- Execute: Own the Design of Experiments (DoE) within world-class clean-room facilities.
- Scale: Transform prototype fabrication runs into stabilized, high-maturity manufacturing processes.
- Analyze: Use statistical data and physical model fitting to correlate optical and electrical device properties.
Requirements
What You Know
You are a specialist who thrives in the microscopic world, blending a deep understanding of physics with the precision of semiconductor manufacturing.
- Education: A technical degree (MSc or PhD) in Electrical, Chemical, Physical, or Nano Engineering.
- Clean Room Mastery: Several years of hands-on experience with Lithography, Dry Etching, PVD, or CVD.
- Bonding Expertise: Strong, proven experience in wafer or die bonding technologies, this is critical for our active integration goals.
- Data Driven: In-depth knowledge of manufacturing processes with the ability to define and execute complex DoEs and statistical data analysis.
- Maturity Mindset: Experience in increasing process maturity (moving from R&D to Pilot Line/Production) is a significant advantage.
Who You Are
Technology moves fast, but you move faster. We are looking for a teammate who brings more than just a certificate to the table.
- A Process Enthusiast: You don't just work in a clean room; you have a genuine passion for the processing environment and the "magic" of fabrication.
- A Critical Thinker: You are open-minded but analytical, always questioning "how can we make this more stable?"
- Solution-Oriented: When a fabrication run hits a snag, you focus on the fix, not the fault.
- A Global Communicator: You enjoy a collaborative, international environment and possess working proficiency in English (French is a plus).
- Independent yet Integrated: You can drive your own projects while seamlessly contributing to a multidisciplinary R&D and Process team.

TECHNICAL & MARKET ANALYSIS | Appended by Quantum.Jobs
This strategic role is fundamental to transitioning ultra-low loss Photonic Integrated Circuit (PIC) technology from a laboratory-validated state to a robust, commercially scalable foundry offering. The core mandate is to de-risk and stabilize complex heterogeneous integration processes, specifically the merging of active electro-optic materials like thin-film Lithium Niobate onto a high-performance Silicon Nitride (SiN) platform. By formalizing this process technology, the engineer directly addresses critical hardware bottlenecks in the quantum, LiDAR, and high-bandwidth space communications markets, establishing the manufacturing maturity (MRL) necessary for next-generation sensor and computation systems.
INDUSTRY & ECOSYSTEM ANALYSIS
The quantum and advanced sensor markets are currently constrained by a manufacturing maturity gap, where system-level performance gains are increasingly limited by the reliability and scalability of component fabrication, rather than material science breakthroughs alone. Photonic Integrated Circuits (PICs) form a foundational layer of the hardware value chain, serving as the critical interface between core physical phenomena and application-specific modulation/sensing. Ligentec's strategic focus on the ultra-low loss SiN platform caters to applications demanding high signal fidelity and long coherence times, such as quantum entanglement distribution and advanced coherent detection. The integration of high-performing active materials—the central challenge of this role—is essential for pivoting from passive PIC architectures to hybrid-active systems without compromising yield or optical performance stability. The current vendor landscape exhibits a severe deficiency in high-volume, multi-material foundries capable of supporting semiconductor-grade reliability for such hybrid PICs, thereby elevating the technical readiness level required for commercial deployment. Process Engineers skilled in converting highly specialized R&D fabrication runs into statistically controlled, pilot-line production workflows are exceptionally rare, representing a critical workforce constraint across the deep-tech sector. This position is a direct intervention against this systemic bottleneck, tasked with stabilizing proprietary, advanced heterogeneous integration techniques into certified manufacturing protocols to accelerate the commercialization timeline of quantum and advanced photonics components.
TECHNICAL SKILL ARCHITECTURE
The required expertise centers on establishing robust process control windows to ensure feature predictability and high-throughput reproducibility. Core competency areas include precise control over sub-wavelength pattern transfer via advanced lithography, optimization of high-aspect-ratio features through dry etching kinetics, and stable material deposition via PVD/CVD. Crucially, successful execution hinges upon deep proficiency in wafer-level or die-to-wafer bonding—a prerequisite for robust heterogeneous integration that guarantees thermal stability and minimizes interface scattering losses in the coupled SiN/LiNbO3 stack. These skills collectively enable precise geometric and material control over microscopic features, directly translating into predictable macro-level device metrics like insertion loss and electro-optic modulation efficiency. Mastery of Design of Experiments (DoE) and Statistical Process Control (SPC) is non-negotiable; this data-driven methodology is the mechanism for establishing quantitative correlation models between micro-fabrication parameters and device performance, which is foundational for maximizing throughput and minimizing variability across production cycles. * Establishes the foundation for commercial-scale Quantum Random Number Generation (QRNG) hardware.
