Summary

Posted: Nov 14, 2018
Role Number: 200002110
Do you have a passion for invention and self-challenge? Do you flourish with pushing the limits of what is considered feasible? As part of our Battery Engineering group, you’ll help craft creative battery solutions that deliver more energy in smaller spaces than ever before. You’ll work across disciplines to transform improved hardware elements into a single, integrated design. Join us to innovate new battery technologies that continually outperform the previous iterations. By collaborating with other product development groups across Apple, you’ll push the industry boundaries of what batteries can do and improve the product experience for our customers across the world. Function as the subject matter expert for structural characterization of energy storage materials and systems with the use of X-ray/neutron scattering techniques. Develop methods based on project needs using XRD, in-situ XRD, beamline-based X-ray and neutron scattering techniques to develop deep understanding in materials and address failure mechanisms/root cause. As part of materials characterization team, you will be expected to get trained and support additional characterization techniques, review data from other analysts and coordinate the use of multiple techniques, to drive the projects by providing materials understanding and correlation between materials properties and performance in a system.

Key Qualifications

  • Ph.D. in physics, materials science, or related field (preferably with X-ray/neutron scattering as a part of graduate level studies)
  • At least 4+ years of hands-on experience (after PhD) in advanced structural analysis techniques including X-ray/neutron scattering
  • Deep knowledge of batteries, battery materials and their characterization by X-ray/neutron scattering methods
  • Demonstrated track record of in-situ and synchrotron measurements under different sample environments (temperature, pressure, mechanical load, electric field)
  • Preferably experienced with advanced X-ray/neutron scattering techniques including pair distribution functional analysis, X-ray/neutron imaging, SAXS, SANS, TXM/XANES and XAS as well as other laboratory characterization techniques.
  • Excellent written and oral communications skills

Description

•Acquire, analyze and interpret data using X-ray diffraction (ex-situ/ in-situ) for phase identification, Reitveld refinements, texture, residual stress analysis •Identify and define the right characterization techniques for submitted samples and execute focused characterization projects to drive root-cause analysis and a deep material understanding •Coordinate beamline-based characterization studies (X-ray/neutron scattering and imaging, pair distribution functional analysis, SAXS, SANS, TXM/XANES and XAS etc) studies with National Labs and user facilities •Get trained and support other materials analysis techniques to address needs from projects involving characterization •Interface with other departments including production and R&D to collaborate on projects involving characterization •Adhere to best of class lab practices: Maintain an organized and clean laboratory environment, ensure sample piece location is controlled, follow all lab safety regulations
