Currently leading the development of production level motion controls software for Hyliion's Karnot Engine. The engine consists of 4 simultaneously oscillating linear motors coupled to heat exchange systems (sterling) to drive the energy production of the stationary generator. The novel system uses flameless oxidation rather than combustion events to move the shafts.Previously lead the design and development of advanced control strategies for Class 8 truck hybrid powertrain to improve energy management, fuel efficiency, product reliability and serviceability.•Leverage advanced control theory, signal processing and statistical analysis to identify opportunities to create new control concept and optimize of existing control algorithms.•Support the development of real time hybrid controller to meet production schedule and resolving issues on time.•Support simulation and modeling team for proper component sizing and vehicle performance target setting.•Ensure that Hardware and Software aspects of Hyliion products meet all necessary safety and emission compliance requirements.•Work with software and hardware engineers in a collaborative product development team environment to architect, design and implement Best-In-Class Electrification products.•Efforts will include creating requirements, specifications and test documents with Safety, Testing and Quality as critical elements from the start.•Provide necessary training to improve team competency.•Assist with utilities development for data analysis and visualization.
