Senior / Principal Modelling & Simulation Engineer

Cirrus Selection; Harry Stoke; On-site; GBP 45,000 - 73,000; Full time

Job summary

Cirrus Selection in Bristol is seeking a serious Modelling & Simulation Engineer to work on meaningful, real-world systems across marine, aerospace, and defence programs. You will design and validate real-time models and contribute to high-impact projects.

You’ll use MATLAB / Simulink to build models at system and vehicle levels, define control algorithms, and collaborate with expert engineers. The role combines technical challenge with hands-on engineering in a hybrid work environment.

Qualifications

• Degree qualified in a related discipline preferably Aerospace Engineering, Mechanical Engineering, Electrical Engineering or Mathematics
• Strong grounding in modelling, simulation, and systems thinking
• Experience in Hydro-actuated systems, Electro‑mechanical actuated systems, Multi‑body simulation, and vehicle dynamics
• Confidence with tools like MATLAB / Simulink and version control
• The ability to think critically, not just execute tasks

Responsibilities

• Building and validating models at system and vehicle level
• Defining control algorithms and performance requirements
• Getting hands‑on with MATLAB / Simulink
• Collaborating with smart engineers who know their craft
• Presenting your work to clients who expect clarity, not waffle

Job description

Bristol | £45,000 – £72,500 | Hybrid

If you are a serious Modelling & Simulation Engineer who actually wants to work on meaningful, complex systems, not just tweak models in the corner, then this is worth your attention.

Our client is growing in a big way. They have new projects landing, capability expanding, and a clear need for engineers who can think, challenge, and deliver, not just follow process.

This isn’t theory, it is real engineering.

You will be working across high-impact programmes spanning marine, aerospace, defence, and emerging technology. From flight control systems, vehicle dynamics to submarine autopilots, you will be using and designing real-time models. The kind of work that sharpens your edge, quickly.

What you’ll actually be doing:

• Building and validating models at system and vehicle level
• Defining control algorithms and performance requirements
• Getting hands‑on with MATLAB / Simulink
• Collaborating with smart engineers who know their craft
• Presenting your work to clients who expect clarity, not waffle

What you’ll bring:

• Degree qualified in a related discipline preferably Aerospace Engineering, Mechanical Engineering, Electrical Engineering or Mathematics
• Strong grounding in modelling, simulation, and systems thinking
• Experience in Hydro-actuated systems, Electro‑mechanical actuated systems, Multi‑body simulation, and vehicle dynamics
• Confidence with tools like MATLAB / Simulink and version control
• The ability to think critically, not just execute tasks

And let’s be clear…

This will suit someone who’s either:

• Ready to step up into a more senior, broader role
  OR
• Already operating at Principal level and wants more impact, not more meetings

The Environment

Supportive | technical | genuinely collaborative | hybrid working

No fluff, no gimmicks; just proper engineering work, with people who take pride in doing it well.

You will need to be a British citizen, and eligible for UK security clearance.
