Arbor Energy

Rocket engineering for power generation.

Arbor is a next-generation turbine company using rocket engineering to deliver clean firm power. Rocket engines generate enormous power out of very small volumes. Arbor applies that approach to power generation, using supercritical CO₂ to deliver the same power from a turbine roughly one-tenth the size of a conventional one. Turbine engineering supplies the materials and cooling a power system needs to run continuously for decades. Arbor’s power system, HALCYON, uses oxy-combustion—burning fuel in pure oxygen—to eliminate NOx, SOx, and particulate emissions. This process enables CO₂ to be captured directly from the fuel and stored permanently underground. It also produces water, so a plant can operate without drawing on local water supplies. Each HALCYON unit delivers 25 MW, and units can run independently or get combined into plants of 100 MW and more as demand grows. Components are additively manufactured on standard 3D printers, offering a path outside the legacy supply chains th

About Us

At Arbor Energy & Resources Corporation ("Arbor Energy"), we’re creating technology to power our lives while protecting the planet that sustains them.  Our advanced power systems deliver clean, reliable baseload electricity with zero operating emissions—modular, fuel-flexible, and engineered for the realities of today’s energy demand. At the core is a supercritical CO₂ turbine with integrated carbon capture, designed to bring carbon-neutral power online quickly at meaningful scale. 

Our team includes aerospace engineers, combustion experts, and systems thinkers with a shared goal: to build technology worthy of the world we want to live in. While many of us began our journeys looking to the stars, we’re applying that expertise here at home to deliver dependable, emission-free baseload power and a future of lasting abundance.  

If you share our values and are drawn to rigorous work with lasting impact, we’d love to learn more about you. Come build what the future will run on.

Steward our planet: We build for tomorrow, ensuring every bolt we tighten and every hand we lend leaves our environment stronger than we found it.

Lead with Love: We champion the success of our people, partners, and planet, nurturing excellence through camaraderie and rigor.

Explore the Uncharted: We embrace the unknown with curiosity, using courage and discipline to transform uncertainty into opportunity.

Role Overview

We're looking for a Senior Electrical Engineer – Power Systems to own the electrical architecture of Arbor's supercritical CO₂ power plants—from the first conceptual one-line through generator selection, synchronization and protection design, utility interconnection, procurement, installation, and first synchronization to the grid. As Arbor's first electrical engineer, you will set the architecture for multi-unit plants of 10–50 MW turbine-generators, both grid-tied at transmission level and in islanded behind-the-meter configurations. This is a hands-on role: you will design, specify, procure, and commission the equipment yourself, and bring in third-party engineering when the schedule demands more hands, not because the work is outside your reach. You'll partner closely with turbomachinery, controls, process, and test engineers in a fast-paced, first-of-a-kind hardware environment, building the electrical discipline that delivers carbon-neutral baseload power.

Responsibilities

  • Own the power system architecture for multi-unit grid-tied plants and islanded microgrid configurations: single-line diagrams, generator step-up and medium-voltage distribution topology, auxiliary power, and DC/UPS systems.
  • Lead generator, excitation, synchronization, and load-sharing design, including system behavior during load steps, faults, breaker operations, motor starting, and loss-of-generation events.
  • Develop the protection philosophy and coordination strategy for generators, transformers, medium-voltage switchgear, and large motors, and produce or review relay settings and time-current coordination.
  • Own utility interconnection from feasibility screening through interconnection agreement and compliance, including NERC MOD-026/027 and PRC-019/024 and IEEE 2800 requirements.
  • Perform and direct load-flow, short-circuit, arc-flash, motor-starting, and transient stability studies in ETAP, PSCAD, PSS®E, or equivalent.
  • Specify and procure major electrical equipment—generators, step-up transformers, switchgear, medium-voltage motors and VFDs, MCCs, and UPS—and manage vendor design reviews, factory acceptance tests, and installation.
  • Own or direct hazardous-area classification, grounding, and lightning protection design for facilities handling natural gas, oxygen, and high-pressure CO₂.
  • Define scope for and review third-party electrical engineering when additional capacity is needed, and lead electrical commissioning through first fire, full-speed no-load, and synchronization.

Requirements

  • Bachelor's degree in Electrical Engineering or related engineering field.
  • 8+ years of experience in power-generation, industrial, or utility electrical systems, including medium-voltage generation and distribution and transmission-level interconnection.
  • Hands-on commissioning or startup experience with a generating plant or large industrial electrical system.
  • Demonstrated ability to take electrical equipment from concept through specification, procurement, installation, and energization.
  • Working fluency in generator protection, excitation, and synchronization, and in power system studies (load flow, short circuit, arc flash, motor starting, coordination) using ETAP, SKM, PSCAD, or equivalent.
  • Knowledge of NEC, NFPA 70E, NESC, IEEE, and NERC standards applicable to generating facilities.
  • Proven ability to own technical development of complex hardware from concept through validation in fast-paced settings.

Preferred Qualifications

  • Experience with islanded power systems, load shedding, and generator paralleling in oil & gas, LNG, industrial-gas, or microgrid applications.
  • Gas-turbine or reciprocating-engine generator package experience, including static excitation, generator protection panels, and neutral grounding.
  • Utility interconnection studies and RTO/ISO or CAISO/WECC process experience.
  • Advanced degree (M.S.) in Electrical Engineering with a power systems emphasis.
  • Background in startup environments or first-of-a-kind hardware development.

Benefits & Compensation

  • Pre-IPO stock options
  • Medical, dental, and vision insurance (Arbor covers 90% for employees)
  • Basic life insurance fully covered
  • Health savings account (HSA) with matching
  • Flexible savings account (FSA)
  • Unlimited PTO  
  • 12+ company holidays, including Earth Day!  
  • 401(k)
  • Commuter benefits
  • Annual learning and development stipend
  • And more!

Base Pay: $165,000 - $185,000 USD/year. The salary is subject to the applicant's skills, qualifications, experience, and geographic location.

Our Commitment

Arbor Energy is proud to be an equal opportunity employer. We evaluate qualified applicants without regard to race, religion, national origin, gender identity or expression, sexual orientation, age, marital or veteran status, disability, or any other protected characteristic under applicable law. Solving global energy challenges requires a wide range of perspectives and experiences, and we are committed to building a team that reflects the world we serve.

Our hiring process is designed to be accessible, fair, and focused on the work that matters most for this role. Reasonable accommodations are available throughout the hiring process and employment—please let us know if you need one.
