Process Engineer

Role Overview

The Process Engineer is responsible for developing, supporting, validating, and continuously improving manufacturing processes after SMT assembly, including Conformal Coating, Dispensing, Potting, Mechanical Assembly, Box Build, Depaneling, Torque, Press-Fit, Labeling, and Packaging operations, DIP.

This position works closely with Engineering, Quality, Production, Maintenance, NPI, and customer teams to ensure backend processes are capable, repeatable, efficient, and compliant with customer and quality requirements. The ideal candidate has strong hands-on manufacturing experience, understands electronics assembly and mechanical integration processes, and can develop fixtures, define process parameters, troubleshoot manufacturing issues, and drive continuous improvement.

Key Responsibilities

Backend Process Engineering

• Develop, validate, maintain, and optimize backend manufacturing processes including Conformal Coating, Dispensing, Potting, UV/Thermal Curing, Mechanical Assembly, Box Build, Torque-Controlled Assembly, Press-Fit, Depaneling/Route, Labeling/Marking, and Packaging, DIP.
• Define and control process parameters, recipes, sequences, and acceptance criteria.
• Develop assembly methods, workstation requirements, tooling, fixtures, and manufacturing sequences.
• Troubleshoot backend manufacturing defects and process-related production issues.
• Improve quality, productivity, ergonomics, cycle time, scrap, and rework.

Conformal Coating & Dispensing

• Develop and optimize coating programs, spray paths, masking methods, coating thickness, and curing parameters.
• Support dispensing and potting process development, material handling, mixing, application, and curing requirements.
• Troubleshoot coating, dispensing, adhesion, curing, and material-related defects.

NPI & Engineering Support

• Support prototype builds, NPI activities, pilot builds, and production launches.
• Review product designs and provide Design for Manufacturing/Assembly (DFM/DFA) recommendations.
• Develop process flows, work instructions, tooling requirements, and manufacturing documentation.
• Participate in PFMEA, Control Plan, root-cause analysis, corrective actions, process qualification, and production readiness reviews.
• Work with Maintenance Engineering on equipment-related issues while maintaining ownership of process parameters and manufacturing requirements.

Quality, Documentation & Continuous Improvement

• Analyze recurring defects and manufacturing trends and lead or support root-cause and corrective/preventive action activities.
• Support internal and customer quality audits and ensure processes comply with customer, engineering, quality, and workmanship requirements.
• Develop and maintain Work Instructions, SOPs, Process Specifications, Process Parameters, Troubleshooting Guides, PFMEA, Control Plans, and engineering documentation.
• Support Lean Manufacturing and continuous improvement initiatives.

Qualifications

• Experience:

• 5+ years of experience in electronics manufacturing, backend manufacturing, mechanical assembly, process engineering, or related manufacturing engineering activities.
• Experience with Conformal Coating, Assembly, Box Build, Dispensing, Potting, or related processes preferred.
• EMS experience strongly preferred.

• Education: Associate or Bachelor's degree in Manufacturing Engineering, Mechanical Engineering, Industrial Engineering, Mechatronics, or a related technical field, or equivalent hands-on manufacturing experience.

• Technical Skills:
