Join EFT Mobility at a pivotal time as we revolutionize the future of electric transport, focusing on cutting-edge Electric Powertrain (EFT) solutions for high-reliability applications, including UAV power systems. We are a fast-growing, dynamic company where every engineer plays a direct, hands-on role in bringing our innovative, safety-critical products to life. If you thrive on ensuring product quality and solving complex, real-world problems, we want you on our team.
We are seeking a proactive and detail-oriented Senior Production, Fleet & Maintenance Engineer to bridge the gap between initial design and long-term product success. You will be the technical lead for our battery products once they hit the production line and the field. This role requires a detective mindset to solve field failures, a builder mindset to coordinate reworks, and a leader mindset to manage our battery fleet and manufacturing partnerships.
What is your Day to Day Mission:
• Engineering Change Management (ECM)
• Collaborate with the Engineering team and Contract Manufacturers (CMs) to analyze and validate hardware or process changes.
• Provide on-site or remote monitoring of change implementations on the production line to ensure zero loss in quality.
• Validation: Design and execute rigorous test plans to verify that changes meet safety and performance standards before customer shipment.
• Failure Analysis & Root Cause Determination
• Own the Field Return (RMA) process from technical arrival to resolution.
• Perform deep-dive teardowns and data analysis to identify root causes of battery failures.
• Coordinate with the design team to implement permanent fixes and ensure these improvements are integrated back into the active production line.
• Fleet & Lifecycle Management
• Manage the health and inventory of the internal battery fleet used for R&D, testing, and production support.
• Sustainability: Define the criteria for battery end-of-life and coordinate the logistics for recycling programs.
• Supervise and document the rework of internal battery packs to maintain peak testing capacity.
• Field Campaign Coordination
• Organize and lead large-scale rework or retrofit programs for battery sets already deployed in the field.
• Develop specialized tooling or instructions for field technicians to ensure reworks are performed safely and consistently.
