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.
Bachelor's or Master's in Electrical Engineering (Power Systems preferred); 8+ years power systems planning or critical power/BESS engineering; PSSE, PSCAD, ETAP; NERC/FERC/ISO/RTO knowledge; U.S. work authorization without sponsorship.
