Battery Process Engineer information

What does a Battery Process Engineer do?

A Battery Process Engineer is responsible for designing, optimizing, and overseeing the manufacturing processes involved in producing batteries, such as lithium-ion cells. They work to improve efficiency, quality, and safety in battery production by developing and refining procedures, selecting appropriate materials, and troubleshooting issues. Additionally, they collaborate with teams across research, development, and manufacturing to scale up new battery technologies from prototype to mass production. Their role is critical for ensuring that batteries meet performance and reliability standards required for various applications, including electric vehicles and consumer electronics.

What is the difference between Battery Process Engineer vs Battery Manufacturing Technician?

AspectBattery Process EngineerBattery Manufacturing Technician
CredentialsBachelor's degree in engineering or related field; often requires experience in process designHigh school diploma or technical certification; on-the-job training
Work EnvironmentDesigning, optimizing, and overseeing manufacturing processes in labs or production facilitiesOperating machinery and performing manual tasks on the production line
Industry UsageInvolved in process development, quality control, and process improvementFocuses on assembly, equipment operation, and quality checks

The Battery Process Engineer focuses on designing and improving manufacturing processes, requiring technical expertise and engineering credentials. In contrast, the Battery Manufacturing Technician handles day-to-day production tasks, operating equipment and ensuring product quality. Both roles are essential in battery manufacturing but differ in responsibilities, skills, and work scope.

What are some common challenges faced by Battery Process Engineers during scale-up from laboratory to production?

Battery Process Engineers often encounter challenges when translating lab-scale processes to full-scale manufacturing, such as maintaining quality and consistency in large batches, optimizing equipment for high throughput, and ensuring safety protocols with reactive materials. These professionals must troubleshoot unexpected variations, coordinate closely with multidisciplinary teams (like R&D, quality assurance, and maintenance), and refine processes to meet both performance and cost goals. Effective communication and problem-solving skills are essential for overcoming these hurdles and ensuring smooth production ramp-up.

What are the key skills and qualifications needed to thrive as a Battery Process Engineer, and why are they important?

To thrive as a Battery Process Engineer, you need a solid background in chemical or materials engineering, experience with battery manufacturing processes, and often a relevant engineering degree. Familiarity with process simulation software (such as AutoCAD or MATLAB), Six Sigma methodologies, and data analysis tools is typically required. Strong problem-solving abilities, attention to detail, and effective communication skills help distinguish top performers in this field. These competencies are essential to ensure efficient battery production, maintain high quality standards, and drive innovation in the rapidly evolving energy storage industry.

Job description

Archer is an aerospace company based in San Jose, California building an all-electric vertical takeoff and landing aircraft with a mission to advance the benefits of sustainable air mobility. We are designing, manufacturing, and operating an all-electric aircraft that can carry four passengers while producing minimal noise.
Our sights are set high and our problems are hard, and we believe that diversity in the workplace is what makes us smarter, drives better insights, and will ultimately lift us all to success. We are dedicated to cultivating an equitable and inclusive environment that embraces our differences, and supports and celebrates all of our team members.
About The Role:
At Archer, we're scaling production of our High Voltage Electric Propulsion System - the heart of our eVTOL aircraft, which includes the High Voltage Battery, Electric Motor and Propeller assemblies and represents one of the most technically demanding, highly automated manufacturing systems in our factory.
We're seeking a Sr. Process and Equipment Engineer to play a critical role in keeping the powertrain manufacturing systems running at peak performance. This role sits on the Manufacturing Design Engineering group and owns the reliability, uptime, and continuous improvement of advanced powertrain manufacturing equipment in a high-volume production environment. You'll join the team that best matches your skills: HVPS, EPS, or Automation Controls.
You'll be hands-on, deeply technical, and accountable for solving complex manufacturing problems-often under real production pressure. The ideal candidate brings strong engineering judgment, a structured problem-solving mindset, and a bias for action. You'll own a core technical domain while expanding your impact across our automated equipment and manufacturing ecosystem.
We are open to candidates with a mechanical/process focus, controls/automation focus, or a strong blend of both.
What You'll Do:
  • Support high-volume production and respond to equipment and process escalations
  • Troubleshoot complex electromechanical manufacturing systems and drive containment, corrective actions, and long-term improvements
  • Lead root cause analysis and eliminate recurring failure modes impacting uptime and OEE
  • Provide hands-on technical leadership during extended downtime events
  • Own station- and line-level performance metrics and execute improvement projects
  • Lead equipment upgrades, repairs, and CAPEX projects with a focus on reliability and manufacturability
  • Develop and improve SOPs, work instructions, and standard processes
  • Partner with Production, Maintenance, Quality, and Product Engineering to resolve process deviations and non-conformances

What You Need:
  • Bachelor's degree in Mechanical, Electrical, Mechatronics, or Robotics Engineering (or equivalent experience)
  • 6+ years sustaining, commissioning, or optimizing equipment in a highly automated, high-volume manufacturing environment (aerospace, EV, or semiconductor manufacturing preferred)
  • Proven ability to improve manufacturing performance metrics such as OEE
  • Strong troubleshooting and structured problem-solving skills (e.g., 5 Whys, DMAIC, 8D)
  • Ability to read mechanical drawings and electrical schematics
  • Clear communicator with a high-ownership, bias-for-action mindset

Technical Depth:
You bring deep expertise in at least one area, with the expectation to grow into adjacent systems:
  • Equipment Design & Specifications
  • Process Development & MES
  • Controls / Automation (PLCs, industrial systems)
  • Robotics or advanced manufacturing equipment

Working knowledge of automated assembly, test systems, industrial sensors/actuators, and factory systems is expected and will deepen over time.
Bonus Qualifications:
  • Experience with eMotor or battery manufacturing
  • PLC platforms (Allen-Bradley, Siemens, Beckhoff)
  • Robotics, vision systems, or MES integration
  • NFPA 70E or RIA certifications
  • PFMEA development, NX, or Teamcenter experience

Please note that this job description is intended to provide a general overview of the position and does not include an exhaustive list of responsibilities and qualifications.
At Archer we aim to attract, retain, and motivate talent that possess the skills and leadership necessary to grow our business. We drive a pay-for-performance culture and reward performance that supports the Company's business strategy. For this position we are targeting a base pay between$152,100 - $190,100. Actual compensation offered will be determined by factors such as job-related knowledge, skills, and experience.
Archer is committed to provide a safe workplace and a safe aircraft. This is a safety sensitive designated role. Employment in safety sensitive positions is contingent on successful passage of a background check and is subject to pre-employment and random drug screening.
