Senior Production, Fleet & Maintenance Engineer

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. 

What you bring to the team:

• Experience: 5+ years in battery systems, power electronics, or hardware product engineering. 

• Technical Skills: Experience with Battery Management Systems (BMS), failure analysis and hardware testing protocols. 

• Project Management: Ability to coordinate complex tasks between internal engineering teams and external manufacturing partners. 

• Communication: Strong ability to translate technical failure data into actionable engineering changes. 

Your Benefits: 

• Direct impact: See your contributions rapidly integrated from cutting-edge research into industrialized products, flying in the field within short development cycles. 

• Culture & Environment: A dynamic, fast-paced, and collaborative startup environment with flat hierarchies, efficient collaboration, and a strong emphasis on continuous learning opportunities. 

• Work-life Balance: We offer flexible work schedules, and 30 days of paid vacation each year to support your personal and professional life. 

• Lunch Benefit: We promote healthy eating and the well-being of our employees with a monthly lunch budget. 

• Mobility Benefit: With our mobility budget, we pay your “Germany Ticket” for work or personal use monthly. 

• Health & Wellness: We support your physical well-being with a company-subsidized eGym Wellpass membership, giving you access to thousands of gyms and sports facilities. 

• Language Courses: German isn’t your mother tongue? We sponsor German courses for you to quickly learn and integrate even more.
