Role Summary:
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.
Key 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 / Test Stand / pytest pipelines integrated with Azure Dev Ops 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.
Required 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, Test Stand, 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 Cybersecurity test exposure (fuzzing protocols, IEC 62443 verification).• Field commissioning experience on BESS / microgrid / utility-scale projects.
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
