Work at the cutting edge of space technology with customers around the globe.
A mission-driven company making space accessible to help solve real-world challenges.
A diverse, ambitious, and supportive team.
Aim high, go beyond!
At Open Cosmos we are solving the world's biggest challenges from space, providing businesses, governments and researchers access to more readily available information than ever before - ready for the challenge? Then read on...
The Satcom team is responsible for the design, delivery and performance of Open Cosmos' satellite communications services, spanning the space segment, ground infrastructure and global connectivity.
We're now looking for a Senior Spectrum Systems Engineer to take ownership of how spectrum compliance is designed into our satellite systems from day one.
As Senior Spectrum Systems Engineer you'll take the lead on translating spectrum regulations into system design-using modelling and simulation to ensure compliance without compromising performance.
You will:
Translate regulatory constraints (EPFD, PFD, EIRP) into system and sub-system requirements
Build and own end-to-end simulation models for interference and spectrum compliance
Define system design limits ("design-to-compliance") for payload and user terminals
Model interference, coexistence, and mitigation strategies across constellations
Produce high-quality datasets to support ITU filings and coordination
Lead verification and validation of spectrum compliance (ground and in-orbit)
Shape spectrum usage strategies (frequency reuse, beam hopping, power control)
Support external regulatory engagement (ITU-R, WRC) with simulation-backed insight
