Systems Simulation Engineer; C# ​/RealTime

Position: Systems Simulation Engineer (C# / Real‑Time)
Location: Hertfordshire

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
