Help Shape the Future of Wireless Communications
At NEC Telecom MODUS Limited (NECTML), we're the UK research and development centre behind many of NEC's next-generation mobile network technologies.
As part of NEC's global Network Solutions Business, our Radio Systems Division develops the advanced algorithms, software and hardware architectures that power 5G Advanced, Open RAN and the evolution towards 6G. Our engineers don't just build technology—they help define the international standards that shape the future of wireless communications through active participation in 3GPP RAN1 and RAN2.
We're looking for an experienced Signal Processing Architect to join our highly respected engineering team and play a leading role in designing the Layer 1 and Layer 2 signal processing technologies that underpin NEC's future radio products.
If you're passionate about digital signal processing, wireless communications and solving complex engineering challenges at the forefront of the industry, this is an opportunity to make a genuine global impact.
About NECTML
NECTML is NEC's specialist UK research and development centre for mobile communications.
Working closely with NEC engineering teams in Japan and across the globe, we develop the technologies behind NEC's next-generation mobile infrastructure. Our work spans:
- Advanced Layer 1 and Layer 2 architecture
- Link-Level and System-Level simulation
- Real-time software development
- FPGA and hardware IP development
- Applied wireless communications research
- 3GPP standardisation
Our engineers combine cutting-edge research with real product development—taking ideas from concept, through simulation and architecture, into technologies deployed in commercial mobile networks worldwide.
The Opportunity
As a Signal Processing Architect, you'll define and architect key Layer 1 and Layer 2 signal processing functionality across multiple development platforms, including:
- High-fidelity Link-Level Simulators
- System-Level Simulators
- Virtualised Distributed Unit (vDU) software
- Radio Unit (RU) hardware IP
Reasons to use Rodeo
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.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Working alongside world-class engineers, you'll help drive innovation across NEC's product portfolio while contributing to the future direction of global wireless standards.
