Yoh, A Day & Zimmermann Company

Southampton / Global

Senior System Test Engineer

Job Description

Most test engineering roles involve executing someone else's plan.

This one doesn't.

The challenge here is figuring out how complex wireless systems behave when the real world gets involved.

The work sits where RF, software, digital systems and 5G communications meet. One day you could be investigating a PHY layer issue, the next building Python automation, debugging a system-level problem or helping translate customer requirements into a test strategy.

This isn't a role for someone who wants to follow a script.

It's for an engineer who enjoys understanding how things work.

What makes it interesting?

Advanced 5G and NTN technology
Difficult technical problems that don't always have obvious answers
Exposure across RF, software, systems and validation
Customer-facing projects with real-world impact
A small engineering team where people are trusted to make things happen

You'll probably have experience in some combination of:

Wireless communications
RF engineering or RF test
Python development and automation
System integration and validation
4G/5G, PHY or MAC layer technologies
Troubleshooting complex technical issues

Most importantly, you'll be the type of engineer who enjoys solving problems, learning new things and taking ownership.

If you've spent your career close to wireless systems and still enjoy getting hands-on with technology, we'd like to hear from you.
