RF Quantum Hardware Engineer – Cryogenic Lab Specialist

Entangled Future; Espoo; Hybrid; EUR 50,000 - 90,000; Full time

Job summary

IQM Quantum Computers in Espoo, Finland, seeks a mid-level Quantum System Implementation Engineer to join the hardware engineering group on site. You will assemble and test cryogenic and room-temperature RF setups, measure performance, and work with scientists to resolve issues and document results for production.

You will collaborate with R&D, Production, and Delivery and Commissioning, own small tasks, write clear assembly instructions, and help improve measurement setups while maintaining lab

Qualifications

• BSc or MSc in Electrical Engineering, Electronics, RF Engineering, Physics, Quantum Technology or related field.
• At least 5 years of hands-on RF experience in a lab, research or industry setting.
• Strong RF fundamentals: S-parameters, transmission lines, attenuation and amplification.
• Practical experience with a VNA, spectrum analyser, signal generator and multimeter, including testing microwave components.
• Hands-on assembly skills. You build your own setups, solder, and do precise wiring work, also in tight spaces.
• Experience working in an electrostatic discharge (ESD) protected area and following structured lab practices.
• Strong documentation skills. You write instructions that someone else can follow and repeat.
• You think critically and try to solve problems yourself first, and you know when to raise a flag and ask for guidance.
• You learn fast, stay curious and take initiative, while following safety and process guidelines.

Responsibilities

• Assemble, install and verify cryogenic and room-temperature RF cabling, attenuators, amplifiers, filters and coaxial assemblies.
• Run RF measurements with VNAs, spectrum analysers and signal generators, then analyse the data and explain what it means for system performance.
• Troubleshoot signal integrity, impedance mismatches and noise in measurement setups.
• Support commissioning and performance testing of cryogenic systems used for RF and quantum device testing.
• Work with scientists and senior engineers to improve measurement setups and validate new assemblies.
• Own small engineering tasks and sub-projects, from planning and gathering information to execution and reporting.
• Write clear assembly instructions and documentation so production teams can repeat your work.
• Keep the lab safe and organised, and suggest practical improvements to designs and processes.
