About The Position

Lithios is seeking a Senior Manufacturing Engineer to provide technical leadership in the development, design, integration, and optimization of manufacturing processes, equipment, tooling, and assembly systems. This hands-on role partners closely with R&D, engineering, quality, operations, and vendors to ensure products are designed for manufacturability. The ideal candidate brings strong mechanical engineering and equipment design experience and can lead projects from early design reviews and prototyping through equipment development, validation, new product introduction (NPI), and production ramp-up. The role also drives continuous improvement, troubleshoots complex manufacturing issues, and provides technical guidance to engineers, technicians, and manufacturing personnel. This position reports to the Principal Electrode Manufacturing Engineer.

Requirements

  • Bachelor of Science in Manufacturing Engineering, Mechanical Engineering, or a related field.
  • At least 5 years of relevant experience.
  • Experience working cross-functionally with engineering, manufacturing, and suppliers.
  • Experience designing and implementing assembly processes, fixtures, or test systems.
  • Familiarity with lean manufacturing principles, yield improvement, and waste reduction.
  • Proficiency in CAD software and simulation tools.
  • Ability to work against tight deadlines without sacrificing detail or safety.
  • Strong interpersonal and organizational skills, and attention to detail.

Nice To Haves

  • Experience with fuel cell or electrolyzer systems.
  • Experience with CAD software such as SolidWorks or OnShape.

Responsibilities

  • Apply mechanical engineering principles to design, develop, modify, and integrate manufacturing equipment, fixtures, tooling, and automated systems.
  • Lead technical assessments of manufacturing build processes and equipment capabilities, identifying opportunities to improve robustness, manufacturability, reliability, and operational efficiency.
  • Drive Design for Manufacturing (DFM) and Design for Assembly (DFA) activities with Engineering and R&D teams, incorporating PFMEA, risk assessments, tolerance analysis, and manufacturing feedback early in product development.
  • Develop and maintain manufacturing processes, procedures, equipment specifications, work instructions, SOPs, and training plans for internal operations and contract manufacturing partners.
  • Oversee prototyping, testing, and validation of equipment, tooling, fixtures, and manufacturing processes to ensure robustness, reliability, safety, and compliance with applicable standards.
  • Provide hands-on support for equipment installations, tool changes, equipment conversions, modifications, troubleshooting, and process improvements.
  • Work directly with contract manufacturers, equipment suppliers, machine shops, and other vendors on equipment development, manufacturing improvements, NPI activities, and technical problem resolution.
  • Mentor and provide technical guidance to manufacturing engineers, technicians, assemblers, and cross-functional team members on equipment, processes, and manufacturing best practices.
  • Promote a safe, organized, and efficient manufacturing environment, emphasizing equipment safety, workplace organization, material utilization, and continuous improvement.
  • Perform other engineering and technical functions as required to support R&D, manufacturing, and product development activities.
