What will you be doing?

Defining digital subsystem architectures across satellite payload and ground communication systems
Translating high-level product and system requirements into scalable digital processing capabilities
Collaborating across payload, network, air interface, and security domains to deliver cohesive digital designs
Supporting future waveform and communication standard evolution including DVB-S2X and 3GPP NTN
Assessing emerging FPGA, ASIC, SoC, and chiplet technologies for suitability within space-grade environments
Leading Digital-in-the-Loop (DIL) modelling and prototyping activities to validate performance, latency, and power targets
Deriving compute resource requirements including throughput, memory bandwidth, LUT utilisation, and DSP allocation
Defining and governing high-speed digital interfaces including JESD204, SpaceWire, and high-speed Ethernet
Supporting the integration of secure hardware capabilities including encryption, secure boot, and resilience mechanisms
Translating architectural concepts into actionable specifications and interface control documentation for implementation teams
Providing technical oversight across firmware and hardware development activities to ensure alignment with system intent

What You’ll bring

Strong understanding of digital system architecture and high-performance processing within communication systems
Capability to define and integrate complex digital subsystems across space and ground environments
Knowledge of FPGA, ASIC, SoC, and emerging silicon technologies used within advanced processing systems

Ability to translate system requirements into compute resource and hardware utilisation needs
Knowledge of high-speed digital interfaces including JESD204, SpaceWire, and Ethernet
Understanding of signal integrity, synchronisation, and high-speed data transfer considerations
Awareness of how digital processing impacts RF system performance including beamforming and pre-distortion techniques
Proficiency in modelling and simulation using MATLAB, Simulink, or Python for system-level validation
Understanding of hardware resilience and secure design principles within high-reliability or space-grade environments
A systems-thinking mindset with a structured and analytical approach to performance, scalability, and technical trade-offs
