Senior Power System Engineer

Stellenbeschreibung:

We are seeking a Senior Power System Engineer – Renewable & Data Center Integration with extensive experience supporting utility-scale generation and large-load interconnections across the ERCOT region. The successful candidate will possess a strong background working directly with Investor-Owned Utilities, Transmission Service Providers, Independent Power Producers, renewable developers, and EPC organizations throughout the planning, design, interconnection, and execution phases of major infrastructure projects.

This role will lead transmission planning studies, interconnection assessments, dynamic and transient stability analyses, and technical due diligence efforts supporting renewable generation, energy storage, and hyperscale data center developments. Candidates should have a thorough understanding of ERCOT protocols, utility planning practices, transmission development processes, and EPC execution considerations, along with the ability to engage effectively with utility stakeholders and senior client leadership.

Key Responsibilities

Serve as a technical lead and subject matter expert for large-load and generation interconnection studies across ERCOT and other North American transmission systems.
Lead multidisciplinary engineering teams performing transmission planning, interconnection, and grid integration studies for hyperscale data centers, renewable generation facilities, battery energy storage systems (BESS), and hybrid energy projects.
Develop technical study methodologies, establish modeling assumptions, review analytical results, and provide quality assurance for complex power system studies.
Interpret and apply NERC, FERC, ERCOT, ISO/RTO, and Transmission Service Provider (TSP) requirements related to generation and large-load interconnections.
Lead the development, validation, and troubleshooting of steady-state, dynamic, and electromagnetic transient (EMT) models using ETAP, PSS®E, PSCAD, and related industry tools.
Provide technical leadership for modeling and integration of:
- Large electronic loads and hyperscale data center facilities
- Utility-scale solar, wind, and battery energy storage resources
- Hybrid generation and storage systems
- Power Plant Controllers (PPCs) and Master Plant Controllers (MPCs)
Lead technical evaluations supporting EPC design, Owner's Engineer services, and utility interconnection activities for:
- Utility-scale renewable energy projects
- Large data center developments
- High-voltage substations and collector systems
- Grid modernization and microgrid applications
Provide technical oversight for microgrid planning, design, control system integration, and resiliency assessments at both medium- and high-voltage levels.
Lead and support RTDS/RSCAD Control Hardware-in-the-Loop (CHIL) testing, model validation, and controller performance verification activities.
Serve as the primary technical interface with Investor-Owned Utilities (IOUs), Transmission Service Providers (TSPs), ISO/RTO organizations, developers, EPC firms, OEMs, and regulatory stakeholders.
Present technical findings, defend study methodologies, and communicate project risks and recommendations to utility clients, project developers, and executive leadership teams.
Perform and oversee advanced power system analyses including:
- Power flow and voltage stability studies
- Short-circuit and fault-duty analysis
- Protection coordination and relay settings review
- Arc-flash assessments
- Reactive power planning and voltage control analysis
- Harmonic and power quality studies
- System loss and operational performance assessments
Lead electromagnetic transient (EMT) studies in PSCAD, including:
- Transient overvoltage (TOV) analysis
- Transient recovery voltage (TRV) analysis
- Insulation coordination studies
- Sub-synchronous resonance (SSR) and sub-synchronous oscillation (SSO) assessments
- Inverter-based resource (IBR) interaction and control stability evaluations
Support project development activities through interconnection strategy development, technical due diligence, risk assessments, and identification of grid-related project constraints.
Mentor and develop junior engineers, provide technical guidance across project teams, and contribute to the growth of organizational technical capabilities.
Support proposal development, technical pursuits, client relationship management, and strategic business growth initiatives within the utility, renewable energy, and data center sectors.
