C# Simulation Engineer

C# Real-Time Simulation Engineer

Bristol or Stevenage | Hybrid (2–3 days onsite)

The role

You will develop real-time, performance-critical simulation software used to model complex defence systems (e.g. missile systems, sensors, and system interactions).

Your work will:

• Run under real-time constraints where timing and determinism matter
• Interface with hardware-in-the-loop rigs and test environments
• Support verification, validation, and demonstration of physical systems
• Contribute to distributed simulation environments used across engineering teams

What you’ll need

• Strong C# software engineering experience in a real-time or performance-sensitive context
• Experience with real-time systems, simulation, or systems modelling
• Solid understanding of:
• Multithreading / concurrency
• Performance optimisation
• Software design for deterministic systems
• Experience working in:
• Agile environments
• Test-driven development / unit testing
• CI/CD pipelines

Ideal backgrounds

We are particularly interested in candidates from:

• Defence, aerospace, automotive, or a transferrable industry
• Real-time / embedded systems engineering
• Simulation or modelling of physical systems
• High-performance or low-latency software development

What you’ll get

• Bonus up to £2,500
• Pension matched up to 14%
• Paid overtime opportunities
• Onsite facilities (subsidised meals, free parking)
• Enhanced parental leave (up to 26 weeks)

Why this role is different

This is an opportunity to work on engineering-grade software, not business systems. Your code directly contributes to real-world system behaviour, testing, and validation of advanced defence technology.
