• Research Collaboration:
  Ensure novel ideas are feasible and smoothly embedded into existing workflows

• Creative Problem Solving:
  Apply fresh, unconventional approaches to overcome process challenges

• Project Management:
  Navigate complex, multi‑team environments—coordinate between process and product development, systems engineering, and quality control; negotiate priorities and drive projects forward

• Documentation & Reporting:
  Maintain clear records of process changes, test results, and development milestones

What you bring:

• Bachelor’s or Master’s in Materials Science, Electrical Engineering, Chemical Engineering, Nanotechnology, or equivalent experience
• Proven, hands‑on background in high‑tech fabrication or manufacturing (3+ years)
• Strong analytical mindset and practical fabrication skills
• Excellent communication and cross‑team coordination abilities

Bonus points for:

• Experience in cleanroom‑style environments or dust‑controlled labs
• Familiarity with chemical PCB or Semicon processes
• Formal training in Six Sigma/Lean or Design of Experiments
• Prior work with flexible substrates or cryogenic materials
