Quality Assurance Specialist

MAC Products is a third-generation, family-owned manufacturer in Kearny, NJ serving the rail transit electrification and electrical utility industries. We are a small, specialized company — and that means the people we hire have real impact. We are looking for a Quality Assurance Specialist who is ready to take ownership of our core quality systems, work shoulder-to-shoulder with our inspection team, and help us scale quality operations to match our growth.

This role reports directly to the Quality Manager and is a clear path to Quality Engineer for the right candidate. It's the right fit if you are a problem-solver with solid QMS knowledge, good with people, and someone who gets things done.

This is a full-time, on-site position (Monday–Friday, Kearny NJ).

What You'll Do

• Own CAPA and nonconformance management — open, track, investigate, and close corrective and preventive actions from initiation to verification of effectiveness.
• Manage customer complaint intake, coordinate root cause investigations, and drive corrective action responses.
• Support and guide QC inspectors on daily questions, inspection decisions, and documentation — acting as a resource and sounding board for the inspection team.
• Maintain and improve quality system documentation: procedures, work instructions, forms, and inspection records.
• Support internal audit activities and help maintain compliance with ISO 9001:2015.
• Assist the Quality Manager in compiling quality metrics and preparing data for leadership reporting.
• Collaborate with manufacturing and engineering to identify process gaps and implement practical improvements.

What We're Looking For

Required:

• 3–5 years of experience in a quality role within a manufacturing environment.
• Working knowledge of ISO 9001:2015 and quality management system fundamentals.
• Hands-on experience with CAPA processes — not just familiarity, but actual ownership.
• Strong interpersonal and communication skills — comfortable working with inspectors, operators, engineers, and management.
• Organized, self-directed, and capable of managing multiple open issues simultaneously.
• Proficiency with Microsoft Office Suite.
• Must be a U.S. citizen or permanent resident.

Preferred / Big Plus:

• Associate's or Bachelor's degree in a technical or quality-related discipline.
• Experience in a supervisory or lead quality role.
• Familiarity with welding, brazing, or electro-mechanical assembly processes.
• Exposure to customer complaint management systems or quality software (e.g., Unipoint, ETQ, or similar).

Why MAC Products?

• Direct impact: small team, real ownership — you won't be filing paperwork for someone else's decisions.
• Niche industry in rail transit and electrical utility — specialized, stable markets.
• Clear growth path: this role is designed to develop into a Quality Engineer position.
• Collaborative culture where leadership listens and good ideas move fast.
