MERITUS Talent are working with one of Europe's leading defence manufacturers for the recruitment of a Software Engineer with experience of C++/CUDA to join their Stevenage office on a full time basis. The inital assignment is for 12 Months and requires someone to be on site 5 days a week, although compressed working is available. PAying £75 per hour via Umbrella, due to security reasons the candidate must be a sole British national willing to undergo SC prior to starting the role

We’re looking for experienced Software Engineers to join a specialist team building a high-performance simulation engine. This is a hands-on C++ role focused on performance optimisation and working at the cutting edge of simulation and modelling for defence systems.

What you’ll be working on:

You’ll develop and improve an application-level C++ engine that handles:

  • Data processing and memory management

  • Managing clusters of computers running simulations

  • Linking together various models built in MATLAB/Simulink

The aim is to make simulations run faster and more efficiently, through low-level performance improvements—especially by getting the most out of CPU and GPU hardware (CUDA).

What we’re looking for:

You’ll need solid experience with:

  • C++ and CUDA programming

  • Object-oriented software design

  • GPU/CPU performance optimisation

  • Managing memory effectively

  • Writing clear technical documentation

Bonus points for:

  • Experience with network programming

  • Familiarity with MATLAB/Simulink

  • Understanding of RF systems or digital signal processing

  • Working in a configuration-controlled environment

  • Knowledge of continuous integration and automated testing

Important info:

  • This role is 100% on-site due to the nature of the work

  • You’ll be based at the Stevenage site

  • Candidates must be eligible for UK defence security clearance


If you're an engineer who enjoys squeezing every ounce of performance from your code and working close to the metal, this is a great opportunity to get stuck into challenging, meaningful work.
