About the Role – Manufacturing Production Engineer
Peak Energy is seeking a Manufacturing Production Engineer to support day-to-day production at our Sacramento factory. This role sits between process engineering and equipment sustaining. You will be on the floor, troubleshooting equipment and process issues in real time, working with production to improve OEE, and driving mechanical and process improvements on the machines and lines you own.
What You’ll Do (Responsibilities)
Troubleshooting & Production Support
- Serve as a front-line technical responder for equipment downtime and process disruptions on the production floor, coordinating with maintenance teams.
- Drive root cause analysis on equipment and process failures and own corrective and preventive actions through closure across mechanical, pneumatic, and electrical scopes.
- Build out and maintain equipment documentation: PM schedules, spare parts lists, troubleshooting guides, and work instructions.
- Manage spare parts inventory and vendor relationships for critical equipment components.
- Partner daily with production supervisors and operators to track and improve OEE (availability, performance, and yield) through improvement projects.
