We are a technology company with a proud history working with Defence, Government and business in the UK and around the world. Our long-term customers include high-level Government departments, which rely on us to provide services and systems that are critical to our national security and defence. This is an opportunity to make an impact on a team that takes great pride in delivering the very best solutions in a role that really does 'make a difference' of critical importance and as a software engineer you can expect to be involved in supporting ongoing maintenance and enhancement of mission-critical simulation software working as part of a dedicated team. Activities will include capture and analysis of requirements or other change requests, design and development of the associated code, testing, analysing and updating the software and documentation, contributing to quarterly reports on development and testing activities, managing configured data and delivering each version on an annual release cycle. The simulation software runs in a Windows environment, and is crucial to defence decision making. The role requires contributing to a rigorous development and test cycle that maintains high customer confidence in both the software and the team maintaining it, and developing modelling solutions to real-world developments. There is also an element of study work, using the software to carry out parametric study to answer customer questions or optimise modelling. The successful candidate will be a confident C++ practitioner, with the ability to work effectively with a demanding customer. The role is based in Wiltshire but may involve occasional travel both within and outside of UK.
