Test Engineer (2nd Shift)

Summary

Sanmina Corporation is an integrated manufacturing solutions provider serving the global Electronics Manufacturing Services market. The Test Engineer conducts electrical, mechanical, and high-voltage diagnostic testing on medium-voltage transformers and power distribution equipment, processes test data, troubleshoots failures, verifies test equipment, and supports evening-shift production workflows.

Responsibilities

• Perform core electrical tests on MV transformers, including winding resistance, insulation resistance, Turns Ratio (TTR), vector group verification, excitation current, and no-load/load loss measurements
• Assist in executing high-voltage dielectric tests, such as applied voltage (separate source) and induced overvoltage withstand testing, maintaining full adherence to high-voltage safety margins
• Execute tests during evening shifts to keep production timelines on track. Maintain detailed pass/fail logs and lead shift handovers to communicate technical non-conformances to daytime engineering teams
• Process raw measurement metrics, cross-reference output against design spec sheets, and draft preliminary Certified Test Reports using standard templates
• Identify initial test failures, document symptom profiles, perform basic root-cause diagnostic evaluations, and escalate structural or design defects to senior test engineers
• Perform pre-shift functional checks and calibration verifications on test instruments (power analyzers, insulation sets) to ensure test bays remain compliant and ready
• Follow high-voltage safety practices, including mandatory Personal Protective Equipment (PPE) utilization, Lockout/Tagout (LOTO) procedures, and zero-energy state verifications

Skills

• * **Education:** Bachelor's degree in Electrical Engineering (BSEE) or Electrical Engineering Technology (BSEET)
• Entry level candidates encouraged to apply
• * **Experience:** 0-2 years of relevant experience (academic lab work, co-ops, or internships in power engineering, electrical machines, or high-voltage systems are highly valued)
• * **Availability:** Must be able to consistently work a dedicated 2nd shift schedule. (3:00 PM - 11:30 PM Flexible Evening Hours)
• + Knowledge of transformer operations, electromagnetic theory, and 3-phase power distribution circuits
• + Familiarity with electrical test instrumentation (e.g., Megger, Doble, Omicron, or similar diagnostic test equipment)
• + Working knowledge of industry standards (IEEE, IEC, ANSI, NEMA)
• High attention to detail, clear written/verbal communication for shift handoffs, strong analytical skills, and adaptability in a active manufacturing environment
