Overview
Role: Senior Software and Integration Engineer – 5G PHY/MAC and High-Performance Baseband Systems
Company: Noema Solutions Ltd.
Location: UK-based, we are unable to provide sponsorship for this role.
Who We Are
Noema Signal Labs Ltd is an early-stage venture backed by Cambridge Future Tech, commercialising a breakthrough signal processing framework that dramatically increases spectral efficiency across wireless communications networks. The core technology can be integrated into existing network layers to enable significantly more data transmission over any given spectrum. Target applications span 5G, non-terrestrial networks (NTN), satellite communications, and defence-grade wireless infrastructure.
The Opportunity
We are looking for a Senior Software and Integration Engineer to help us bring this technology into commercial-grade 5G RAN systems. You will work at the heart of turning a breakthrough algorithm into real-world, deployable infrastructure, integrating advanced MIMO signal processing into live RAN platforms and helping define the engineering foundations the company will build on as it scales toward 6G, NTN and defence-grade deployments.
