Sr. Materials Engineer, Composite Film Development

What to Expect

This engineer will lead the integration of next-gen materials via electrode process development, understanding and leveraging material behavior to enhance the performance of thin composite films for energy storage applications. This hands-on role combines advanced materials science, rheological expertise, and electrochemical understanding to solve complex challenges through first-principles research. You'll manage multiple projects, iterate rapidly, and deliver results in a collaborative, cross-functional setting.

What You'll Do

• Design and optimize binder/active/inactive materials incorporation for composite films, focusing on melt mixing, extrusion, solution casting, and lamination processes
• Investigate structure-property relationships to address performance gaps in energy storage systems
• Collaborate with cross-functional teams (e.g., electrochemical, mechanical, process engineering) to translate lab findings into scalable solutions
• Optimize mechanical, electrochemical, and material properties to improve composite thin film performance
• Manage end-to-end project timelines, balancing hypothesis-driven research with operational agility
• Document experiments, analyze data, and communicate insights to stakeholders

What You'll Bring

• Degree Materials Science, Polymer Materials Science, Polymer Engineering, or equivalent experience
• Proven expertise in composite thin film development (cast, melt processing, solution casting, or analogous techniques)
• Deep understanding of polymer rheology, processability, and composite integration
• Strong electrochemical background with experience in energy storage systems is a plus (e.g., batteries, supercapacitors and proficiency in electrochemical testing methods e.g., EIS, CV, galvanostatic cycling)
• Proven experience in mechanical property evaluation of polymeric films and composites (e.g., tensile testing, DMA, adhesion analysis)
• Demonstrated ability to manage multiple projects and deliver results in a fast-paced R&D environment
• A self-starter capable of navigating complex, multifaceted challenges with adaptability and precision
• Strong collaborator with a proven ability to work effectively in cross-functional teams
• Passion for merging fundamental materials science with real-world engineering
• A strategic thinker capable of aligning short-term objectives with long-term technological vision
