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 working hours.
- Following safety protocols and ensuring compliance with laboratory regulations.

?Minimum requirements:

- Studies in industrial, mechanical or electrical engineering, or a related technical field.
- Ability to create clean, structured and concise documentation and resources that improve the day-to-day operation of the lab.
- Motivation to learn how a quantum computer is built and operated, and to grow with the lab.
- Previous experience in a laboratory, workshop or technical maintenance environment.
- Good understanding of mechanics and electronics.
- Methodical and organised, with the discipline to keep records accurate over time.
- Strong problem-solving skills and the ability to manage multiple tasks efficiently.
- A good sense of aesthetics and order, and care for keeping the lab clean, well organised and professional.
- Good communication skills and a teamwork mindset.
- High level of Spanish and English (C1 or higher), both spoken and written.

?Preferred Skills:

- Measurement hardware (oscilloscope, multimeter, VNA).
- Cryogenics or cryostat operation.
- Quantum technologies or quantum computing hardware.
- AI tools applied to documentation and engineering work.
- Mechanical design and CAD tools.

?Working conditions:

- Full-time contract.
- On-site work,



Monday to Friday.
- Participation in the lab on-call rotation, shared with the rest of the lab team.
- Location: Offices and Lab in Carrer Veneçuela, 74, 08019, Barcelona, Spain.
