Senior Optical Packaging and Instrumentation Engineer

Ki3 Photonics is a high-tech company dedicated to pushing the boundaries of quantum technologies. We design the hardware and software that form the backbone of quantum networks operating over standard telecom fiber. As a dynamic and rapidly growing company, we are looking for a skilled technician who can take a system combining optics, electronics, and mechanics from a blank CAD sheet to a finished, rack-mounted instrument. 

What you will actually build 

You will be responsible for end-to-end integration projects. Concretely: take an optical source, a set of fiber components, and control electronics, and transform them into a fully packaged, field-ready instrument where the mechanical housing, optics, electronics, and firmware-related hardware all work together. 

This position is for you if you have 

Integrated or packaged fiber components and lasers into finished products. Fiber splicing/termination, alignment, coupling, and connectorization hold no secrets for you 

Designed mechanical enclosures and optical mounts in CAD (SolidWorks, Onshape, or similar), from concept to manufacturable parts 

Designed and drawn printed circuit boards (ECAD) and understand how electronics, firmware, and optics interact in a real-world instrument 

Worked with lasers, optical test equipment, and standard electrical test equipment (oscilloscopes, etc.), comfortable troubleshooting across multiple disciplines 

Mentored or led other technical staff. You will guide a small team of CAD/mechanical technicians, reviewing their mechanical designs and integrating the optical/electrical requirements they might not have considered 

Additional assets 

Experience within a Quebec photonics company 

Knowledge of CNC machining, 3D printing for prototyping, packaging of integrated optics 

Experience with quantum or atomic systems, or precision optical references 

Why Ki3 

We are a small, agile team working at the cutting edge of quantum photonics, with real hardware and concrete deployments (research labs, telecommunications, defense). Your work will make all the difference between a good idea and a delivered product. You will have a real influence on how our instruments are built.
