Spartronics is a leading electronics manufacturing and engineering services company supporting high-reliability customers in Aerospace & Defense, medical, industrial, and other demanding markets. Our Plaistow, NH facility builds complex products including EMS assemblies, HLA's (High-Level Assemblies) & Integration, box builds, and electromechanical systems. We are growing and looking for talented engineers who want to grow with us.

We are seeking a hands-on Senior Manufacturing Engineer who enjoys being on the production floor, solving problems, improving processes, and working directly with production, quality, operations, and customers. This is more than a traditional engineering role- you'll be directly involved in troubleshooting, NPI, DFM/DFA, process development, root cause analysis, engineering changes, and continuous improvement.

The ideal candidate brings hands-on experience with box builds, EMS/electronics manufacturing, and electromechanical assemblies, along with experience supporting Aerospace & Defense customers and regulated/high-reliability manufacturing environments.

What You'll Do

• Lead hands-on manufacturing engineering activities and solve problems directly on the production floor.
• Develop and improve processes for complex electronic and electromechanical assemblies and box builds.
• Support NPI, DFM/DFA, engineering changes, documentation, and production readiness.
• Drive root cause analysis, corrective actions, yield improvement, and continuous improvement.
• Partner with Production, Quality, Operations, Program Management, Supply Chain, and customers.
• Provide technical leadership and mentor other engineers.
• Help build the engineering organization as our Plaistow operation continues to grow.

Requirements

Citizenship Requirement- ITAR Regulations require all candidates be a US Citizen, US Permanent Resident, Political Asylee, or Refugee. We can not sponsor Visas.

What We're Looking For

• Bachelor's degree in Manufacturing, Mechanical, Electrical Engineering, or related field—or equivalent experience.
• 3-7+ years of hands-on manufacturing engineering experience, preferably in EMS or complex contract manufacturing.
• Proven experience with box builds, electronics/EMS, and electromechanical assemblies.
• Strong troubleshooting, root cause analysis, process improvement, and problem-solving skills.
• Experience with NPI, ECOs, BOMs, drawings, work instructions, and manufacturing documentation.

Preferred:

• Experience supporting Aerospace & Defense customers, including applicable customer, quality, regulatory, and compliance requirements.
• Strong communication skills and the ability to work effectively across functions.
• Most importantly, a hands-on mindset and desire to grow into an engineering leadership role.

Why This Role Matters:

This is an opportunity to make a visible impact on a growing operation. You'll be solving real manufacturing challenges today while helping shape the engineering organization of tomorrow. For the right person, this role offers a clear path to Manufacturing Engineering Manager and broader leadership responsibility as Spartronics continues to grow in Plaistow.
