Senior EMI/EMC Engineer (m/f/d)

Quantum Systems specialises in the development, design, and production of small Unmanned Aerial Systems (sUAS). The company's range of electric vertical take-off and landing (eVTOL) sUAS are built to maximize range and versatility and to provide operators with a seamless user experience. By integrating cutting-edge software capabilities, like edge computing and real-time AI-powered data processing, Quantum Systems is building next-generation UAS for clients in defence, security, public sectors.

As EMI/EMC Engineer you will will perform design, analysis and testing tasks for unmanned air vehicle systems down to a subcomponent system level. Furthermore, you will support in finding solutions for real-world problems related to jamming and electronic warfare. You will lead efforts in identifying and mitigating EMI/EMC vulnerabilities, supporting product compliance, and designing reliable hardware for mission-critical applications. You will also support in expanding our testing capability by planning and procuring test equipment according to our needs.

• Conduct hands-on debugging and mitigation of EMI/EMC issues at the board and system level using lab tools such as spectrum analyzers, LISNs, and near-field probes.
• Analyze and improve system susceptibility performance, ensuring immunity to field strengths of 50 V/m or higher across key frequency ranges.
• Design and implement RF filtering, shielding, and layout practices to enhance resistance to GPS jamming and spoofing.
• Collaborate with RF, digital, and systems engineers to review schematics and PCB layouts for EMC, GPS integrity, and radiation resilience.
• Perform and support lab testing campaigns for emissions, immunity, and GPS jamming resilience using MIL-STD-461, DO-160, or other standards.
• Select, evaluate, and qualify radiation-hardened components, ensuring suitability for TID and SEE environments, especially for aerospace or spaceborne systems.
• Develop and maintain internal design guidelines and checklists for EMC best practices, GPS robustness, and radiation mitigation techniques.
• Work with simulation tools (e.g., SPICE, HFSS, CST) to model EMI paths, coupling mechanisms, or radiation susceptibility.
• Participate in failure analysis and root-cause investigations when GPS lock is lost or EMI-related issues affect system functionality.
• Provide technical input during design reviews and collaborate cross-functionally to ensure the system meets reliability, compliance, and survivability goals.

• Bachelor's or Master's degree in Electrical Engineering, Physics, or related field.
• 3+ years of experience in EMI/EMC engineering, preferably in aerospace, defense, or high-reliability sectors.
• Proven experience with GPS signal resilience, including anti-jam antenna techniques and RF filtering.
• Hands-on experience with EMI/EMC testing tools and techniques.
• Ability to provide detailed EMI/EMC and EME design guidance.
• Perform testing in accordance with MIL-STD-461C/D/E/F/G, CISPR, FCC, DO-160.

• We believe in the power of combined efforts: straightforward tech expertise paired with a customer-centric focus.
• We are industry pioneers who are ambitious, bold, and visionary.
• We push limits, think outside-the-box and strive for technological excellence to shape the future of aerial data.
• We promise to be your runway for individual and professional growth.
