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

What you'll actually build

You will own end-to-end integration projects. Think: taking an optical source, a set of fiber-optic components, control electronics elements and turning them into a fully packaged, field-ready instrument, with mechanical housing, optics, electronics, and firmware-facing hardware all working together

You'll be a good fit if you've

- Integrated or packaged fiber-optic components and lasers into finished products. Fiber splicing/termination, alignment, coupling, and connectorization are second nature to you
- Designed mechanical enclosures and optical mounts in CAD (SolidWorks, Onshape, or similar) from concept to manufacturable parts
- Designed and laid out PCBs (ECAD) and understand how electronics, firmware,



and optics interact inside a real instrument
- Worked with lasers, optical test equipment, and standard electrical test gear (oscilloscopes, etc.) comfortable troubleshooting across disciplines
- Mentored or directed other technical staff. You'll be guiding a small team of CAD/mechanical technicians, reviewing their mechanical designs and folding in the optical/electrical requirements they have not accounted for
- Background at a Quebec photonics company
- CNC machining knowledge, 3D printing for prototyping, integrated optics packaging
- Experience with quantum, atomic, or precision optical reference systems

Why Ki3

We're a small, fast-moving team working at the edge of quantum photonics, real hardware, real deployments (research labs, telecom, defense), and your work will be the difference between a good idea and something that ships. You'll have real ownership over how our instruments are built.

Must be able to legally work in Canada and relocate to the Montreal area full time
