I really don't think here's a need for a suspension 'designer'. I believe all practical, durable, manufactureable and repairable suspension designs have already been published. Even active fluids and magnetism. What you might need is someone to assemble a kinematics & compliance model to evaluate ride, handling, loads, mis-build, off-road, and maybe a few other criteria. That leaves, Nastran, Adams, Solidworks, SuspensionSim, DYNATUNE-XL, just to name a few. Then you need to plug you new idea into a vehicle model of some sort and evaluate it's prowess where it's expected to have superior performance. That usually involves 'Integration' meaning how does your anti-proton beam suspension fit into your starship concept.`
