• You’ll be part of a high-growth company backed by top-tier investors.

Let’s make the invisible visible!

What will you do

• Act as the technical escalation point for regional service teams and distribution partners, resolving issues that require deeper system expertise.
• Deploy rapidly to customer sites across Europe, the US, and Asia to resolve critical system issues and minimize downtime.
• Support installation, commissioning, and qualification of our quantum sensing systems when required, working closely with our Munich-based engineering teams.
• Perform advanced troubleshooting, calibration, and repairs across optical, laser, mechanical, electronic, and software subsystems.
• Diagnose and resolve complex technical issues systematically, collaborating with Engineering and R&D when root causes go beyond service-level expertise.
• Work closely with Field Application Engineers, who focus on measurement execution and customer applications, to ensure a seamless customer experience.
• Support spare-parts planning and service logistics across the global installed base, ensuring critical parts are available for rapid response.
• Document service activities, technical findings, and root causes, feeding recurring issues and improvement opportunities back into Product Development.
• Build trusted relationships with customers and partners through clear technical communication and professional service in demanding semiconductor environments.
• Help establish and continuously improve our global service processes, including escalation workflows, maintenance procedures, troubleshooting guides, and technical documentation.

What is expected of you

• 5+ years of hands-on experience in field service, service support, or equipment engineering roles, ideally with semiconductor, optical, laser, inspection, or metrology equipment.
• A proven track record of resolving escalated or complex system issues that first-line service could not solve.
• Strong practical troubleshooting skills across complex electromechanical systems, ideally combining optics, lasers, precision mechanics, electronics, and control software.
• Experience working in semiconductor fabs, cleanrooms, or similarly demanding technical environments, with an understanding of relevant safety and operating procedures.
• Familiarity with laser safety and interlocked systems, or willingness to complete the necessary technical and safety qualifications.
• Experience with spare-parts management, service documentation, and ERP or service ticketing systems is an advantage.
• A structured, independent, and solution-oriented approach to technical challenges, especially under time pressure.
• Strong communication skills and a customer-focused mindset, with the ability to explain technical issues clearly and build trust with customers, partners, and internal teams.
• Willingness to travel internationally on a frequent basis, often at short notice, to support customers and partners across the US, Europe, and Asia.
• Fluency in English. Other languages (e.g. German, Mandarin, Korean) are a plus.
• A degree in Engineering, Physics, Mechatronics, or a related field, or equivalent technical training and relevant practical experience.

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.
• 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.

About us

QuantumDiamonds GmbH, headquartered in Munich, Germany, develops and manufactures semiconductor inspection systems based on quantum sensing. Spun out of the Technical University of Munich in 2022, the company uses nitrogen-vacancy centers in diamond to map electrical current with micrometer precision inside advanced 2.5D and 3D chip architectures. Nine of the world's ten largest semiconductor manufacturers are engaged with QuantumDiamonds, with systems deployed across Europe, the United States, and Asia. The company is investing €152 million to build the world's first production facility for quantum sensing-based semiconductor inspection tools, supported under the European Chips Act.
