James graduated from the University of Cape Town in 2008 with a first class honours degree in mechanical engineering. His prior experience included a period with Hatch Africa where he was involved with specification for contractor tendering and the installation of gas engines. James was subsequently employed as an engineer by Reitech SA, where he integrated new machines and conveyors, and did 3D modelling, sheet metal design and factory layout. At Unique Hydra, a manufacturer of offshore diving equipment, he designed a damping mechanism for a hyperbaric chamber door and performed fatigue calculations for dive cage recovery units. After joining CapeRay in 2015, James was responsible for mechanical engineering design and testing, in particular the hermetically-sealed breast platform (HSBP) for Aceso, and in 2020 the mechanical design of their new product called Epione, that is an automated breast ultrasound (ABUS) device. He left CapeRay at end-2020 to join local manufacturer GMS Systems, and continues to consult to them.
