Job description

As a Senior Process Engineer, you will own and drive yield, quality, and continuous‑improvement activities for the plating department, delivering measurable reductions in process cost‑of‑poor‑quality (COPQ) while ensuring products meet customer and specification requirements. This role leads root‑cause and cost‑reduction projects, establishes and maintains process controls and documentation (SOPs, FMEAs, process parameters), analyzes SPC and capability data, and partners cross‑functionally to resolve customer complaints and maintain EHS compliance.

What You Will Do

• Lead primary initiatives to improve yield and product quality, acting as the accountable owner for yield and quality KPIs and improvement projects.
• Plan and execute cost‑reduction and process improvement projects, tracking financial impact and sustaining gains.
• Establish, document, and maintain process parameters, Failure Modes and Effects Analyses (FMEA), and standard operating procedures (SOPs) to ensure consistent and controlled plating processes.
• Analyze Statistical Process Control (SPC) data, evaluate process capability, and take necessary actions to ensure processes operate within specification limits.
• Lead cross‑functional teams to investigate and resolve customer complaints, drive root‑cause corrective actions, and reduce process COPQ.
• Ensure plating operations comply with environmental, health, and safety (EHS) regulations and internal EHS procedures.
• Support the Mechanical/Manufacturing Engineering department on improvement activities tied to the plating department, including equipment, fixtures, and process flow improvements.
• Oversee and participate in all plating‑related activities to sustain process stability, quality output, and continuous improvement.
• Perform other duties as assigned by supervisor, leader, or Head of Department to meet business and operational needs.

Who You Are (Basic Qualifications)

• Bachelor’s degree in Engineering (Materials, Chemical, Mechanical, Metallurgy, or equivalent) or equivalent technical qualification.
• 3+ years of hands‑on experience in manufacturing or process engineering, preferably with plating/surface treatment or electrochemical processes.
• Practical experience with SPC, process capability analysis (Cp/Cpk), FMEA development, and writing/maintaining SOPs.
• Demonstrated problem‑solving skills (root cause analysis, corrective/preventive actions) and experience leading cross‑functional improvement projects.
• Familiarity with EHS requirements in chemical/process environments and ability to ensure regulatory and site compliance.

What Will Put You Ahead (Preferred Qualifications)

• Advanced degree (MS) in a relevant engineering discipline.
• Six Sigma (Green/Black Belt) or Lean certification and demonstrated application of DMAIC or similar methodologies.
• Direct experience with plating chemistries, bath control, and plating process equipment.
• Proven track record of delivering measurable cost savings and yield improvements in a manufacturing environment.
• Experience with quality management systems (e.g., ISO), MES/ERP systems, and statistical software (Minitab, JMP, etc.).
