We are seeking a skilled mechanical or optical engineer to support the development and automation of our quantum sensing measurement systems. In this role, you will design and optimize high-stability components and motion assemblies that enable sub-micron positioning and reproducible measurements. You will work on high precision optics in both laser optics and the microscopy field. You will collaborate with a multidisciplinary engineering team, our engineering partners, and vendors to bring the first commercial generation of our precision instruments to market.

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 programmes, we have ensured long-term stability, shifting from breakthrough to scale - and shaping the next chapter in chip testing.

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 that loves solving hard problems and where knowledge flows fast.

Still unsure about why you should join 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!

• Design and construction of optical and/or mechanical units
• Conduct simulations, tolerance analysis, and testing to validate designs and ensure long-term stability and reproducibility.
• Collaborate closely with optical engineers, mechanical engineers, electronics engineers, and software developers to ensure seamless integration of mechanical systems into the full measurement workflow.
• Document designs, test results, and integration guidelines in a clear and structured manner.

• MSc degree with 4+ years of industry experience, or PhD with at least 3 years of industry experience.
• Minimum of 3 years of hands-on experience in design and construction
• Strong problem-solving skills and ability to work effectively in multidisciplinary teams.
• Structured working style with the ability to develop and manage modular, structured BOMs.
• Proficient in the use of CAD systems.
• Experience with the following topics is a strong plus: Radio frequency engineering, Zeemax, quantum physics, semiconductor tooling, system-level engineering

• 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.
• Learning & development: Your growth is our priority. We provide an annual budget dedicated to courses, conferences, or any resources that help you expand your skills.
• Ownership & participation: As part of our equity program, you’ll directly share in our success and the value we create together.
