Battery Process Engineer – Li-ion Assembly & DOE

ENOVIX Corporation; Penang; On-site; MYR 120,000 - 180,000; Full time

Job summary

ENOVIX Corporation in Penang, Malaysia is seeking a Process Engineer to develop and industrialize next generation high energy density Li-ion battery processes. You will own degas, electrolyte fill, and adhesive dispensing with robust control, DOE-based experimentation, and transfer to high-volume production.

You will lead cross-functional teams, analyze CTQ metrics, and drive process capability, yield, and cycle-time improvements while maintaining QMS compliance and ensuring device integrity.

Qualifications

• Bachelor’s degree in Chemical Engineering, Materials Science Engineering, Physics, Chemistry, Mechanical Engineering or related field; 7+ years experience or Master/PhD preferred.
• Ability to analyze process data and summarize meaningful information.
• Strong program management skills: meeting deadlines and milestones; excellent written and verbal communication.
• Willingness to travel in future as needed.
• Independent and cross-functional teamwork to solve complex problems.
• Familiarity with SPC, DOE, FMEA and 8D methodologies.
• Experience in Li-ion battery design, development and scale-up is highly desired.
• Proven track record of process integration from R&D to high-volume manufacturing.

Responsibilities

• Own degas process—develop and qualify vacuum degas, final seal and trim recipes, optimizing vacuum profile and dwell time.
• Develop and qualify electrolyte fill processes; ensure dose accuracy, fill weight, and QC checks.
• Develop adhesive dispensing processes; control bead geometry, dispense pressure and cure profile.
• Characterize CTQ parameters across degas, fill and dispense; apply gauge R&R, SPC and Cpk targets.
• Collaborate with Equipment Engineering on tool capability and consumable life.
• Lead root-cause analysis for defects using FMEA and 8D methodologies.
• Support scale-up and transfer to high-volume production; improve cycle time and yield.
• Design and run DOE experiments to define process windows and optimize yield.
• Lead cross-functional teams to develop processes and tooling for next-gen cell designs.
• Analyze performance metrics with data tools (e.g., JMP).
• Create and maintain project plans and ensure on-schedule delivery.
• Deliver data-driven analyses and communicate results to stakeholders.
• Create and maintain Work Instructions, OCAP, FMEA and Control Plans per QMS.
