Principal System Test Engineer 5G | RF | Python | Wireless Communications
Southampton | Hybrid Working
Circa £80,000 Basic + Annual Bonus + Equity + Private Medical + Excellent Benefits
Help define how the next generation of wireless communications technology is tested.
Most test engineering roles are about validating existing products.
This opportunity is different.
AccelerComm develops high-performance Physical Layer technology that powers some of the world's most advanced 5G and satellite communication systems. As the business continues to grow, they're looking for a Principal System Test Engineer to take ownership of how complex wireless products are verified, automated and validated.
Working alongside highly experienced Algorithm, Software, FPGA and Systems Engineers, you'll design and develop scalable automated test capability, build Python-based test frameworks, integrate RF instrumentation and help shape the future of the company's verification strategy.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.

- Designing and developing automated Python-based test systems.
- Developing scalable verification frameworks for advanced wireless communications products.
- Integrating and automating RF test equipment including spectrum analysers, signal generators and VNAs.
- Defining test strategies from system requirements and 3GPP specifications.
- Working closely with Software, FPGA, Systems and Algorithm Engineers to solve complex technical challenges.
- Supporting customer demonstrations and occasional international customer engagements.

Your very own career expert that helps elevate your application to the next level.
We're interested in engineers with experience in:
- RF or Wireless System Test
- Python test automation
- 4G/5G, LTE or digital communications
- RF measurement equipment
- System integration and verification
- Embedded systems or wireless communications
Experience with 3GPP, lab automation, CI/CD, Hardware-in-the-Loop, ORAN or satellite communications would be beneficial but is not essential.
If you enjoy solving technically challenging problems, designing automated test solutions and working with engineers at the forefront of wireless communications, we'd love to hear from you.
