ABOUT REDWOOD MATERIALS

Redwood is localizing a global battery supply chain that seamlessly integrates recovery, reuse, and recycling — keeping critical minerals in circulation and driving the energy transition. Founded in 2019, we’re delivering low-cost and large-scale energy storage and producing battery materials in the U.S. for the first time, all from batteries we already have.
Manufacturing Engineer
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.

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

• 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
