QPU Integration Engineer (Micro-Fabrication focused) (f/m/d)

Location: Hamburg, Germany; onsite

Company

hirify.global develops and operates full-stack quantum computers based on trapped-ion technology, combining laser-cooled trapped ions with microwave control and tailored magnetic fields.

What you will do

• Act as the technical expert for FEOL and BEOL fabrication modules, including lithography, thin-film deposition, etching, dielectric isolation, passivation, and interconnects.
• Lead end-to-end integration of multilayer QPU architectures and translate design requirements into manufacturable design rules and process design kits.
• Manage daily internal cleanroom fabrication, process baselines, run schedules, deviations, metrology, yield analysis, and design feedback.
• Lead R&D projects for new materials, geometries, and process steps, including process transfer and yield matching with external foundries and research institutes.
• Drive RCA, PFMEA, SPC, process-window definition, and failure resolution for integration issues and performance degradation.
• Mentor junior engineers and technicians and author process specifications, SOPs, and technical roadmaps.

Requirements

• Master’s or Ph.D. in Microelectronics, Electrical Engineering, Materials Science, Applied Physics, Nanotechnology, or a related field.
• At least 5 years, or equivalent extensive industry experience, in hands-on semiconductor or quantum hardware integration in a professional Class 10/100 or ISO 4–5 cleanroom.
• Deep FEOL and BEOL expertise, including e-beam or optical lithography, PVD/ALD thin films, RIE/DRIE, planarization, lift-off, and flip-chip or interconnect technologies.
• Experience taking complex solid-state micro/nano devices from R&D concept to stable, repeatable integration flows.
• Experience managing joint development projects or technology transfers with commercial foundries or external fabrication partners.
• Strong project management skills covering timelines, deliverables, and milestones.
• Knowledge of SPC, DOE, PFMEA, and structured RCA methods such as 8D and Fishbone.
• Proficiency with layout and data tools such as KLayout, Cadence, and Python or MATLAB for yield and parametric analysis.
• Fluent English, written and spoken, with excellent technical writing and presentation skills.

Nice to have

• Quantum hardware integration experience with superconducting circuits, trapped-ion traps, spin qubits, or photonic chips.
• Experience with low-loss dielectrics, superconducting interconnects, 3D integration, or TSV technologies.
• Experience establishing cleanroom process baselines or setting up new process lines and tools from scratch.
• Experience managing foundry contracts, IP considerations, and wafer delivery schedules.
