🚀 We’re hiring at the Quantum Device Lab at ETH Zurich!

Are you passionate about micro- and nanofabrication and eager to advance the frontiers of quantum technology?

We are looking for a Cleanroom Fabrication Engineer (100%, Zurich, fixed-term) to join our interdisciplinary group at the Quantum Device Lab (@qudev), within the Department of Physics (@ETH_physics) and affiliated with the @ETHQuantumCntr at @ETH_en.
In this role, you will play a central part in scaling our superconducting quantum processor chips incorporating tens to hundreds of qubits as we push toward building large-scale, fault-tolerant quantum computers.

🔬 What You’ll Be Doing
As our Cleanroom Fabrication Engineer, you will bridge state-of-the-art semiconductor processing with cutting-edge quantum physics:
• Device Fabrication & Process Development: Execute and optimize micro- and nanofabrication runs while pioneering novel processing techniques—such as high-aspect-ratio Through-Silicon-Vias (TSVs) via deep reactive-ion etching (DRIE) and conformal thin-film deposition.
• Yield Improvement & Metrology: Establish rigorous process control and systematic inspection routines to continuously boost fabrication yield for complex quantum chips.
• Coherence Optimization: Work hand-in-hand with fabrication engineers and experimental physicists across our lab to evaluate how fabrication parameters directly impact qubit coherence metrics.
• World-Class Cleanroom Facilities: Utilize state-of-the-art infrastructure across three leading cleanrooms in the Zurich area:
– FIRST at ETH Hönggerberg: first.ethz.ch
– BRNC at IBM Research Rüschlikon: brnc.ethz.ch
– PICO at Paul Scherrer Institut (PSI) Villigen: psi.ch/en/lmn/cleanro…

🎯 Who We’re Looking For
• Education: Master’s degree (or PhD) in micro/nanofabrication, physics, materials science, electrical engineering, or a related field.
• Hands-on Cleanroom Background: Practical experience in lithography, dry/wet etching, thin-film deposition, and surface metrology.
• Mindset & Skills: Strong attention to detail, structured work habits, excellent teamwork, and fluency in English.

📍 Key Info & Application Link
📍 Location: Zurich, Switzerland
🏛 Lab & Dept: Quantum Device Lab (qudev.ethz.ch) | D-PHYS (phys.ethz.ch) | ETH Quantum Center (qc.ethz.ch)
❓ Inquiries: Direct position questions to @BesseJC (no applications via email).
📩 How to Apply: Applications are accepted exclusively through the ETH online portal: emea2.softfactors.com/job-opening/rg…
Help us build the next generation of scalable quantum computers—apply today or repost/tag someone in your network who would be a great fit! 🔬✨

That is exciting. I got to know Pieter-Jan Derks at the @IBM QEC summer school in Tarrytown some years ago.
That school produced a lot of great researchers in QEC.
Good luck with the startup.
Maybe we can run some of your tools on our QEC hardware.

Today, Walrus Computing is coming out of stealth. We’re on a mission to turn fault-tolerant quantum computers into engines of discovery. We build the software layer that makes them useful to anyone with a question worth asking.

Curious about developing #quantum communication hardware with #superconducting #circuits?

Interested in doing a PhD with a leading lab in quantum science and technology?

The Quantum Device Lab (@qudev, qudev.phys.ethz.ch) at the Department of Physics (@ETH_physics), ETH Zurich, member of the Quantum Center (@ETHQuantumCntr) and the @ETH Zürich - @psich_en Paul Scherrer Institut Quantum Computing Hub is looking for highly motivated Doctoral Students for the development of a superconducting qubit quantum network and research in quantum networking applications.

We have done the first experiments on quantum state transfer between qubits housed in different cryogenic systems (journals.aps.org/prl/abstract/1…), performed the first loophole-free Bell inequality violation with superconducting circuits (nature.com/articles/s4158…), and demonstrated the first repeated quantum error correction in the surface code (nature.com/articles/s4158…).

Advance quantum science with superconducting circuits. Join the team!
