Materials Chemistry Engineer

该职位来源于猎聘 Job Description

• Design and optimize Fe-based soft magnetics, amorphous, and nanocrystalline alloy powders for high frequency inductors.
• Engineer surface treatments to develop organic and inorganic coating chemistries to improve the materials performance.
• Engineer particle size distribution, morphology, and microstructure to meet electrical and thermal performance targets.
• Conduct alloying, doping, and compounding studies to tune permeability, coercivity, losses and saturation flux density.
• Perform magnetic characterization (VSM, B H loops, AC loss) and correlate results with component performance.
• Collaborate with electrical design teams to co optimize materials with the desired component architectures.
• Lead root cause analysis for material related reliability issues (oxidation, aging, thermal drift).
• Support supplier qualification and scale up of powder production. Job Qualification:
• M.S. in Materials Science, Chemistry, Metallurgy, or related field.
• ≥7+ years of experience in soft magnetic materials, powder metallurgy, or soft magnetic components.
• Strong understanding of Fe based alloys, amorphous/nanocrystalline materials, and surface chemistry.
• Hands on experience with coating processes: sol gel, silane coupling, phosphating, polymer and oxide metals encapsulation,
• Familiarity with high frequency power electronics in POL modules.
• Experience with DOE, SPC, and materials reliability testing.
