Atwell is growing our Power & Energy team, and we are looking for a Senior Electrical Engineer to support our expanding Interconnection group. This is a strong opportunity to work on utility-scale solar, wind, BESS, substations, transmission, and other high-voltage power projects across the country.

In this role, you will support and lead a variety of interconnection and power system studies for renewable energy and grid infrastructure projects, while partnering closely with internal engineering teams and clients to deliver technically sound, high-quality solutions. This position is ideal for someone who enjoys deep technical work, client interaction, and contributing to the integration of inverter-based resources onto the grid.

What You’ll Be Doing

• Lead and support interconnection and power system studies for utility-scale renewable and high-voltage power projects

• Perform and review studies in PSSE, PSCAD, PSLF, ASPEN, PowerWorld, ETAP, SKM, CYME, EMTP, or similar tools

• Conduct a range of analyses including:

• Load flow

• Short circuit

• Dynamic analysis

• Transient studies

• Renewable model tuning

• Fault analysis

• Voltage and frequency ride-through evaluations

• Grid disturbance and system performance assessments

• Develop, review, and refine power system and renewable plant models for interconnection applications

• Support model validation, benchmarking, quality checks, and parameter tuning to align with utility, ISO/RTO, and regional performance requirements

• Evaluate and support projects across solar, wind, BESS, substations, transmission, and distribution

• Prepare and review technical deliverables including study reports, design criteria, specifications, study documentation, scopes of work, and other engineering packages

• Participate in client meetings, technical discussions, occasional site visits, and field walkdowns

• Support proposal efforts, technical approach development, and estimating for new project opportunities

• Ensure studies and engineering deliverables align with applicable codes, standards, utility requirements, and internal quality expectations

• Stay current with regulatory changes, grid codes, ISO/RTO requirements, and evolving standards related to interconnections and inverter-based resources

• Contribute to the improvement of internal workflows, tools, and methods that help streamline studies, model checks, and engineering efficiency

What We’re Looking For

• Bachelor’s Degree in Electrical Engineering from an ABET-accredited program

• Strong experience supporting interconnection studies and power systems analysis

• Experience with tools such as PSSE, PSCAD, PSLF, ASPEN, PowerWorld, ETAP, SKM, CYME, EMTP, or similar

• Experience performing dynamic studies, model development, or renewable system analysis for high-voltage or utility-scale projects

• Strong understanding of power system behavior, inverter-based resources, and grid interconnection requirements

• Familiarity with ISO/RTO processes such as…
