Principal RF Payload Lead Engineer – Phased Arrays / Direct-to-Device / NTN
We are currently partnered with a space communications organisation developing direct-to-device connectivity. This role owns the end-to-end technical solution for RF communications payloads, spanning requirements, system architecture, hardware development, integration, testing, on-orbit performance, and mission operations support. As the first hire into a new group, you will also help establish how the technical work is delivered.
Key responsibilities- Own the RF payload architecture for direct-to-device connectivity.
- Develop RF architectures incorporating phased-array antennas, RF front ends, frequency planning, and waveform selection aligned with cellular standards.
- Lead phased-array design and analysis, including beamforming strategy, scan performance, EIRP, G/T, coverage optimisation, and handover.
- Own end-to-end link design, including link budgets, modulation and coding, Doppler, interference analysis, and regulatory considerations.
- Lead integration and testing activities, including functional testing, RF performance verification, over-the-air testing, and environmental qualification.
- Work across cellular teams to ensure compatibility with 3
GPP and NTN behaviour over satellite links. - Collaborate with RAN and core network groups.
- Experience designing RF systems and taking them through build, test, and deployment.
- Experience with RF communications payload architecture.
- Experience with phased-array antennas and phased-array design.
- Experience with waveform selection aligned to cellular standards.
- Strong understanding of beamforming, scan performance, EIRP, G/T, coverage optimisation, and handover.
- Experience with end-to-end link design, including link budgets, modulation and coding, Doppler, and interference analysis.
- Experience with RF integration and test, including RF performance verification and over-the-air testing.
