  • Develop and optimize manufacturing processes for robotic subassemblies and full systems, with a focus on repeatability, efficiency, and scalability.
  • Collaborate with design engineering teams to ensure DFM principles are applied early in the product development lifecycle.
  • Plan labor requirements and takt time for cell-based manufacturing environments.
  • Design and implement quality control procedures and inspection methods to ensure robust manufacturing outputs.
  • Support continuous improvement initiatives through root cause analysis, process audits, and corrective action planning.
  • Document work instructions, standard operating procedures (SOPs), and process flows.
  • Work closely with operations, quality, and supply chain teams to ensure seamless production readiness.
  • Assist in ramping up production from prototype to low- and high-volume builds.

Qualifications:
  • Bachelor's degree in Mechanical Engineering, Industrial Engineering, Manufacturing
  • Engineering, or related field.
  • 3+ years of experience in manufacturing process development or related engineering
  • roles.
  • Strong understanding of DFM principles and experience working closely with product
  • development teams.
  • Hands-on experience with process documentation, time studies, and labor planning.
  • Proven ability to implement quality control systems in a manufacturing setting.
  • Experience in cell manufacturing environments is highly desirable.
  • Familiarity with robotic systems, automation, or electromechanical assemblies is a plus.
  • Excellent problem-solving and communication skills.
  • Preferred Skills:
  • Experience with manufacturing execution systems (MES) or digital manufacturing tools
  • Proficiency in CAD and statistical process control (SPC) tools
  • Background in early-stage hardware startups or fast-paced R&D environments

Benefits:
We provide market standard benefits (health, vision, dental, 401k, etc.). Join us for the culture and the mission, not for the benefits.
Salary:
$140, 000 - $180,000.00
