Chief Electrical Engineer

Houston, Texas, United States; Reston, Virginia, United States

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.

 

Chief Electrical Engineer

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

  1. 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.
  1. 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.
  1. 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.

 

For US-based roles - What you’ll get:

  • Competitive salary + annual performance-based bonus eligibility
  • Medical, dental, and vision insurance
  • 401(k) with company match
  • Paid time off and company holidays 

For Mexico-based roles - What you’ll get:

  • Competitive salary + annual performance bonus eligibility
  • Christmas Bonus (Aguinaldo): 30 days
  • Major medical expenses and life insurance
  • Paid time off and holidays (per local policy)

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
