Engineering Open

As a PCB Engineer, you will design and layout the physical heart of our communication systems, integrating complex RF chains and high-speed digital processing into size-constrained, mass-producible modules. You will bridge the gap between theoretical schematics and battlefield-ready hardware, ensuring signal integrity, thermal management, and manufacturability under strict timelines.

About the role

As a PCB Engineer, you will design and lay out the physical heart of our communication systems, integrating complex RF chains and high-speed digital processing into size-constrained, mass-producible modules. You will take ownership from component selection to the final Gerber files and lab bring-up.

What you'll do

• End-to-end design: Lead the schematic capture and layout of complex multi-layer PCBs (HDI, rigid, and rigid-flex) involving high-speed digital interfaces and sensitive RF circuits.

• Signal & power integrity: Collaborate with RF and system engineers to implement impedance control, stack-up design, and shielding strategies to ensure optimal performance in noisy environments.

• Design for manufacturing (DFM): Work directly with fabrication and assembly houses to ensure designs are mass-producible and cost-effective without compromising quality.

• Component management: Select critical components with a focus on supply chain availability (preventing obsolescence) and environmental resilience (temperature, vibration).

• Lab verification: Support board bring-up, debugging, and electrical validation using oscilloscopes, VNAs, and spectrum analysers.

What we're looking for

• Bachelor's degree in electrical engineering, electronics, or a related field.

• 3+ years of professional experience in PCB design and hardware development.

• Proficiency with industry-standard EDA tools (Altium Designer preferred).

• Experience with high-speed digital layout (e.g. DDR memory, PCIe, Gigabit Ethernet) and mixed-signal design.

• Solid understanding of EMI/EMC principles and layout techniques to minimise interference.

• Professional fluency in German & English.

Bonus: not required

• Master's degree in electrical engineering.

• 5+ years of experience in hardware design for aerospace, defence, or automotive sectors.

• Deep expertise in RF layout techniques (microstrip/stripline, antenna integration, matching networks) up to 6GHz+.

• Knowledge of thermal management techniques for compact, high-power electronics.

• Experience with regulatory compliance testing (CE, FCC, MIL-STD-461).

• Strong teamwork skills combined with the ability to work autonomously as an individual contributor.

• Ability to meet tough goals under high pressure and manage time effectively.

How the hiring process works

1. Intro call. 30 minutes with our recruiting team. We'll learn about your background, and you'll learn about the mission.
2. Deep dive. A working session with one of our PCB/RF engineers on a real layout or signal-integrity problem.
3. Case study, in Dortmund or Munich. A visit to the office to walk through a board design case study with the team, in person if you can make it or over Teams if you can't.
4. The offer. By now you've likely already met our CEO. This round is where we make it official: fast, transparent, and built around the mission.
