Control Testing Engineer – Microgrid HIL & Validation

Delta-Electronics-; Plymouth Charter Township (MI); On-site; USD 120,000 - 180,000; Full time

Job summary

Delta Electronics Americas seeks a senior test engineer to own the test strategy for the full microgrid control stack, from firmware through EMS. You will build and run HIL test benches on RTDS, automate regression, and produce evidence for UL 1741-SB, IEEE 1547-2018, and customer/utility acceptance.

You will define test plans, execute cross-layer integration tests, and generate certification reports while supporting field issues and FAT/SAT processes for energy storage and microgrids.

Qualifications

• BS/MS in Electrical / Power / Control Systems Engineering; 4+ years (Senior: 7+) in controls testing, HIL, or commissioning.
• Hands-on with RTDS and/or OPAL-RT, including model build, I/O mapping, and amplifier interfaces (PHIL is a plus).
• Strong Python scripting; experience with one automation framework (pytest, robot, TestStand, LabVIEW).
• Working knowledge of Modbus TCP, IEC 61850 (GOOSE/MMS), DNP3 — and how to inject/simulate them in test.
• Familiarity with UL 1741-SB, IEEE 1547-2018, and FAT/SAT processes for energy storage and microgrids.

Responsibilities

• Design and operate HIL test benches using RTDS — model power systems, PCS/BESS, and grid scenarios.
• Define test plans for islanding, blackstart, ride-through (LVRT/HVRT/FRT), protection coordination, mode transitions, and EMS dispatch.
• Build automated regression: Python / TestStand / pytest pipelines integrated with Azure DevOps CI/CD; publish coverage and pass/fail dashboards.
• Run integration tests across different layers validate timing, data contracts, alarm propagation, and failover behavior.
• Generate certification evidence and test reports for IEEE 1547-2018, UL 1741-SB, and FAT/SAT tests for energy storage and microgrids.
• Support commissioning and field issues into regression cases.
