Radar Modelling & Simulation Engineer

As Radar Modelling & Simulation Engineer, you will build and own the radar modelling capability that underpins a new radar product line. You will define, implement, and maintain a radar digital twin throughout the development lifecycle—using modelling and simulation to inform system design decisions, explore concepts of operations (CONOPS), and derisk critical aspects such as algorithms and processing architectures.

Responsibilities

• Define the radar digital twin scope, fidelity, interfaces, and validation approach
• Design, implement, and maintain end-to-end radar models (RF/propagation, signal chain, processing, detection/estimation) across the product development lifecycle
• Use modelling & simulation to inform system design decisions and trade-offs (e.g., waveform, antenna, processing, compute architecture)
• Explore CONOPS and wider system implications of radar function, including interactions with platform constraints and mission needs
• Derisk key design areas—such as algorithms, processing architectures, and performance margins—through targeted simulation studies
• Develop system-level performance assessments (e.g., coverage, detection metrics, tracking performance) and run sensitivity/what-if analyses
• Define model verification/validation methods, correlate models to test/measurement data where available, and quantify uncertainty
• Communicate results clearly to hardware, software, and systems stakeholders; document model assumptions, limitations, and evidence
• Establish modelling best practices (versioning, reproducibility, test cases) to enable repeatable decision-making and long-term maintainability

Requirements (Necessary)

• Degree in a STEM subject (typically Electronics, Physics, or similar), or equivalent practical experience
• Strong grounding in radar theory and core performance drivers
• Modelling & simulation experience, including defining models, assumptions, and validation approaches
• Working awareness of radar usage and context (e.g., algorithms, RF physics, and CONOPS considerations)
• Ability to translate ambiguous system questions into structured simulation studies and clear, actionable outputs

Preferred (Desirable)

• Deep technical knowledge of radar theory (e.g., waveform design, detection/estimation, clutter, propagation, interference)
• Experience undertaking and owning model-based projects end-to-end (requirements, implementation, V&V, stakeholder communication)
• Experience applying digital twin approaches within a technology-development programme
• Understanding of system-level performance assessment (e.g., coverage analysis, detection metrics, sensitivity analysis and uncertainty quantification)

About Us

We're building low-cost interceptors that defeat these threats, and the surveillance systems to detect and target them – at a cost taxpayers can afford, at the pace the threat demands, and with sovereign supply chains that assure delivery.

We have immense backing from the world's best venture funds, we’re building a company for the scale and urgency of the mission and we’re one of the fastest-growing defence technology companies in history. That demands exceptional people across every discipline—people who combine deep expertise with sound judgement, take ownership of difficult problems and turn ambition into results.

The standards are high. The work is demanding. The impact is real. If you want to build something that matters, join us.

Our Commitment to Inclusion
We’re committed to building a diverse and inclusive workplace. If you’re excited about this role but don’t meet every requirement, we still encourage you to apply.
