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

• 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 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.
