About OM Defence Systems

‍

OM Defence Systems develops advanced drone and autonomy technologies for defence and security applications. Our mission is to build reliable, intelligent unmanned systems that integrate flight control, real-time communication, and AI-powered decision-making.

We are expanding our hardware engineering team in Berlin and looking for an Embedded Hardware Engineer to design and validate next-generation electronic systems for our unmanned platforms.
This role is suited for an engineer who works across the full hardware lifecycle, from circuit design and prototyping to testing and production support in a fast-moving R&D environment.

‍

What you’ll do

‍

• Design analog and digital circuits and develop high-quality schematics using Altium Designer or KiCad.
• Select electronic components, evaluate alternatives, and support PCB layout for manufacturability, reliability, and signal integrity.
• Develop and document cable harnesses, wiring diagrams, and system interconnects.
• Build, test, and debug hardware prototypes, troubleshooting issues at board and system level.
• Perform basic analyses and simulations including power distribution, signal integrity, and EMC/EMI considerations.
• Prepare and maintain engineering documentation such as schematics, BOMs, revision history, and fabrication notes.
• Collaborate with PCB manufacturers and assembly partners, assess capabilities, and support production-related discussions.
• Work closely with firmware, systems, and mechanical engineering teams throughout development and testing.
• Support hardware validation during lab and field testing of autonomous systems.
