About the role

  • The ideal candidate has deep experience working alongside both technical and commercial teams to integrate advanced battery solutions based on customer specifications.

Responsibilities

  • Support customer engagements from technical due diligence to RFx, design reviews, validation, sampling, and pre-production readiness
  • Develop and maintain application-specific documentation, including requirements matrices, compliance reports, and datasheets
  • Cell Validation & Test Support
  • Support cell-level validation plans performed by product engineering, covering electrical performance, cycling, safety, environmental robustness, and mechanical integrity
  • Coordinate with internal and external test partners to ensure repeatable, traceable, and standards-aligned testing
  • Lead failure analysis efforts for cell, process, or performance deviations using electrochemical, mechanical, and materials-based method s
  • Correlate failure modes to design choices, materials, process windows, or usage conditions
  • Drive corrective and preventive actions (CAPA) in collaboration with R&D, process engineering, and manufacturing teams
  • Our platform enables a wide range of battery shapes and form factors, unlocking new product designs and previously impossible applications.
  • This role owns the translation of customer use cases into clear technical requirements and closing the loop through data-driven feedback into design-of-experiments (DoE), product improvements, and roadmap decisions.

Requirements

  • 3-6+ years of experience in battery cell engineering, application engineering, or validation
  • Hands-on experience with battery cell qualification, test planning, and requirements verification

Nice to have

  • Experience with solid-state, lithium-metal, or advanced lithium-based battery systems
  • Prior customer-facing experience supporting custom battery solution s
  • Familiarity with requirements and lifecycle tools (e.g., JAMA, Polarion, Arena, Jira, Confluence)

Benefits

  • Leveraging proprietary thin-film and roll-to-roll manufacturing, Ensurge delivers safe, high energy-density batteries for applications in wearables, health tech, industrial sensing, and defense.
  • Ensure test coverage reflects real-world application conditions (duty cycles, temperature profiles, load cases, packaging constraints)
