ON.energy is building the power infrastructure that makes the AI era possible.
As AI demand surges past what the grid and traditional data centers can support, ON.energy provides a new class of power technology proven at gigawatt scale and trusted by the world's leading cloud and AI companies.
Our systems are already deployed across 2.5 GW of hyper-scale campuses, validated by top U.S.
national labs, and certified for grid-safe operation by major utilities.
With real products in the field, we're scaling faster than the grid can, transforming power from a bottleneck into a competitive advantage for the companies building the future.
Location - Hybrid in Houston, TX / Reston, VA / Toronto, CA Role Overview The Chief Electrical Engineer serves as a senior technical advisor and Subject Matter Expert (SME) for ON.Energy's electrical and power systems.
This role provides high-level engineering support for critical field issues and serves as a key technical consultant during the product design phase and when modifications are required.
You will act as a bridge between design theory and real-world operational performance, ensuring electrical safety, system reliability, and grid compliance through data-driven analysis and expert review.
Key Responsibilities High-Level Technical Support & Escalation * Field Technical Support: Serve as the senior technical point of contact for complex or unresolved electrical issues at project sites, from equipment through the decommissioning phase.
* Root Cause Analysis: Provide expert oversight and direction for electrical failure investigations (e.g., arc flash incidents, harmonic issues, or protection trips), ensuring modifications are technically sound and address the core issue.
* SME Consultation: Act as a "Level 2" support resource for sales engineering, providing technical validation for non-standard site requirements, utility interconnection requests, or client-specific electrical configurations.
Design Advisory & Gate Reviews * Technical Reviews: Participate as a Subject Matter Expert in Design Reviews and Stage-Gate Reviews, identifying potential electrical risks, protection gaps, or efficiency losses before they reach the field.
* Product Modification: Provide technical guidance on hardware updates, firmware-hardware compatibility, or component substitutions based on field performance data and evolving safety standards (UL, NFPA, IEEE). * Requirement Support: Assist the product team in defining electrical requirements for new hardware, ensuring they are grounded in realistic engineering constraints and grid-code requirements.
Simulation, Validation & Grid Compliance * Advanced Analysis: Perform or oversee electrical simulations, including Power Studies (Short Circuit, Coordination, Arc Flash). * Electrical Resilience: Ensure all electrical designs and site-specific deployments are validated against extreme site conditions and utility requirements, including: * Power Quality: Validating harmonic profiles and voltage stability at the Point of Interconnection (POI). * Protection & Control: Overseeing the logic and reliability of the protection scheme, Battery Management System (BMS), Power Conversion System, (PCS) and Energy Management System (EMS). * Environmental Resilience: Ensuring electrical enclosures and insulation systems are rated for high-altitude, high-humidity, or coastal environments.
Required Qualifications * 20+ years of electrical engineering experience, specifically within Battery Energy Storage (BESS), Medium/High Voltage systems, Medium Voltage UPS, Power Conversion Systems (PCS), or Utility-Scale Power Generation.
* Expertise in Power Studies: Hands-on experience or deep knowledge of simulation tools (e.g., ETAP, SKM, or PSS/E) to solve complex protection and coordination challenges.
* Strategic Problem Solver: Proven ability to diagnose complex electrical failures in the field (e.g., ground faults, inverter synchronization issues) and translate them into actionable design improvements.
* Communication: Ability to communicate technical risks and complex electrical concepts clearly to both internal stakeholders and external utility partners.
