Senior Vice President, Product Management

Oliver is product manager for VBS3 and all desktop training software in Bohemia Interactive Simulations as well as being a director of the UK office.

Prior to establishing the UK office of BISim in 2011, Oliver worked at QinetiQ for seven years in several roles, starting his career as a developer working on vehicle crew system software, before becoming a systems administrator and simulation engineer for QinetiQ and Boeing Defence UK. Oliver then became the lead COTS (Commercial off-the-shelf) simulation engineer for QinetiQ working on delivering training to MOD customers using VBS2 and other tools. Oliver’s work with VBS2 ranged from the delivery of in-service training systems, to the development of CCDs (Capability Concept Demonstrators). These CCDs showed the use of VBS2 and other COTS products to deliver training traditionally delivered by high-cost bespoke systems. A constant component of Oliver’s roles was research and development, taking new software and hardware techniques and assessing their suitability in training solutions.

As a result of this work, Oliver was seconded to Niteworks (a UK government research and decision support agency) to work as the Technical Lead on several of the MOD’s training transformation programs which looked at filling training needs using modern COTS-based technology.
