About the role as R&D Test Engineer
This role offers a blend of practical and theoretical R&D work. You’ll spend time both in the laboratory and analyzing results, helping to bridge the gap between hardware, electronics theory, and real-world applications.
You don’t need to be a seasoned engineer to succeed; what matters most is your interest in electronics, curiosity about how things work, and motivation to work hands-on with real products. Whether you have a Bachelor’s degree or have gained your competence through practical experience, we’re interested in hearing from you.
You will be involved throughout the R&D process: setting up test environments, performing measurements, analyzing results, troubleshooting, and supporting development through practical electronics work.
At Comsys, you’ll have the opportunity to learn and grow, working alongside experienced colleagues in a collaborative environment.
Your responsibilities

Set up and configure laboratory test units and test environments for ADF filters


Perform measurements and execute tests according to test plans and specifications


Analyze test results and support development with insights from data


Ensure test equipment and lab setups are fully operational and correctly configured


Document results and produce structured test reports and protocols


Assemble, modify, and repair test units and prototypes as needed


Troubleshoot issues in test setups, prototypes, and laboratory equipment


Who we’re looking for
We welcome candidates with different paths into electronics, including:

A Bachelor’s degree in electronics, mechatronics, or related fields who want to work closer to hardware


A practical, hands-on background in electronics, gained through work experience or technical vocational training where you’ve developed a strong interest and solid skills in laboratory work, testing, production, or similar environments.


You also bring:

Experience with laboratory testing and measurement of electronic products


Familiarity with test equipment and ideally power electronics


Practical skills with soldering and electronics assembly


Understanding of PCBAs, circuits, and electronics theory


Strong communication skills in English and Swedish (both required)


Your profile
You are a curious, analytical, and structured person who enjoys working in a laboratory and learning from real-world electronics. You are comfortable bridging theory and practice, collaborating with others, and taking initiative to solve technical challenges.
You thrive in a learning-oriented environment, are proactive, and are motivated to further develop your skills.
What it’s like to work at Comsys

A friendly, knowledgeable, and supportive team


A culture that encourages curiosity, learning, and hands-on experience
