Role OverviewWe'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.
