Job description

About Us

QuantWare is building the world’s most powerful quantum processors to solve humanity's greatest challenges. We do this with our unique VIO™ technology, the only QPU architecture that breaks the hardware barriers that have held quantum computing back, unlocking the path to MegaQubit quantum processors.

With VIO, we are paving the way for the hyper-scale quantum computers that will change the world. And delivering on that vision demands people who don’t shy away from tackling the hardest challenges of our time. That’s where you come in!

We are building a state-of-the-art fabrication facility dedicated to manufacturing quantum processors. As a Senior Process Engineer you will sit at the intersection of R&D and operations, translating cutting-edge quantum device research into repeatable, high-yielding processes.

You will play a central role in two critical phases of the fab ramp-up: (1) transferring processes from the R&D team into the kilofab environment through MES and optimizing them for yield, throughput, and repeatability; and (2) qualifying new capital equipment as it arrives on the fab floor through Site Acceptance Testing (SAT).

What you'll be doing

Tool Qualification & SAT

• Lead or co-lead Site Acceptance Testing (SAT; IQ/OQ/PQ) for incoming process tools (at least for 2 process modules).
• Create SAT criteria in collaboration with equipment engineers and tool vendors; Negotiate test conditions and results sign-off.
• Execute qualification wafer runs, analyze results, and generate formal SAT reports with pass/fail determinations.
• Manage your responsible tool installation timelines together with Facilities and Equipment Engineering to minimize schedule impact.
• Coordinate vendor support during tool bring-up and drive resolution of open issues to baseline release.

Process Transfer & Optimization

• Own the end-to-end transfer of at least 2 process modules (PVD, CVD, ALD, dry/wet etching, track, evaporation, dicing and laser/e-beam writing) from R&D to kilofab.
• Work closely with R&D scientists to ensure process intent is preserved during transfer and to feed learnings back upstream.
• Develop and execute process qualification plans (PQPs): establishing process windows, control limits, and acceptance criteria.
• Establish and maintain process control monitoring (SPC) for all processes and set up fault detection classification (FDC) with the fab automation team.
• Drive DOE (Design of Experiments) to optimize key process parameters for yield improvement.
• Use data driven decision making to perform root cause analysis to identify and resolve process issues.
• Document all learnings made in a structured way so these can form the basis of OCAPs in the future.
• Document SOPs and train technicians on tool operations and wafer level metrology.
• Own the process engineering scope within the MES: Manage recipe lifecycle (creation, revision, versioning, and retirement), maintain process and parameter data integrity to ensure traceability, deploy SPC, update process consumables & DOE creations.
• Participate in the Change Control Board (CCB): Provide relevant data for review and drive the approval for the change of process.
• Support the rapid introduction of new processes and products to match Quantware's fast-evolving product roadmap demands.
• Build respectful relationships across process engineering, process integration, R&D, Equipment Engineering, facilities and production teams to drive cross-functional alignment to achieve a win-win outcome.
• Proactively build and document deep hardware knowledge of responsible process tools, connecting tool mechanics to process behavior to drive informed optimization and faster troubleshooting.

Your Profile

• MSc or PhD in Physics, Materials Science, Electrical Engineering, Chemical Engineering, or a closely related discipline.
• 5-7 years of hands‑on cleanroom process engineering experience in a semiconductor fab or advanced materials fabrication environment.
• Demonstrated experience with at least two of the core process modules listed above (PVD, CVD, ALD, dry/wet etching, evaporation, dicing, track or laser/e‑beam writing).
• Practical experience executing or supporting equipment qualification or SAT activities.
• Proficiency in statistical analysis tools (JMP, Minitab, Python/R for DOE and SPC analysis).
• Strong documentation skills; experience writing SOPs, process & tool specifications, and qualification reports.
• Ability to work in a Class 100/ISO 5 (or equivalent) cleanroom environment.
• Experience in superconducting qubit fabrication, cryogenic device processing, or other quantum technology contexts is a bonus.
• Familiarity with cryogenic material constraints (e.g. film stress, thermal cycling behavior) is also desirable.
