Your Mission

As a Junior PCB & Electrical Systems Engineer, you will be responsible for the reliability, optimization, and development of our electronic hardware. You will transition existing prototypes into scalable, mass-production-ready designs, troubleshoot hardware failures, and take complete ownership of our cable and interconnect systems.

What you'll do

• Full-Cycle PCB Design: Transition from maintaining existing hardware to independently designing and developing new PCBs completely from scratch.
• Troubleshooting & Diagnostics: Utilize lab equipment (oscilloscopes, multimeters, thermal imaging) to diagnose, debug, and resolve complex hardware and signal integrity issues.
• Design for Manufacturing (DFM): Modify and optimize existing schematics and layouts to lower production costs, improve yield, and ensure readiness for mass production.
• Cable Systems Ownership: Take full responsibility for the design, connector selection, and routing of cable harnesses. You will ensure durability and signal integrity across all moving mechanical parts.
• Cross-Functional Collaboration: Partner closely with firmware, mechanical engineering, and operations teams to ensure seamless hardware integration.
• Professional Development: Actively participate in mentorship sessions and complete company-sponsored training courses to master specialized electrical engineering topics.

Your profile

• Education: Bachelor’s or Master’s degree in Electrical Engineering, Mechatronics, or a related technical discipline (or equivalent practical experience).
• Technical Fundamentals: Strong foundational knowledge of circuit design, component selection, and basic multi-layer PCB layout principles.
• Software Tools: Familiarity with standard PCB design software such as Altium Designer, KiCad, or Eagle.
• Problem-Solving Mindset: A structured, analytical approach to debugging hardware issues. You look beyond the immediate symptom to find the root cause of a failure.
• Drive and Motivation: An exceptional eagerness to learn, a proactive work ethic, and the ability to thrive in a fast-paced environment.
• Preferred Qualification: Prior experience or a strong personal interest in 3D printing systems, CNC machinery, or robotics is highly advantageous, though not strictly required.
• As a company specializing in both hardware and software, we value close collaboration within our team. Therefore, we are seeking candidates who can join us at our office in Hamburg.
