Description

About the Opportunity:
A leading UK engineering organisation is expanding its Real-Time Simulation & Experimentation capability and is seeking skilled engineers with strong C# or C++ experience in real-time, embedded, modelling, hardware-integrated or safety-critical environments.

This is not a web or IT development role. It is a hands-on engineering position that involves building simulation environments, integrating hardware, modelling system behaviours, and supporting real-world engineering activities across the full lifecycle.

Engineers from automotive, aerospace, rail, medical devices, robotics, industrial automation, energy, defence, or any other high-integrity engineering sectors will find their experience highly transferable.
What will you be working on?

You will join a multidisciplinary team creating real-time simulations and synthetic environments used to design, test, validate and train against complex engineered systems. Your work will include:

  • Real-time simulation & modelling (SIL/HIL, behavioural modelling)
  • Integration of hardware components with simulation frameworks
  • Building C# and/or C++ components for system representation
  • Developing digital twins and experimental test environments
  • Designing tools to support verification, validation & training
  • Creating visualisation and analysis tools for system behaviours

This is real engineering: modelling physics, behaviours, interfaces, and integrating hardware - not enterprise apps or websites.

Who We’re Looking For?
We are continuing to grow our software team across 2026 and welcome applicants from a broad range of engineering sectors, including:

  • Automotive - ADAS, powertrain, embedded systems, real-time control
  • Aerospace / Avionics - simulation, modelling, system testing
  • Rail & Transportation - signalling, control, safety-critical systems
  • Medical Devices - regulated software, embedded control
  • Robotics & Automation - motion control, real-time behaviour
  • Industrial / Manufacturing Automation - PLC, modelling, hardware integration
  • Energy / Renewables - control systems, digital twins

If you’re an engineer who codes - not a web developer - this role is designed for you.
Essential Skills & Experience

  • Strong experience with C# or C++ in engineering or real-time systems
  • Background in real-time, embedded, simulation or hardware-connected software
  • Experience with system modelling, system behaviour or control systems
  • Exposure to SIL/HIL, digital twins, hardware integration or simulation frameworks
  • Ability to produce robust, maintainable, well-tested code
  • Comfortable working within Agile methods and multidisciplinary teams

Desirable Experience

  • Experience in regulated or safety-critical environments (e.g., automotive, aerospace, medical, rail)
  • CI/CD pipelines
  • Understanding of system architectures and engineering principles
  • Experience with distributed simulation, tools or test automation

What’s On Offer?
This company offers leading benefits including bonus, fantastic combined pension contribution, potential for paid over time, Enhanced parental & family leave and much more!

Security Requirements
Due to the nature of the projects, this role requires British Citizenship and the ability to undergo BPSS pre-employment checks, with additional security vetting where required.
