Systems Engineer (E4)

Proposed system solutions and component sizing with Rexroth mobile hydraulic and HV electric portfolio.

Specialized in the hydraulic systems: hydraulic pumps, motors, load-sensing systems, hydrostatic transmission, solenoid-controlled components, in compliance with safety standards (e.g., ISO 26262, ISO 13849 and ISO 19014).

Specialized in the HV platform: electric motors, inverters, DC-DC converters, OBC (DC/AC charging), hydraulics, BMS and integrated systems, compliance with IEEE/IEC requirements (J1772, CCS, ISO 15118, etc.).

Developed proposals for over 50 customer inquiries across 150+ unique application scenarios in the US market.

Provided on-site commissioning and software support to customers with CAN tools such as CANalyzer.

Lead trainings for customers, sales team, distributors on mobile hydraulic and software solutions.

Guide of team members to utilize 8D methods for systematic problem solving with data-driven methods.

A fully electric compact track loader (e-CTL) powered by a 700V battery, inventor of a system of integrated electric-hydraulic system enabling energy recovery with more than 40% potential savings.

A novel drive concept using a single open-circuit pump (eOC-Drive) to drive two motors with secondary control replacing hydrostatic transmissions resulting in reduced components (~-44%) and enhanced control.

Embedded software development with model-based systems engineering such as MATLAB/SIMULINK and AMESIM, HIL simulation of complex electric and hydraulic systems, system integration with CAN tools.

Conducted field testing under heavy-duty working conditions. Invented features were successfully validated by end users and OEM customers, such as Caterpillar, John Deere, Bobcat, etc.

Patents, publications and presentations of the developed prototypes at international conferences and journals.
