About Us:

We are building the photonic PCB, the missing piece of technology that takes integrated photonics to scale. After a decade of research into using light to manipulate information at the micrometer scale, we found that optical integration was the main bottleneck for building high-performance optical chips. So we set out to solve it. Our 3D optical interconnect solutions connect individual photonic components into functional systems, and that work sits underneath the next wave of progress in AI, computing, sensing, and telecommunications. We think optical integration is one of the most important problems in photonics right now, and we are building the foundation that decades of future innovation can rest on.

Position Overview:

We are looking for a senior Process & Microfabrication Engineer to advance the development of our 3D photonic interconnect microfabrication processes. This is the work that turns individual components, lasers, silicon photonics chips, chiplets and fibres, into systems that actually function together. You will own the development of processes and original recipes to be deployed at scale, and you will help shape how we approach this problem as we grow. You would be one of our first 5 hires outside the founding team, so the decisions you make early will carry through everything we build next.

Key Responsibilities:

• Lead the development of standard nanofabrication process workflows for the realization of cutting-edge photonic products, using techniques including - but not limited to - 3D lithography, fiber array attachment, and component placement & encapsulation.
• Drive internal R&D and validation of new functionalities in close collaboration with an international customer base, delivering standard solutions to their needs.
• Produce clear technical documentation and reports on work performed, for both internal team, reviews and external customer presentations.
• Monitor and manage infrastructure needs, including consumables, inventory, and equipment maintenance.
• Participate in strategic planning and business development activities.

About you:

You are happiest when the problem is genuinely hard and the path is not yet clear. You like working things out for yourself, you enjoy being part of a small multidisciplinary team, and you want your work to matter. You will fit well here if you care about getting the fundamentals right and want a real say in how the technology takes shape.

Your core qualifications are:

• Bachelor’s, Master's degree or PhD in optics, photonics, physics, engineering, or a related field.
• Demonstrated experience leading fabrication process development for integrated optical components and photonic devices; expertise in 3D multi-photon lithography is a strong plus.
• 3+ years of industrial experience, ideally
• Very high attention to detail, with strong analytical and communication skills and a proven ability to work cross-functionally
• Full professional proficiency in English. French is optional.

Why join

• You would be joining at the point where the early decisions still shape everything, as one of the first hires alongside the founders. The mission is real and global, and the work sits at the foundation of where photonics is heading.
