Career development support
Come and join our expanding Electronic Warfare Operations Support Group (EWOS) which is made up of 60+ electronic warfare specialists. From all manner of backgrounds, our engineers, scientists, and ex-military personnel combine their experience to help our customers achieve the true operational potential and help keep their people and platforms safe.
We are continuing to grow our team at Porton Down, Salisbury, working on key state-of-the-art research, development, and delivery projects, led by our technical customer.
About the Role
The primary role is to support testing and optimisation of RF receiver hardware in a new synthetic range (laboratory), with additional support to over-the-air testing (anechoic chamber) and field trials. This will require using a range of RF test equipment to perform digital and analogue injection testing within synthetic EW scenarios.
This role will allow autonomy to explore ways to optimise RF receiver performance through configurable memory (mission data) to improve real-world operation of the system when deployed to target platforms. This exploratory process will focus on the increasingly congested and contested electromagnetic environment, developing tactics, techniques, and procedures (TTP) for the RF receiver.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.

To accurately represent the synthetic use cases these systems are required to integrate into, the role will liaise with military, academia, industry and international stakeholders, to complete the validation process.
This new lab will be using the latest commercial-off-the-shelf (COTS) development Radio Frequency System on Chip (RFSoC) boards to achieve a high-fidelity electromagnetic environment. You will become an expert in configuring and calibrating these devices to aid testing of the RF receiver systems.
This role also has influence over future development work, driving requirements through analysis of current EW systems. As such, an understanding of requirements generation and the engineering lifecycle will be valuable to the role.
Working autonomously with unprecedented access to the customer, you will be crucial to ensure the success of these key projects, all whilst being supported by our on-site and home-site MASS teams.
The invaluable experience you’ll bring, to help us achieve more.
