Control Testing Engineer - Morrisville/Raleigh, NC

About the role

You will own the test strategy for the full microgrid control stack — from PCS/BESS firmware and Unit Controller through RT, SCADA, and EMS. You will build and run HIL test benches on RTDS automate regression, and produce the evidence needed for UL 1741-SB, IEEE 1547-2018, and customer/utility acceptance.

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 customer specific factory and site acceptance tests (FAT/SAT)
• Support commissioning and field issues into regression cases

Minimum 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

Preferred Qualifications

• Cybersecurity test exposure (fuzzing protocols, IEC 62443 verification)
• Field commissioning experience on BESS / microgrid / utility-scale projects
