Mainspring also partners with global energy leaders including AEP, NextEra Energy Resources, Schneider Electric, and more.

The core values that ground our work, guide our decisions, and connect us together:

• 
  
• Pragmatic Optimism
  
• Excellence without Ego
  
• Proactive Collaboration
  

While Mainspring is growing rapidly to scale production of its linear generators, quality is a crucial element to the success of our mission.  The Senior Quality Engineer serves as Mainspring Energy's on-site quality representative embedded at global contract manufacturer Monterrey facility. This role is the critical bridge between Mainspring Energy's engineering and quality organization and global contract manufacturer's local quality team, enabling and empowering the global contract manufacturer to meet Mainspring Energy's product quality, inspection, and test requirements. Rather than functioning as an individual contributor on the floor, this person leads through influence: equipping, aligning, and supporting the global contract manufacturer quality team to own and execute quality outcomes on Mainspring Energy's behalf.

• 
  

  Review and provide guidance on test plans and procedures developed or executed by global contract manufacturer; identify gaps and work with Mainspring Energy test engineering to resolve ambiguities before they impact throughput

  
  
  
• 
  

  Support global contract manufacturer in reviewing and accepting test data packages; coach the team on identifying out-of-tolerance conditions and escalating appropriately to Mainspring Energy test engineering

  
  
  
• 
  

  Facilitate rapid resolution of test anomalies by connecting global contract manufacturer test technicians with the right Mainspring Energy engineering and quality resources

  
  
  
• 
  

  Ensure global contract manufacturer maintains a compliant calibration program for all measurement and test equipment (M&TE) used in Mainspring Energy product acceptance

  
  
  
• 
  

  Lead cross-functional Root Cause Corrective Actions (RCCA) alongside internal software/test engineering teams to reduce automated test station faults and NTF (No Trouble Found) yields 

  
  
  

•
