This is a highly transparent role working at the intersection of sophisticated hardware, process engineering, and manufacturability—where your decisions matter.

Requirements

• Experience as a manufacturing or process engineer supporting complex capital equipment in ultra‑clean environments (e.g., Class 100 cleanrooms, AMC‑controlled environments).
• Strong ability to read and interpret technical drawings, understand bills of materials (BOMs), and use precision testing and measurement tools.
• Proven technical writing, documentation, and cross‑functional interpersonal skills.
• Hands‑on experience with ultrasonic cleaning systems, plasma cleaning hardware, bake chambers, and/or residual gas analyzers (RGA).
• Experience working in ultra‑clean vacuum environments.
• Knowledge of UV optical component cleanliness, cleaning, and handling practices.
• Experience applying SPC or similar methodologies in a manufacturing environment.
• Demonstrated ability to develop new processes from concept through production ramp with manufacturability and scalability in mind.
• Requires a Bachelor's degree and a minimum of 2 years of related experience; or an advanced degree without experience; or equivalent work experience.

Responsibilities

• Own the development, optimization, and sustainment of ultra‑precision cleaning processes and cleanliness standards for advanced capital equipment.
• Qualify and support precision cleaning equipment and processes to meet stringent EUV and system‑level cleanliness requirements.
• Partner closely with Design, Process, and Manufacturing Engineering teams to influence clean hardware design and ensure manufacturable, production‑ready cleaning solutions.
• Lead the introduction of new cleaning methods and technologies with scalability, adaptability, and cost of ownership in mind.
• Train and support manufacturing personnel in the accurate use, maintenance, and troubleshooting of ultra‑precision cleaning equipment and procedures.
• Drive continuous improvement initiatives passionate about cleanliness, yield, reliability, and long‑term system performance.
• Develop and maintain high‑quality technical documentation, work instructions, and best‑known methods.
• Apply statistical process control (SPC) and data‑driven techniques to monitor, control, and improve cleaning process capability.
