Forming part of our Electronic Warfare Support Group (EWOS), our Countermeasure Development team provide technical advice and support to our customers relating to countermeasure development, engineering support and delivery, as well as supporting internal initiatives relating to innovation and research, projects, training and bid delivery.
You will have an opportunity to develop our in-house countermeasure simulation software tool, CounterWorX®, modelling physical interactions and phenomena across dynamic simulations. This opportunity will also expose you to working with our software development team, and the assurance process all releasable software products must follow.
The team are based across two MASS sites (head office, Enterprise House, in Little Paxton, and our modern Lincoln offices on Teal Park). When project classifications allow, they tend to work three days in the office and two days from home, giving you the best of both worlds: flexibility and collaboration.
How you’ll support us
As a modeller within the team, you will have the autonomy to develop models, add new features into the countermeasure software, and solving customer challenges and requirements. This is a rapidly growing team, allowing for career development opportunities within the team and across the broader EWOS group.
The invaluable experience you’ll bring, to help us achieve more
Core to this role will be your understanding of Physics/Mathematical principles at degree-level, as well as experience with either Electro-Optics (EO), Infra-Red (IR), or Radio Frequency (RF) sensors, within a defence setting.
The role will allow you to analyse, design, model (MATLAB/Python/Simulink), and verify countermeasure techniques across a variety of real-world scenarios, culminating in delivery to customers for use in operation. Your experience developing either deterministic, stochastic, or exploratory models will help optimise countermeasure parameters for best performance against specific threats.
Essential experience
- Degree in a STEM subject ideally in Mathematics, physics or electronics
- Experience using programming software (MATLAB/Simulink/Python etc.)
- Experience in at least one stage of model development (Design, Build, Integration, Test, Deployment etc.)
- Understanding of modelling techniques (stochastic, deterministic, exploratory etc.)
Desirable experience
- Understanding of either mathematics or physics involved in Radar, Electro-Optics or Infra-Red system operation
- Mentoring of junior team members
- Interest in new technologies and their application within an EW domain
- Deployment of models to batch running hardware
Our non-negotiables:
Due to the highly secure nature of the projects that you will be involved with, you must be:
- A UK National and eligible to work in the UK
- Eligible to obtain and maintain a UK Government Security Check (SC) clearance.
