Senior Power Systems Engineer: Grid-Forming & Storage

Energy Jobline ATTB; Théméricourt; On-site; EUR 80,000 - 120,000; Full time

Job summary

Fluidstack in France is seeking a technically hands-on engineer to own the power conversion layer across storage and solar projects, writing PCS and inverter specifications and driving field testing.

You will diagnose converter behavior, enable grid-forming operation, and coordinate with OEMs to ensure performance from first charge through dispatch, islanding, and recovery. We value clear documentation and practical engineering judgment.

Qualifications

• You've taken power conversion from specification to energized and dispatching on grid-scale storage or solar.
• You've written an inverter or PCS specification that a vendor bid against, then held that vendor to it in practice.
• You've debugged converter behavior in the field from scope traces, power quality captures and event records.
• You've specified or validated grid-forming operation on a plant that must island survive, and know where datasheets stop matching hardware.
• You write clearly so OEM engineers, commissioning agents and executives derive the needed decisions from the document.

Responsibilities

• Own the power conversion layer across storage and solar, PCS and inverter topology, DC architecture, and interfaces.
• Write PCS and inverter specifications, qualify platforms by measured behavior, and enforce vendor conformance.
• Lead conversion‑side energization, commissioning, islanding and step-load testing against real AI load profiles.
• Root‑cause converter trips, derates and firmware regressions, folding fixes back into the standard design.
