About Qilimanjaro
Qilimanjaro is building full-stack superconducting quantum computing systems, combining QPUs, cryogenic infrastructure, control electronics, racks, cabling, instrumentation, software and deployment infrastructure. Our Systems & Engineering division turns quantum processors into complete, reliable and scalable quantum computers.
We are looking for a senior technical owner for the cryogenic, thermal and mechanical foundation of our quantum systems. This is not a junior mechanical drafting role or a general lab-support role. It is a high-impact systems-engineering position for someone who can define cryomechanical architectures, create thermal and mechanical design rules, debug complex physical systems, and make future setups reproducible, maintainable and scalable.

Role Mission
Own the cryogenic, thermal and mechanical architecture of Qilimanjaro quantum setups, ensuring that systems can be designed, installed, cooled down, diagnosed, maintained and scaled with engineering discipline.

Why this role matters
As Qilimanjaro systems scale,



the physical infrastructure around the QPU becomes one of the main determinants of system reliability and repeatability. Thermal budgets, cryogenic wiring, mechanical routing, site readiness, cooldown behavior, thermalization, shielding and maintenance procedures all affect whether a setup can move from a one-off laboratory system to a repeatable quantum-computing platform.

This person will become the senior reference for questions such as:
- Can this setup be built, cooled down and maintained safely?
- Is the thermal budget compatible with the QPU and wiring architecture?
- Are the mechanical constraints understood before procurement and installation?
- Are site-readiness requirements explicit enough for internal and client deployments?
- Can we diagnose whether a problem comes from cryogenics, mechanical integration, routing, thermalization, packaging, electronics or the QPU?
- Can junior engineers execute common
