Test Technician

The role

You will work hands-on with Proxima-designed components, magnets, mechanical assemblies, and critical systems. You will support their build, assembly, integration, and testing to turn ambitious designs into reliable hardware.

What you will do

• Run acceptance and characterization tests across HTS tape, cables, assemblies, and coils.
• Prepare and identify test articles by cutting, soldering, terminating, mounting, and fixturing.
• Install sensors, voltage taps, feedthroughs, and measurement wiring.
• Set up and operate dimensional inspection equipment, electrical instruments, high-current supplies, liquid-nitrogen baths, cryostats, cryocooler-based rigs, and vacuum systems.
• Carry out critical-current, n-value, joint-resistance, insulation-resistance, and high-voltage insulation tests.
• Configure data acquisition and check connections, signal quality, and instrument settings.
• Maintain full traceability of sample identity, test configuration, instrument settings, raw data, observations, and deviations.
• Check data for completeness and plausibility and compare results with acceptance criteria.
• Troubleshoot test setups, wiring, instrumentation, and data acquisition.
• Keep rigs ready for testing through pre-use checks, calibration, and consumables management.

Required qualifications

• Technical apprenticeship or qualification in electronics, mechatronics, laboratory work or a related discipline, or equivalent practical experience.
• Hands-on testing, laboratory or measurement experience in an industrial, research or engineering environment.
• Practical electrical measurement skills.
• Ability to read engineering drawings and wiring diagrams.
• Ability to work precisely to a formal test procedure.
• Experience using data-acquisition systems and basic data reduction.
• Disciplined approach to safety, configuration control and traceability.
• Ability to work across teams and communicate observations clearly.
• Working English for following procedures, recording results and discussing technical findings.
• Ln2 Experience

Nice to have

• Experience with superconductoring, high or low temperature, cables or magnets, including critical-current measurements.
• High-current DC testing or quench detection.
• Experience with cryogenic testing, liquid nitrogen or helium, cryocoolers or vacuum systems.
• Specialist low-level instrumentation experience, including voltage taps, feedthroughs, sensor mounting, grounding and shielding.
• CAD literacy for reviewing or developing test fixtures.
• Python or LabVIEW for test automation, data handling, and plotting.
• German language skills.

Before you apply

• Recruiter Interview (30-60 min)
• Technical Screening (30 min)
• Technical Panel (3x60 min)
