Senior Spectrum Systems Engineer

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.

What will you be doing?

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

What You’ll bring

Strong systems engineering fundamentals (requirements, V&V), ideally in an MBSE environment

Deep understanding of RF spectrum compliance (EPFD, PFD, EIRP, emissions)

with tools like Visualyse EPFD, STK, or similar

Strong Python or MATLAB skills for simulation and analysis

Solid understanding of LEO systems, link budgets, and orbital dynamics

Knowledge of ITU-R regulations and NGSO systems

Familiarity with DVB-S2X, 3GPP NTN, or similar standards
