Cleanroom Lithography Equipment & Production Engineer H/F

The role

We've just built a cleanroom in Aubervilliers dedicated to the fabrication of superconducting quantum devices — a step change in our wafer capacity and in how fast we can iterate on qubit designs. The Cleanroom Operations team, created now, owns the throughput of that line.

You join as a Tool Owner and hands-on production engineer on the lithography scope: electron-beam and laser lithography, resist processing — coating, bake, development, stripping — and wet processing. It's the scope with the highest number of process steps in the flow and the tightest coupling to cycle time; when it slips, everything slips.

You're accountable for a defined set of tools: their uptime, their maintenance, their utilization, and the qualified recipes that run on them at industrial cadence. For each tool you form a binome with a Process Owner from Process Development Engineering — you own the asset and its execution, they own the recipe and its process window, and you solve the hard problems and qualify operators together. Recipe ownership and process innovation sit with them; making the tool deliver, reliably and at cadence, is yours.

You're joining a team at its creation, reporting to the Cleanroom Operations Manager. You'll build the operation rather than inherit one.

We're hiring two Tool Owners for this team, one on lithography and one on deposition and etching. If your experience spans both, apply to whichever fits best — we'll route you.

Responsabilities

• Working in Tandem — Partner with a Process Development Process Owner on each tool: they own the recipe and process window, you own making it run reliably and at cadence in production.
• Your tools — Keep your process equipment running: uptime, maintenance, troubleshooting, spares, and acting on drift before it turns into scrap. Cross-train at least two qualified operators per tool so none depends on a single person.
• Process transfer and control — Take each process from R&D to production: freeze the recipe, define spec limits, write the SOP, qualify operators and tools. Build control plans with your Process Owner, run SPC monitoring, conduct process FMEAs, and apply change control on qualified recipes.
• The weekly load plan — Turn the wafer launch plan into a tool-level plan, level the load across technicians, and flag early when output and plan diverge.
• Execution at cadence and quality — Run qualified recipes on experimental and test wafers, stop and escalate out-of-spec steps, decide on affected wafers with Process Development, and keep full MES traceability.
• Documentation & training — Write and improve SOPs, and qualify and train technicians alongside your Process Owner counterpart.
• Continuous improvement — Remove bottlenecks, track KPIs, contribute to failure analysis, and use process data to propose and validate improvements with your Process Owner.
• Safety — Apply cleanroom and equipment safety rules, and contribute to risk assessments, including for unattended and out-of-hours operation.
 
 
 
 

Requirements

3+ years hands-on in a semiconductor cleanroom, pilot line, or micro/nanofabrication facility, with direct equipment operation and maintenance experience (not just supervision)

Experience with process control in production/pilot-line settings (SPC, control plans, FMEA, or R&D-to-production transfer)

Preventive maintenance, troubleshooting, and supplier coordination on capital equipment

Solid grounding in semiconductor unit processes (deposition, lithography, etching, wet processing, metrology) and vacuum systems

Comfortable with production/equipment data (MES, spreadsheets, basic statistical analysis)

Experience building and reporting against a load plan under equipment, maintenance, and personnel constraints

Experience writing SOPs and training others on them

Strong ownership mindset, sound judgment to stop and escalate, and early, factual communication

Willingness to train on and back up tools outside your core scope

Master's or engineering degree in microelectronics, materials science, physics, or related field — or equivalent experience

Fluent English; French not required (fab teams work in English)

Strongly valued for this scope — electron-beam lithography (tool operation, job preparation, exposure strategy, cassette and holder management); direct-write or laser lithography; resist processing; wet chemistry and lift-off, with the associated handling and wet bench safety practice.

Also valued — R&D or pilot-line environments where production and development share the same tools; superconducting materials, Josephson junction or quantum device fabrication; commissioning or qualifying tools in a new facility.

Working conditions

On site in Aubervilliers, in cleanroom garment daily. Standard working hours — no shift work and no night work.
