Sr. Electrical Engineer - Power Systems

Arbor Energy•El Segundo, CA

About The Position

Arbor Energy & Resources Corporation is seeking a Senior Electrical Engineer – Power Systems to own the electrical architecture of its supercritical CO₂ power plants. The role spans conceptual single-line design, generator selection, synchronization and protection, utility interconnection, procurement, installation, commissioning, and first synchronization to the grid. The plants will use multi-unit turbine-generators in the 10–50 MW range, in both transmission-level grid-tied and islanded behind-the-meter configurations. As Arbor's first electrical engineer, this is a hands-on position responsible for designing, specifying, procuring, and commissioning electrical equipment. The engineer will work closely with turbomachinery, controls, process, and test engineers in a fast-paced, first-of-a-kind hardware environment, and may define and review third-party engineering work when additional capacity is needed. Arbor Energy develops modular, fuel-flexible power systems intended to provide clean, reliable baseload electricity with zero operating emissions. Its technology centers on a supercritical CO₂ turbine with integrated carbon capture.

Requirements

Bachelor's degree in Electrical Engineering or a related engineering field.
At least 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 power-system studies such as load flow, short circuit, arc flash, motor starting, and 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.

Nice To Haves

Experience with islanded power systems, load shedding, and generator paralleling in oil and 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 experience with RTO/ISO or CAISO/WECC processes.
Advanced degree (M.S.) in Electrical Engineering with a power systems emphasis.
Background in startup environments or first-of-a-kind hardware development.

Responsibilities

Own power system architecture for multi-unit grid-tied plants and islanded microgrids, including 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 protection philosophy and coordination strategy for generators, transformers, medium-voltage switchgear, and large motors; 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 using ETAP, PSCAD, PSS®E, or equivalent tools.
Specify and procure major electrical equipment, including generators, step-up transformers, switchgear, medium-voltage motors and VFDs, MCCs, and UPS; 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.
Lead electrical commissioning through first fire, full-speed no-load, and synchronization.
