Senior Countermeasure Development Engineer St Neots (PE19)

• 25 days annual leave, inclusive of up to 3 days December shut-down
• Buy or sell up to 5 days annual leave
• Two pension schemes to choose from
• Private medical & dental Insurance + discounts for additional family members
• Life Assurance scheme up to 4 x salary
• Multiple save schemes
• Electric/hybrid car leasing scheme
• Cycle to work scheme

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 youll support us

As a senior 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. You will be responsible for managing technical work for junior team members, as well as line management of some of the junior engineers.

This is a rapidly growing team, allowing for career development opportunities within the team and across the broader EWOS group.

The invaluable experience youll bring, to help us achieve more

Core to this role will be your detailed understanding of Physics/Mathematical principles at degree-level, as well as experience with at least one of Electro-Optics (EO), Infra-Red (IR), or Radio Frequency (RF) sensors and systems, 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. Additionally, your ability to capture modelling requirements and ensure delivery against these will be crucial.

• Experience using programming software (MATLAB/Simulink/Python etc.).
• Allocation of work packages/tasks to junior team members.
• Experience in at least two stages of model development (Design, Build, Integration, Test, Deployment etc.).
• Understanding of modelling techniques (stochastic, deterministic, exploratory etc.).
• Generation of simulation requirements, configuration and analysis reports.
• Experience modelling/programming RF/EOIR countermeasure techniques (platform protection).
• Experience line managing a team.
• Knowledge of either mathematics or physics involved in Radar, Electro-Optics or Infra-Red system operation.
• Interest in new technologies and their application within an EW domain.
• Mentoring and coaching junior team members.

Due to the highly secure nature of the projects that you will be involved with, youmustbe:

• A UK National and eligible to work in the UK
• Eligible to obtain and maintain a UK GovernmentSecurity Check (SC) clearance.
