## Description

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 Application Engineer is responsible for defining, adapting, and supporting Solid-State Transformer (SST) and microgrid solutions for data center applications with integrated distributed energy resources and storage.

This role serves as the technical bridge between customers, utilities, and internal product teams, translating aggressive AI/ML load requirements and DER capabilities into reliable, scalable, and utility-compliant system solutions., Application Definition & System Architecture

 * Work with customers and internal teams to define SST and microgrid system architectures for AI/ML data centers.
 * Translate data center load profiles into electrical system requirements.
 * Support architectures involving:
 * Utility-connected SSTs (LV/MV)
 * Behind-the-meter and hybrid microgrids
 * Grid-interactive and islanded operation
 * Evaluate technical tradeoffs related to efficiency, redundancy (N, N+1, 2N), fault tolerance, and scalability.

Customer & Utility Technical Engagement

 * Act as the primary technical interface with Hyperscalers, colocation providers, EPCs, and utilities.
 * Support customer discussions on:
 * Power delivery architectures (AC vs. DC, MV distribution)
 * Load step response and AI/ML workload dynamics
 * Power quality, reliability, and resilience
 * Support utility-facing discussions on interconnection, protection, and operational impacts.

Standards, Interconnection & Compliance Support

 * Partner with standards and certification teams to ensure application designs are certifiable and utility-acceptable.

Technical Proposal & Pre-Sales Support

 * Develop technical proposals, system block diagrams, single-line diagrams, and performance analyses.
 * Support RFP and RFQ responses, including:
 * System sizing and configuration
 * Operating modes and use cases
 * Grid support and resiliency capabilities
 * Support cost-performance trade studies and solution comparisons.

Internal Engineering Collaboration

 * Provide clear application-level requirements to:
 * Power electronics design
 * Control and software teams
 * Mechanical and thermal engineering
 * Validate solutions against real-world data center operating conditions.
 * Provide feedback from customers and the field into product roadmap discussions.
