Description We are seeking a motivated working student or intern to contribute to the development of next-generation quantum sensing hardware, with a focus on RF systems. You will assist in PCB design, assembly, and characterization of RF components, and support experimental measurements using our Quantum Microscope. As a RF Working Student / Intern you will be supporting daily lab operations, such as component logistics, system maintenance, and experiment setup. This position is ideal for someone interested in precision RF instrumentation and its applications in quantum sensing and semiconductor analysis, as well as gaining hands-on experience in experimental setup and measurements. Who we are Founded in 2022 as a spin-off of TU Munich, QD leverages quantum sensors to rapidly capture three-dimensional current maps within multi-layer chips. Our 30-strong team of physicists, engineers, and data scientists works side by side with major semiconductor manufacturers, helping them in chip debugging and accelerating their yield analysis. Backed by top-tier deep tech investors, semiconductor experts, and strategic public programs, we have ensured long-term stability, shifting from breakthrough to scale - and shaping the next chapter in chip testing. Why join us? Picture this: A machine that catches what others miss – in milliseconds. Physics, data, and engineering are working hand in hand to build tools that matter. An international team, who loves solving hard problems and where knowledge flows fast. Still unsure about why joining us? You'll get to build a company together with a brilliant and welcoming team on a product that has never been done before. Our technology is the cutting edge of tomorrow, starting today and not in 10 years. You will work directly with major semiconductor companies from Day 1. You'll get virtual shares and act on behalf of the entire company, beyond just your own team. You’ll be part of a high-growth company backed by top-tier investors. Let’s make the invisible visible! What will you do Join our team as an RF Working Student and contribute to the development and optimization of the RF subsystems that power our quantum diamond microscope - a cutting-edge instrument at the intersection of quantum technology and precision engineering. You’ll collaborate closely with our engineering and research teams to transform innovative RF designs into reliable, tested hardware. Your main tasks will include: Use lab instruments such as spectrum analyzers, VNAs, and oscilloscopes to characterize and debug RF components. Assist with schematic capture and PCB layout using tools like Fusion or Altium. Supporting lab experiments: Help set up and operate RF systems and participate in experiments involving the quantum microscope. Solder components What is expected of you We’re looking for a curious, proactive, and detail-oriented student who enjoys combining simulation, design, and hands-on experimentation in the lab. You should have: Education: Enrollment in a Bachelor’s or Master’s program in Electrical Engineering, Physics, or a related field. Technical skills: Familiarity with PCB design tools (Fusion or Altium); basic knowledge of RF measurements tool. Experience with simulation tools such as Ansys HFSS is a plus. Mindset: Analytical, organized, and eager to learn — with a structured approach to troubleshooting and problem-solving. Collaboration: Comfortable working in a multidisciplinary team alongside engineers and physicists. Language: Proficiency in English (German is a plus). Availability: Up to 20 hours per week, with flexibility during exam periods. Our benefits Mission: At QD, we’re driven by more than just building great products - we aim to make a lasting difference. Joining us means contributing to meaningful work that goes beyond business as usual. Impact & growth: This is an exciting stage of our journey, and your voice matters. You’ll have the chance to shape our culture, influence key decisions, and grow alongside a company that’s scaling fast. Well-being & balance: We value rest and recovery. That’s why you’ll enjoy 30 vacation days plus public holidays to recharge and return inspired. Health & fitness: With a company-sponsored Wellpass membership, you’ll have access to countless gyms, classes, and wellness offers across Germany to stay healthy and active. Team & culture: We believe the best ideas come when we connect outside the office. From regular off-sites to team events, you’ll be part of a collaborative and supportive environment.
