We are building the next generation of solid‑state, grid‑interactive power blocks that enable high‑density, flexible power delivery for datacenters, renewable energy systems, and advanced microgrids

The Validation Engineer is responsible for planning, executing, and owning system‑level validation activities for Solid‑State Transformer (SST) and microgrid solutions
. This role ensures that products meet functional, performance, reliability, and grid‑interaction requirements across simulation, HIL, laboratory, and early field environments.

The Validation Engineer acts as the bridge between design intent and real‑world behavior
, working closely with simulation, HIL, controls, hardware, application, and standards teams to verify that system requirements are correctly implemented and robust under normal, abnormal, and fault conditions.

• Develop validation plans and strategies for SST and microgrid products across development stages.
• Translate system, functional, and grid‑interaction requirements into clear validation test cases and acceptance criteria.
• Define validation coverage across:
• Grid‑connected operation
• Islanded microgrid operation
• Mode transitions and recovery
• Abnormal and fault conditions
• Execute and coordinate validation activities across multiple platforms, including:
• Offline simulation (with simulation engineers)
• Laboratory and hardware‑based testing
• Ensure consistency and traceability of validation results across simulation, HIL, and hardware.

• Validate system behavior related to:
• Voltage, current, and power regulation
• Dynamic response and transient performance
• Load changes and operating envelope limits
• Verify system behavior against defined requirements and operating scenarios.

• Support validation of:
• Fault detection and protective actions
• Recovery and reconnection behavior
• Work with HIL and protection teams to validate:
• Timing, sequencing, and coordination of protective actions
• Ensure system behavior is predictable and safe under faulted and stressed conditions.

• Support validation activities aligned with US interconnection and grid expectations, including:
• IEEE 1547 /…
