QuantumDiamonds
quantum-sensing systems that see electrical defects inside advanced 3D chips without breaking them apart
Last verified August 17, 2026 · Updated daily
What QuantumDiamonds is building
QuantumDiamonds builds semiconductor inspection systems that use nitrogen-vacancy centers in synthetic diamonds — atomic-scale defects that detect magnetic fields with extreme precision — to map electrical current inside advanced 2.5D and 3D chip packages. In effect, a microscope that sees electricity. As chips go denser and more three-dimensional, buried defects are increasingly invisible to conventional optical and e-beam tools; QD's first commercial system, QDm.1, does non-destructive 3D current imaging at the nanoscale, locating a defect's depth and position without destroying the package. Work that took weeks in specialized failure-analysis labs happens in minutes. Systems are deployed in the US and Taiwan, serial production is ramping in Munich, and the company says nine of the world's ten largest chipmakers are engaged.
Why this matters
Yield is the money problem in advanced packaging — a single percentage-point improvement can be worth millions per week on a high-volume device — and inspection incumbents (KLA, Applied Materials, Onto) are built around light and electron beams that can't see what QD's quantum sensing can. The geopolitical tailwind is real and funded: QD is the first startup approved for manufacturing funding under the European Chips Act, joining names like GlobalFoundries and Carl Zeiss, with €76M in non-dilutive federal and Bavarian money. World Fund's managing partner is explicitly pitching it as Europe's next ASML in a $104B equipment market. Founders Kevin Berghoff (CEO) and Dr. Fleming Bruckmaier (CTO) spun the company out of TU Munich in 2022; its closest technical competitor, Qnami, was recently acquired, leaving QD alone in its lane at exactly the moment demand spikes.

250+Hiring outlook
The company states outright that it plans to more than double its engineering team within the next 12 months, from a base of 70 people — and it's simultaneously opening the first section of a large Munich production facility later this year. Doubling engineering while standing up serial manufacturing means sustained hiring across physics, hardware, software, and production roles, most of it in Munich, starting now.
Working at QuantumDiamonds
Since , QuantumDiamonds has built quantum-sensing systems that see electrical defects inside advanced 3D chips without breaking them apart. The team is now 50-200 people. For a Tech company this size, the reality is defined function but no bureaucracy, you'll own a surface area rather than a ticket queue.
Most openings are based out of Munich.
How to actually get hired at QuantumDiamonds
Why applying the normal way doesn't work
QuantumDiamonds runs an applicant tracking system, but hiring managers still work referrals first. A cold application to QuantumDiamonds isn't dead, it's just fourth in line behind internal referrals, sourced candidates and recruiter pipelines.
Who to contact at QuantumDiamonds
What to show them
Standing up or scaling production of complex hardware — process definition, supply chain for precision components, test and calibration lines. Experience commissioning a new production facility is the exact shape of the next 12 months here. Core skills: NPI, production ramp, quality systems, supplier management.
A cold email that works at QuantumDiamonds
What QuantumDiamonds screens for
A stated commitment to more than double engineering within 12 months, from a 70-person base, with a Munich factory opening this year and effectively no direct competitor left standing. That's structural, sustained hiring demand announced in one press release — and because it's Munich deep tech, global candidates aren't looking.

Don't make these mistakes
Don't pitch quantum computing — this is quantum sensing, a different discipline with shipping commercial hardware, and conflating the two signals you didn't do the reading. And don't undersell manufacturing: the next 18 months are about serial production and fab-grade reliability, not lab demos.
Mistakes that kill QuantumDiamonds applications
A recycled CV gets rejected fast at QuantumDiamonds (50-200 people). They notice.
Skip 'I'm looking for...' — start with Yield is the money problem in advanced packaging — a single percentage-point improvement can be worth millions per week on a high-volume device — and inspection incumbents (KLA, Applied Materials, Onto) are built around light and electron beams that can't see what QD's quantum sensing can and your specific angle on solving it.
The wait-and-hope strategy fails. Follow up on day five — response rates roughly double.
