Thin Film Coating Engineer

“CVI Infrared Optics is a part of the IDEX Materials, Science and Solutions (MSS) platform. Besides our unique capabilities in manufacturing large optics from visible to longwave, we are backed by the combined capabilities of our platform. CVI offers a full spectrum of optical engineering, manufacturing, and assembly expertise. Together we can support all our customers with more engineering expertise, broader capabilities, and extensive manufacturing resources.

Since 1982, CVI Infrared Optics has been manufacturing advanced optical components for high performance optronics systems. We have become the leading experts in manufacturing and integration of large optics from visible, and near infrared, to longwave infrared, that can continuously perform in extreme weather climates and harsh conditions.

When you need robust optical components and assembly expertise for your mission critical application, we can provide world-class solutions.“About the Role We are seeking a highly skilled Thin Film Coating Engineer to join our growing engineering team. This is an exciting opportunity to play a key role in the development, optimisation, and production of advanced thin film coatings used in high-performance optical, electrical, and mechanical applications.

Working closely with R&D, Manufacturing, Quality, and Engineering teams, you will be responsible for developing robust coating processes, improving product quality, supporting production scale-up activities, and ensuring coatings consistently meet demanding customer specifications.

If you have a passion for vacuum coating technologies, process improvement, and solving complex manufacturing challenges, we'd love to hear from you.

Key Responsibilities Process Development & Optimisation Design and develop thin film coating stacks using modelling and simulation software such as Essential Macleod, TFCalc, or Opti Layer.

Develop and optimise deposition processes using technologies including PVD (sputtering and e-beam evaporation) and/or CVD.Plan and execute Design of Experiments (DOE) to establish robust process windows and improve process capability.

Support the transition of new coating designs from development into high-volume production.

Scale coating processes while maintaining performance, yield, and repeatability.

Quality & Continuous Improvement Establish and maintain Statistical Process Control (SPC) systems for key coating parameters.

Define and maintain quality standards for raw materials, in-process inspections, and finished products.

Lead continuous improvement initiatives using Lean and problem-solving methodologies to reduce defects and improve yields.

Support non-conformance investigations, Root Cause Analysis, CAPA activities, and Material Review Board (MRB) processes.

Ensure compliance with quality standards and management systems, including ISO 9001.Testing & Characterisation Analyse coating performance using spectrophotometers and other metrology equipment.

Support calibration, Gauge R&R studies, and maintenance of coating measurement systems.

Design and oversee environmental and reliability testing, including thermal cycling, humidity, adhesion, and durability assessments.

Verify coating performance against customer drawings and specifications.

Equipment & Manufacturing Support Support the operation, maintenance, and optimisation of vacuum deposition systems.

Troubleshoot coating equipment, vacuum systems, and process-related issues.

Develop and maintain Standard Operating Procedures (SOPs).Train and mentor technicians and operators on coating processes and best practices.

Leadership & Collaboration Provide technical leadership and guidance to technicians and engineers.

Work collaboratively across Engineering, Manufacturing, Quality, Supply Chain, and R&D teams.

Participate in regular production and quality reviews to drive improvements in productivity and quality.

Build strong working relationships with customers, suppliers, and external partners.

Health, Safety & Compliance Follow the site's comprehensive safety regulations, promptly report any risks, hazards or incidents, and ensure a safe workplace by adhering to all established protocols.

Support company values, ethical conduct and integrity in all activities.

What We're Looking For Essential Qualifications & Experience Bachelor's, Master's, or PhD in Materials Science, Physics, Chemical Engineering, or a related STEM discipline.

Minimum 5 years' experience working with industrial vacuum deposition systems.
