About the position

HTC Global Services is seeking a chemist or chemical engineer to join the Advanced Emissions team within Vehicle Propulsion Systems Engineering. This role is pivotal in evaluating and investigating after-treatment technologies for exhaust gas treatment in internal combustion engines. The successful candidate will have a strong background in chemistry and a deep understanding of catalyst function and durability. The position offers an opportunity to work closely with clients and contribute to their success while advancing your career with the latest emerging technologies. In this role, you will be responsible for characterizing materials used in catalyst substrates, particle filters, and exhaust assemblies. This includes performing various analyses such as Scanning Electron Microscopy (SEM), Coefficient of Thermal Expansion (CTE), shear strength testing, porosimetry, X-ray Fluorescence (XRF), X-ray Diffraction (XRD), and Brunauer-Emmett-Teller (BET) surface area analysis. You will also conduct catalytic activity evaluations of monolithic samples and full-size after-treatment systems, benchmarking supplier formulations for catalyst robustness and durability. Collaboration is key in this position. You will work alongside after-treatment test engineers, technical specialists, and catalyst coaters, as well as substrate suppliers to develop new concepts for after-treatment solutions. Additionally, you will collaborate with calibration teams and suppliers to support root cause determination and prevent recurrence of warranty emission issues or post-production in-use concerns, such as In-Use Verification Program (IUVP) and In-Use Compliance Program (IUCP). Your responsibilities will also include assembling and maintaining reactor and catalyst assemblies for testing and demonstrating function, validating laboratory results on vehicle applications through dynamometer and chassis rolls testing for emission demonstration, and analyzing vehicle emissions data to quantify the sensitivity of tailpipe emissions to after-treatment design parameters and operational noise factors.

Responsibilities

• Characterization of materials for catalyst substrates, particle filters, and exhaust assemblies, including SEM, CTE, shear strength, porosimetry, XRF, XRD and BET.
• Performing catalytic activity evaluation of monolithic samples and/or full size aftertreatment systems.
• Benchmarking supplier formulations for catalyst robustness and durability.
• Collaborate with aftertreatment test engineers, technical specialists and catalyst coaters and substrate suppliers on new concepts for aftertreatment.
• Collaborate with calibration teams, suppliers, and technical specialists to support root cause determination and prevent recurrence for warranty emission issues or post-production in-use concerns (e.g., IUVP/IUCP).
• General work to assemble and maintain reactor and catalyst assemblies for testing and demonstration of function.
• Validation of laboratory results on vehicle applications by dyno/chassis rolls testing for emission demonstration and analysis of on-vehicle function.
• Analysis of vehicle emissions data to quantify sensitivity of tailpipe emissions to aftertreatment design parameters and operational noise factors.

Requirements

• Minimum B.S. in Physical Sciences or Engineering (Chemistry, Physics, or Chemical Engineering).
• 3 - 5 years of experience in the combustion engine emissions field.
• Understanding of TWC function, failure modes, and sensitivity to inputs and noise factors.
• Experience with chassis or engine dynamometer facilities and an understanding of their operations concerning vehicle drive cycles, emission reports, and data collection using ATI Vision/ETAS.
• Sound technical knowledge of regulated emission requirements.
• Excellent written and oral communication skills.

Nice-to-haves

• Familiarity with programming software including LabVIEW and Matlab.
• Familiarity with emission measurement techniques including FID, FTIR, mass spectrometry, and x-ray analysis.
• 5+ years demonstrating the ability to analyze, plan, and solve sophisticated system problems as they relate to engines and emissions.
