Software Engineer - Model Engineering, Defence


Join our defence and national security business and you’ll be helping users plan and train to meet the most complex security threats in the world. Working alongside experts in AI and Machine Learning, computational modelling and distributed systems, you’ll be putting multiplayer technology to life-saving use.
Your mission is to build scientific models that support our entire product offering and facilitate next generation decision support. We are a friendly, relaxed & inclusive team with an ambition to take agent-based modelling to the next level. Unlike many teams, we are a mix of applied scientists and software engineers working very collaboratively both internally and with our Defence customers.
We build software models of social systems as goal-oriented actors operating on imperfect information, “digitally twin” physical environments and infrastructure, and obsess with modularity to recast complex systems as combinations of simpler systems. Our model engineers build robust, performant, scalable models that run in complex, realistic simulations to support users’ decision-making processes and solve our customers’ problems.

Area of impact

  • You will work closely with applied scientists to take prototypes and model designs into a production environment. The main languages we use are Python and C++.
  • Your role will involve developing and implementing algorithms which result in plausible modelling behaviour; building pipelines to extract, synthesise and integrate data from various sources, making it available to simulation engines and user interfaces; and building tooling that enables model developers to do their work quicker and better.
  • You will be implementing socio-technical models of real-world phenomena that allow our customers to better understand how individuals interact with physical, political, information and other systems.
  • Your work will contribute to building a next generation product which will help governments gain a richer understanding of their most critical problems through the power of virtual worlds.

We would like to hear from you if you identify with the following

  • You are an experienced software engineer with fluency in at least one relevant OO or functional programming language and the openness to learn and adapt to a variety of languages. We currently use Python and C++ a lot as well as many of the related tools and libraries.
  • You support and have a clear appreciation of the modern software engineering workflow & delivery mechanisms.
  • You are enthusiastic about continuously improving and rapidly developing new competencies.
  • You are able to effectively communicate with clients in person, in writing and with visualisation.
  • You have an interest in machine learning engineering (e.g. agent-based modelling, discrete-event simulation, system dynamics, bayesian networks, probabilistic programming, machine learning).

While we think the above experience could be important, we’re keen to hear from people that believe they have valuable experience to bring to the role. If you identify with the team and mission, but not all of our requirements, then please still apply. 
Due to the nature of this role, you will be expected to meet requirements associated with obtaining UK security vetting clearance; including an unbroken residency in the UK for the previous 5 years. If you think that this might be an issue for you, please let us know
