The Conformal Coating Engineer is responsible for the development, optimization, and control of conformal coating processes for printed circuit board assemblies (PCBAs). This role ensures product reliability and environmental protection by selecting appropriate coating materials, defining process parameters, and maintaining compliance with industry standards. The engineer collaborates with manufacturing, Quality, and design teams to ensure robust, repeatable coating processes that meet customer and regulatory requirements.

This is a 100% onsite role in Perry, Ohio (Cleveland Metro area).

• Use and understand Lean Manufacturing principles.
• Develop, implement, and optimize conformal coating processes (e.g., selective spray, manual spray, dip, and brush coating) for PCBAs.
• Select and qualify coating materials (acrylic, silicone, urethane, epoxy) based on application requirements such as temperature, humidity, chemical exposure, and electrical performance.
• Define process parameters including viscosity, cure profiles, coating thickness, masking strategies, and application methods.
• Troubleshoot coating defects such as bubbling, de‑wetting (fisheye), delamination, insufficient coverage, orange peel, cracking, and contamination.
• Establish inspection criteria and methods (UV inspection, thickness measurement, IPC standards compliance).
• Create and control manufacturing instructions and implement engineering changes to the production floor.
• Generate Standard Operating Procedures and establish scheduled maintenance for machines and equipment.
• Coordinate with Quality teams to ensure compliance with industry standards e.g. IPC‑CC‑830, IPC‑A‑610, J‑STD and MIL‑I‑46058 where applicable.
• Support New Product Introductions (NPI) by developing coating processes for new PCBA designs.
• Evaluate and implement automation solutions for conformal coating application processes.
• Manage relationships with material suppliers and equipment vendors.
• Perform root cause analysis and implement corrective and preventive actions (CAPA).
• Lead continuous improvement initiatives to enhance quality, yield, and throughput while reducing cost and scrap.
• Performs training of team members per Quality and Standard Operating Procedures and specialized manufacturing techniques.
• Participate in audits and ensure compliance with EHS (Environmental, Health & Safety) regulations.
• Advise and assist Product Engineering and Quality Engineering as required.
• Other duties as assigned.

To perform this job successfully, an individual must be able to perform each essential duty satisfactorily. The individual must maintain confidentiality and have good judgment. Candidate will be expected to excel in ethical standards and promote the same within the company.

• Education/Experience/Credentials:
  Bachelor's Degree or equivalent experience in Mechanical, Materials Science, Manufacturing Technology, Industrial, Electrical Engineering, or other relevant discipline. +2‑5 years preferred in electronics manufacturing with conformal coating of PCBAs or robotics with material science background. Hands‑on experience with selective coating systems and industrial automation. Familiarity with SMT and PCBA manufacturing processes.
• Language Ability:
  Excellent communication both written and verbal. Ability to read and analyze periodicals, business reports, correspondence and procedure manuals. Ability to write reports,…
