We are looking for a hands-on, PhD Chemical Engineer to work in our Sensor NPD Group to assist in the development of Gas Detection Sensors.  If you are the successful incumbent, you will be responsible for the design, fabrication, testing, and analysis of catalyst-based chemical sensors operated by resistive thermal elements, including integrated sorbent filtration. While reporting to the Engineering Manager-Sensor Development, you'll have the opportunity to participate in all phases of the product development, from ideation to post launch support. If working in a cooperative team environment with other chemical, electrical, mechanical and software engineers, project managers, operations staff, designers and technicians sounds appealing, then we want to hear from you!



  • Work with cross-functional, new product development teams to establish the design, performance, and cost requirements of catalyst-based resistive thermal chemical sensors.
  • Establish and implement test programs to fabricate and verify selection of the optimal resistive elements, ceramic and catalyst precursors, and/or adsorbent media for the sensing application.
  • Utilize and/ or develop safe, reliable methods to generate and verify explosive and/or toxic atmospheres using a variety of techniques.
  • Support manufacturing in startup of new designs as well as legacy catalyst-based resistive thermal chemical sensors, including attention to production testing and quality control.
  • Keep appraised of innovative relevant technologies by tracking technical journals, attending conferences, and networking with experts in catalysis, air-purification, ceramics, etc.
  • Lead sub-projects based on reaction engineering and adsorption, train technicians and interns in experimental techniques, and compose test plans, in writing if needed.
  • Present technical material to a variety of audiences.  Provide concise technical reports to support investigations and technical judgements. 


Special knowledge, skills, and ability Requirements:


  • Demonstrated fundamental knowledge of solid-gas phase reactions and the mechanisms of catalytic oxidation.
  • Demonstrated knowledge in many of the relevant technical topics, including: the fabrication and performance of heterogeneous catalysts, thick and thin film deposition especially on thermal elements, fabrication and testing of wire resistive thermal sensors, or MEMS analogues of thermal sensors such as micro-hotplates.
  • Experience with analytical tools such as BET surface area, chemisorption and catalyst dispersion determination, catalyst activity determination, TGA, FTIR, XRF, XPS, XRD, SEM, TEM, and Auger.
  • Knowledge of various sensor precursor materials including ceramic colloidal slips & slurries, noble metal salts, platinum-alloy fine wire, base metal salts, & various adsorbents including alumina, silica, and activated carbon, as well as material methods for their manipulation.
  • Familiarity with automated test systems and data collection such as Labview, and comfortable working with large data sets.
  • Working knowledge of statistics and awareness of techniques such as design of experiments.
  • Strong written and oral communication skills.
  • International/Domestic travel of up to 10%.


Education and experience required:

  • Bachelor’s degree in Chemical Engineering, Materials Science, Analytical Chemistry, Physics, Chemistry or related discipline, preferably from an ABET accredited program.
  • This position is available at two different career levels based upon experience, education, etc.:
    • Level I: 3 years relevant experience 
    • Level II: 5 years relevant experience 
  • MS degree may be substituted for up to 2 years of relevant experience.


  • MS or Ph.D. in Chemical Engineering, Materials Science, Analytical Chemistry, Physics, or Chemistry.
  • Two or more years of “hands-on” experience with the design, fabrication, testing, and performance of catalysts / sorbents and/or resistive thermal sensors.
