Qilimanjaro Quantum Tech is a quantum computing company based in Barcelona that designs, builds and operates superconducting quantum computers. The company is looking for a Junior Lab Engineer to join the lab team: a role that combines ownership of the lab's documentation, protocols and inventory with hands-on work in the operation, maintenance and upgrade of the quantum setups. ?

Key Responsibilities
An important part of the role is documentation and inventory, and another important part is hands-on work on the quantum setups and the lab infrastructure. The position is designed to grow with the person: the engineer will learn how a quantum computer is built, cooled down and operated while building the documentation that keeps the lab running. Documentation, protocols and inventory:
• Writing, standardising and maintaining protocols for lab operations, quantum setups and maintenance routines.
• Owning the inventory of lab equipment, tools, components and consumables, including location, quantity and status.
• Registering new equipment on arrival: serial numbers, manuals, calibration data and location.
• Tracking stock levels of consumables and flagging reorders before they run out.
• Documenting new installations, upgrades and modifications to the quantum setups as they happen.
• Keeping protocols up to date as the lab evolves, and making sure the team works from the current version.
• Keeping maintenance logs, service records and equipment status up to date.
• Contacting suppliers for quotes, order follow-up and technical documentation. Quantum setups, maintenance and operations:
• Operating the cryostats of the quantum setups: cool-downs, warm-ups and routine monitoring.
• Supporting the installation, integration and commissioning of new quantum setups, laboratory equipment and infrastructure upgrades.
• Assembling and installing mechanical parts, shielding, HPC racks and cabling according to specifications.
• Performing preventive and corrective mechanical and electrical maintenance on lab equipment and infrastructure.
• Wire bonding and exchange of quantum chips in the cryostats,



together with the lab team.
• Assisting in setting up and modifying experimental setups and laboratory configurations.
• Workshop and electronics tasks: using hand and power tools, cable preparation, soldering and PCB preparation.
• Troubleshooting and resolving technical issues related to the operation of the lab.
• Taking part in the on-call rotation of the lab team, which keeps the quantum computers running outside
