, PCB layout principles, and component selection
• Experience in schematic capture and PCB design tools (e.g., Altium, KiCad, or similar)
• Knowledge about EMC and experience with best practices
• Comfortable with lab instrumentation (oscilloscopes, power supplies, signal analyzers)
• Hands-on attitude - you enjoy building, testing, and iterating quickly
• Basic programming experience in Python (or willingness to learn) for test automation and data analysis
• Strong communication and collaboration skills across disciplines

Nice to Have:

• Touchpoints with EMC measurement and debugging
• Experience with design-for-manufacturing (DFM) or end-of-line testing
• Familiarity with embedded systems or firmware basics
• Experience working in an agile or R&D-heavy startup environment
