Test Engineer (2nd Shift)

About the role

Sanmina Corporation is a leading integrated manufacturing solutions provider serving fast‑growing segments of the global Electronics Manufacturing Services market. The Test Engineer conducts routine electrical, mechanical, and high‑voltage diagnostic testing on Medium Voltage (MV) transformers and power distribution equipment, supporting late‑day manufacturing workflows to ensure finished products comply with IEEE, IEC, ANSI, and NEMA safety and quality specifications prior to release.

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 and induced over‑voltage withstand testing, while maintaining full adherence to safety margins.
• Execute tests during evening shifts to keep production timelines on track, maintain detailed pass/fail logs, and lead shift handovers communicating technical non‑conformances.
• Process raw measurement data, cross‑reference against design specifications, and draft preliminary Certified Test Reports using standard templates.
• Identify initial test failures, document symptom profiles, perform basic root‑cause diagnostics, 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 PPE, Lockout/Tagout (LOTO) procedures, and zero‑energy state verifications.

Requirements

• Bachelor’s degree in Electrical Engineering (BSEE) or Electrical Engineering Technology (BSEET); recent graduates are encouraged to apply.
• 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).
• Must be able to consistently work a dedicated 2nd‑shift schedule.

Qualifications

• 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 equipment).
• Working knowledge of industry standards such as IEEE, IEC, ANSI, and NEMA.
• High attention to detail, clear written and verbal communication for shift handoffs, strong analytical skills, and adaptability in an active manufacturing environment.

Schedule

2nd Shift: 3:00 PM – 11:30 PM (flexible evening hours).
