Process Engineer

Are you passionate about semiconductor fabrication, thin-film technologies and solving complex manufacturing challenges?

At Coherent, you will help develop and improve the processes used to manufacture advanced thin-film tunable filters. Working across both manufacturing and product development, you will play an important role in improving wafer and chip yield, reducing fabrication costs and shortening production cycle times.

This is a hands-on, on-site engineering position where your ideas and technical expertise will directly influence product performance and manufacturing excellence.

What You’ll Do

• Support manufacturing and development activities for thin-film tunable filters.
• Work with key fabrication processes, including:
  • Photolithography.
  • Wet and dry etching.
  • Thin-film deposition.
  • Wafer and chip metrology.
• Develop, optimise and document fabrication processes.
• Analyse wafer measurement data and resolve results that fall outside process capability.
• Identify opportunities to improve wafer and chip yield, quality and reliability.
• Reduce fabrication costs, waste and production cycle times.
• Apply Statistical Process Control to monitor performance and improve process stability.
• Operate, troubleshoot and support the repair of high-vacuum equipment.
• Investigate equipment failures and recommend component upgrades or modifications.
• Design mechanical components and systems using CAD.
• Produce detailed technical drawings and translate designs into effective manufacturing processes.
• Set up, operate and troubleshoot test equipment.
• Manage multiple technical priorities while delivering high-quality solutions within agreed timelines.
• Clearly communicate technical findings and complex concepts to colleagues across the organisation.

About You

• Bachelor’s degree in Electrical Engineering, Mechanical Engineering, Physics, Chemistry, Materials Science or another relevant technical discipline.
• At least three years of experience in semiconductor or thin-film device fabrication.
• Practical knowledge of thin-film fabrication processes and equipment.
• Hands-on experience with photolithography.
• Experience operating and troubleshooting high-vacuum equipment.
• Knowledge of equipment failure analysis, repair and component modification.
• Experience using Statistical Process Control.
• Ability to interpret wafer measurement data and resolve process-capability issues.
• Strong problem-solving skills and the ability to work with limited supervision.
• Effective interpersonal, communication and presentation skills.
• Ability to manage multiple programmes, priorities and deadlines.
• Proficiency in Microsoft Excel, PowerPoint and Word.

Desirable Experience

• AutoCAD or comparable computer-aided design software.
• Mechanical design and preparation of detailed engineering drawings.
• Wastewater Treatment certification.
• Hazardous Materials training.

Working at Coherent

This is an on-site position within a collaborative, hands-on engineering and manufacturing environment. You will regularly interact with colleagues across development, manufacturing, equipment and quality teams.

Occasional travel, off-site meetings or overtime may be required, with some flexibility in working hours to support business and production needs.

The role requires regular computer use, movement within office, laboratory and manufacturing environments, and occasional lifting of equipment or materials weighing up to 20 pounds.
