Join Us at the Forefront of Quantum Computing Innovation 🚀
As our manufacturing moves from R&D and low-volume production toward structured, scalable industrial output, we're looking for a hands-on Lean engineer who combines strong analytical skills with a pragmatic shop-floor mindset. You'll adapt Lean intelligently to a complex high-tech environment (long cycle times, expensive equipment, cleanroom and yield constraints) and help us manufacture faster, more reliably and at greater scale, without compromising quality or innovation.
Your Key Resonsabilities
Define and deploy Lean principles across our semiconductor, photonic and system manufacturing, adapting them intelligently to a complex, low-volume/high-mix environment
Map end-to-end flows with Value Stream Mapping, define current and future states, and build improvement roadmaps based on real constraints
Analyze cycle time at product, workshop and process-step level, separating processing, queue, waiting, transport and test times, and lead actions to reduce lead time and WIP
Introduce pull-flow or controlled-WIP principles where relevant and improve flow between workshops and production stages
Identify bottlenecks, analyze equipment loading and capacity losses, and optimize sequencing around constrained equipment
Implement and improve OEE monitoring on critical equipment, analyze availability, performance and quality losses, and support preventive maintenance and TPM initiatives
Develop standardized work with Methods and Production to reduce variability between operators and runs
Build shop-floor and visual management systems (safety, quality, delivery, cost, WIP) with daily routines and escalation mechanisms
Lead structured problem solving (PDCA, DMAIC, 5 Why, Ishikawa, Pareto, Kaizen) and build these capabilities within production teams
Deploy and sustain 5S, including in cleanroom environments, while respecting contamination-control and safety requirements
Work with Process Engineering and Quality to reduce scrap, rework and yield losses without compromising process robustness
Identify cost-reduction opportunities, build business cases for Lean projects and track actual savings
Embed Lean into new production lines, layouts and equipment investments, so scale-up doesn't replicate today's inefficiencies at a larger scale
Requirements
Engineering degree or Master's in Industrial, Manufacturing or Operations Engineering, or a related technical field
Minimum 5 years of experience in Lean Manufacturing, Operational Excellence, Manufacturing Engineering or Continuous Improvement
Proven track record of improving manufacturing performance
Hands-on expertise in VSM, Standardized Work, 5S, OEE, and cycle-time and WIP reduction
Strong data-driven, analytical mindset
Ability to lead cross-functional initiatives and drive change
Fluent French and professional English
Nice to have
Experience in semiconductors, photonics, cleanroom or wafer fab, industrial scale-up, SPC, or ERP/MES environments; Lean Six Sigma Green or Black Belt certification
Benefits
Competitive salary, flexible based on your experience
Profit-sharing & company savings plan
100% health coverage (Alan)
50% transport reimbursement or sustainable mobility bonus
Meal vouchers (Swile), Gymlib fitness support
Childcare assistance & referral bonuses (€1,000–€2,000)
What we offer:
A meaningful role with real ownership, from day one
A team eager to collaborate and grow with you
A hybrid work model (3 days/week onsite in Massy, 1 day in Paris, 1 to 2 days remotely)
Daily exposure to the entire quantum stack — from high-level APIs to low-level firmware, and everything in between.
