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 integral connectivity.

We now require a Senior Antenna and RF Payload Engineer to join the team.

What will you be doing?

As a Senior Antenna and RF Payload Engineer, you’ll lead the modelling, specification, and validation of antenna and RF payload systems across both satellite payloads and user terminals.

You’ll play a key role in translating high-level mission and service requirements into robust, high-performance hardware designs ready for deployment in demanding operational environments.
- Lead antenna and RF payload design activities across phased arrays, reflectors, and beamforming systems




- Define and validate electromagnetic simulations to optimise antenna and RF performance
- Support beam steering, coverage optimisation, and spectral compliance across satellite constellations
- Define technical specifications and interface requirements for RF modules and payload subsystems
- Govern frequency planning, signal integrity, and linearity requirements across RF chains
- Perform cascade analysis to optimise gain, noise figure, and overall link performance
- Support radiometric modelling and PFD analysis to ensure regulatory compliance
- Lead prototyping and hardware validation activities including OTA testing and engineering model development
- Define and oversee qualification activities including vibration, TVAC, and radiation testing
- Work closely with system architects, RF engineers, hardware teams, and spectrum specialists to deliver integrated solutions

What You’ll bring
- Strong understanding of antenna theory and RF system design includ
