Senior Power Systems Engineer

About Redtree Redtree Engineering specializes in engineering, project management, and construction support services across mission-critical facilities, power systems, industrial projects, and complex infrastructure. Redtree offers 100% remote work for this role. As a growing engineering firm, we've built our team around flexibility from day one, giving engineers the ability to do serious, high-impact power generation design work from anywhere in the U.S., without relocating or commuting

Position Summary Redtree is seeking a Senior Power Systems Engineer with deep expertise in large load and renewable interconnections, dynamic modeling, and critical power system design to support transmission-level planning, system impact studies, and EPC design efforts for utility-scale renewable projects, battery energy storage systems (BESS), and hyperscale data center developments. The ideal candidate combines strong analytical and modeling capability with hands-on experience delivering power systems and controls solutions for mission-critical infrastructure, and brings a practical understanding of ISO/RTO planning, operational, and regulatory requirements (ERCOT experience is a strong plus).

This is an exciting opportunity to join a growing engineering team that partners with industry-leading clients to deliver innovative, resilient, and scalable solutions from concept through construction and commissioning, all while working 100% remote.

Key Responsibilities

• Lead and support large load and generation interconnection studies, including for ERCOT and other transmission systems.
• Apply and interpret NERC, FERC, ISO/RTO, and TSP requirements for both generation and large load interconnections.
• Develop and validate steady-state models in ETAP and PSSE, and dynamic models in PSSE and PSCAD for large electronic loads (including data centers) and PV, wind, and BESS resources.
• Support development and integration of Solar/Wind/BESS Power Plant Controllers (PPCs) and Master Plant Controllers (MPCs).
• Participate in EPC HV/MV substation design studies for large data center projects and utility-scale PV, wind, and BESS projects.
• Support or lead microgrid design and control studies at MV and HV levels, drawing on critical power and MV-UPS system experience.
• Support RTDS / RSCAD Control Hardware-in-the-Loop (CHIL) testing.
• Interface with Transmission Service Providers (TSPs), ISO/RTOs, developers, OEMs, and project stakeholders.
• Perform steady-state and short-circuit analyses, including load flow studies, short-circuit analysis, protection coordination, arc-flash studies, reactive power and energy loss analysis, and harmonic studies.
• Conduct electromagnetic transient (EMT) studies in PSCAD, including transient overvoltage (TOV), transient recovery voltage (TRV), insulation coordination, and SSR/SSO screening and mitigation analysis.
• Bring BESS, power conversion system (PCS), and controls/EMS integration expertise to support battery storage and hybrid energy projects.

If you....

• Hold a Bachelor's or Master's degree in Electrical Engineering, with a focus on Power Systems preferred.
• Have 8+ years of relevant experience in power systems planning, interconnection studies, or critical power/BESS engineering.
• Have strong experience with PSSE dynamic modeling and analysis, PSCAD EMT modeling, and ETAP steady-state and protection studies.
• Have demonstrated experience with large load interconnection studies, with data center experience strongly preferred.
• Have experience with generation interconnection (PV, wind, BESS) and ERCOT or other ISO/RTO transmission planning and compliance requirements.
• Have experience developing dynamic PSSE and PSCAD models for large inverter-based resources and electronic loads.
• Familiar with NERC, FERC, ISO/RTO, and TSP requirements for both generation and large load interconnections.
• Have experience embedding and coordinating PPC and MPC control strategies, and with RTDS / RSCAD CHIL testing.
• Bring hands-on experience with BESS, power conversion systems, or MV-UPS/critical power systems for data center applications.

Preferred Qualifications

• Professional Engineer (PE) license.
• Experience with real-time simulation (HIL/SIL/PIL) and DSP/FPGA-based control system design.
• Proficiency in MATLAB/Simulink and Python for power systems modeling and validation.
• Prior experience leading or building high-performing engineering teams.
• Experience across multiple ISO/RTO markets in addition to ERCOT.
• Background in grid-forming technologies and hybrid energy solutions.

What Redtree Offers

• 100% remote work, U.S.-based, with no relocation or office requirement.
• 100% employer-sponsored benefits.
• Direct exposure to the full project lifecycle, from concept through construction and commissioning, rather than a narrow phase or discipline silo.
• A growing, entrepreneurial engineering team partnering with industry-leading clients on mission-critical facilities, power systems, and complex infrastructure.
• Multiple openings across Mid to Senior levels, with the flexibility to match title and compensation to the selected candidate's experience.

Work Authorization: Must be able to work in the United States without employer sponsorship, now or in the future.
