In this position... This is an opportunity to work in a research environment defining the next generation of emissions and aftertreatment simulation. As diesel and gas powertrains evolve toward hybridization and electrification, the underlying simulation infrastructure must be reinvented to keep pace. In this role, you will research and build the simulation architectures needed to integrate models of fundamentally new system concepts — including hybridized gas/diesel emissions controls and electrified aftertreatment components such as electric DPFs and electrically heated catalysts — well before they exist in any production toolchain.
