PCS Lead Engineer, Power Generation

The role

The PCS Lead Engineer will own the power conversion layer, including PCS and inverter topology, DC architecture, and filtering. You will write specifications, qualify platforms, set converter-level control requirements, and lead field commissioning. You will also perform root-cause analysis on fleet issues to update standard designs.

What you will do

• Own the power conversion layer including PCS and inverter topology, DC architecture, filtering and the conversion interface to MV collection.
• Write the spec and hold OEMs to it.
• Qualify platforms on measured behavior.
• Set converter-level control requirements for firm load, grid-forming and grid-following operation, ride-through, step-load response and reactive capability.
• Lead conversion-side commissioning in the field.
• Take plants through energization, first charge and discharge, islanding and transfer tests, and step-load testing.
• Root-cause fleet issues into the standard.
• Trace converter trips, derates and firmware regressions to their cause.

Required qualifications

• 10+ years of experience in power conversion for grid-scale storage or solar, including PCS and inverter specification, vendor qualification, and field commissioning.
• Experience taking power conversion from specification to energized and dispatching on grid-scale storage or solar.
• Experience writing an inverter or PCS specification that a vendor bid against and holding that vendor to it.
• Experience debugging converter behavior in the field from scope traces, power quality captures and event records.
• Experience specifying or validating grid-forming operation on a plant that has to survive islanded.
• Experience carrying a failure from a field symptom to a change in the standard design.
• Ability to write clearly for OEM engineers, commissioning agents and CEOs.
• Comfortable with regular travel of 25% or more.

Nice to have

• Grid-forming control and EMT validation.
• Converter design at the hardware level, including magnetics, thermal and device selection.
• BESS and inverter certification (UL 1741 SA and SB, IEEE 1547, UL 9540A).
• Behind-the-meter and islanded microgrid operation.
• Professional Engineer licence.
