Manufacturing Engineer, Energy Storage
Essential Duties:
We are looking for a highly capable and hands-on Manufacturing Engineer to drive the development, optimization, and scaling of production lines for a complex high-voltage system. This system includes high-power electronics, thermal components, and electromechanical integration. You'll work closely with CMs, test engineering, and product design teams to scale cost-effective, high-yield processes.
Responsibilities Will Include:
- Define manufacturing process flows, build station-level process documentation, and create tooling and fixture requirements for product assembly and test
- Partner with CMs to bring up new lines, run capacity models, and validate takt times, throughput, and line balance
- Troubleshoot issues on the line and drive corrective actions for yield, first-pass success rate, and build quality
- Own DFM and DFT efforts, providing clear, actionable feedback to engineering
- Collaborate with quality and test engineering to ensure process stability, traceability, and defect containment
- Analyze production data and develop dashboards to identify trends, bottlenecks, and cost-reduction opportunities
- Develop ramp plans and execution tracking for NPI and scale transitions
Desired Qualifications:
- B.S. in Mechanical, Electrical, or Manufacturing Engineering (or related)
- 3+ years of experience in production support or NPI for high-power electronics or electro-mechanical assemblies
- Strong technical knowledge of SMT, reflow, box build, mechanical assembly, and HV safety processes
- Ability to write and maintain SOPs, work instructions, and training document
- Experience working with CMs on high-volume production environments
- Familiarity with MES systems, Python/SQL for data extraction, or Lean Six Sigma certification
Physical Requirements:
- Ability to perform the essential job functions consistent safely and successfully with the ADA, FMLA and other federal, state and local standards, including meeting qualitative and/or quantitative productivity standards
- Ability to maintain regular, punctual attendance consistent with the ADA, FMLA and other federal, state, and local standards
Working Conditions:
- Environment, such as office or outdoors
- Ability to work in challenging working conditions which may include exposure to noise, dust, chemicals, and temperature extremes, while protected by PPE, for extended periods of time
- Essential physical requirements, such as climbing, standing, stooping, or typing
- Occasional work weekends, nights, or be on-call as a regular part of the job
