Job Title: Principal Systems Mathematical Modeller

Location: Broad Oak – Portsmouth, Great Baddow – Chelmsford or Cowes – Isle of Wight. We offer flexible working arrangements – please speak to your recruiter about the options for this particular role.

Salary: Up to £75,900 dependent on experience. Part time & accruing hours available’ Please let us know if you would like to discuss these options.

You will be responsible for leading and undertaking mathematical analysis, modelling and simulation of new complex Radar systems targeting the strategic Future Air Dominance domain.

Identify, develop and evolve system capability solutions and resolve engineering issues for a range of operational scenarios through algorithmic definition and system performance modelling and simulation. Utilise modelling and simulation to verify and validate these solutions for customer stakeholders.

You will drive, with active contribution, the development of solutions from simulation through to through to design implementation and operational deployment.

You will be required to apply the principles of Systems Engineering to support various phases of the engineering development lifecycle and subsequently into system customer support which can encompass further system capability evolution.

What you’ll be doing:

Lead mathematical modelling and simulation development devising and evolving algorithmic and design solutions to meet system capability and performance requirements of new complex radar systems

Direct and undertake mathematical modelling and simulation to identify and develop cutting edge performance capability and novel solutions for future radar product technologies

Direct and undertake development novel solutions to evolving technical challenges and emerging issues that our customer community are facing

Support multi-disciplined engineering teams in the realisation, implementation, verification and validation of algorithmic and design solutions for deployable radar systems

Drive, conduct and underwrite system performance analysis and design trade-offs of principle system parameters in order to characterise and define system design constraints and limitations in various operational scenarios

Direct and undertake system performance analysis of integration and post trials data to inform radar system design solutions, and to generate customer acceptance evidence

Be a technical focus point for development and analysis activities, preparing and presenting technical aspects to internal and external stakeholders

Apply and champion a breadth of knowledge, skills and experience of Systems Engineering (e.g. ISO 15288) to design and develop solutions and resolve engineering issues and problems for a range of products and engineering situations that can realise Future Air Dominance

Your skills and experiences

A strong mathematical and engineering mind-set with an innovative approach to problem solving that can be applied to resolving complex technical and system level requirements

A comprehensive understanding of signal processing, tracking or classification algorithms and techniques employed on contemporary radio, satellite, radar or sonar real-world systems

A good understanding of factors that can affect the real-world performance of radar systems and how these can impact modelled or simulated performance prediction

Extensive experience of mathematical simulation tools/languages (e.g. Mathworks MATLAB, Simulink, Pearl, Python, MathCAD)

Higher education (or equivalent experience) in a relevant STEM discipline

You’ll receive benefits including a competitive pension scheme, enhanced annual leave allowance and a Company contributed Share Incentive Plan. You’ll also have access to additional benefits such as flexible working, an employee assistance programme, Cycle2work and employee discounts – you may also be eligible for an annual incentive.

The Radar Systems Modelling & Simulation team:

You will be working as a Principal Systems Mathematical & Simulation Modeller within a radar product team of inter disciplinary engineers from a bespoke portfolio of new and existing products as part of our prestigious Products delivery stream. This position provides excellent opportunities to develop both your own skills and also further your career within BAE Systems.

Our workplace in Cowes is an easily accessible commute from Southampton with a regular foot passenger ferry and BAE shuttle service from the ferry terminal to site.
