JOB DESCRIPTION We are looking for a Principal Power Systems Engineer with hands-on interconnection study experience and a passion for improving the grid integration process through AI and automation. In this role, you will lead in-depth technical analyses, build out our dynamics and short-circuit duty study capability, analyze results, and present study findings directly to utilities and customers. You will serve as a technical subject-matter expert for the engineering team, and help lead the plan that connects planning-side capacity assessment to how utilities implement it in operations. You will work with utilities, developers, and regulators to accelerate interconnection timelines. This is a unique opportunity to combine deep power systems expertise and stakeholder engagement, with cutting-edge AI solutions to modernize how studies are performed. RESPONSIBILITIES * Perform and lead load and generation interconnection studies, including steady-state, short-circuit, or dynamic analysis with widely accepted commercial tools. * Build out GridCARE's approach to dynamics and short-circuit duty studies — defining the methodology and selecting cost-effective tooling so we can run these studies when they are required. * Develop power flow and stability models to evaluate system impact for new interconnections, including data centers and renewable generation (inverter-based resources). * Serve as a technical subject-matter expert for the engineering team, advising on study methodology and interconnection process questions. * Help lead the plan that bridges planning and operations — translating capacity assessment and qualification into an approach utilities can actually implement in the operations plane. * Collaborate directly with utilities, developers, and regulators to understand their needs and facilitate smooth interconnection processes and compliance with standards. * Present study results, recommendations, and process findings directly to utility planners, project managers, and customer stakeholders. * Evaluate interconnection options, system upgrades, and Grid-Enhancing Technologies (GETs), providing clear recommendations to stakeholders. * Partner with AI and automation teams to streamline study processes and improve accuracy. * Stay engaged with the latest interconnection news, standards, and emerging solutions in power systems, including the DOE i2X forum and ESIG modeling task force. QUALIFICATIONS Required * Bachelor's degree in Electrical Engineering (Power Systems focus) or a related field. Master's or PhD preferred. * 10+ years of experience in power system studies, transmission planning, or interconnection, at a utility or a consulting firm. * Demonstrated hands-on experience running interconnection studies specifically — a minimum of two years. * Proficiency with commercial power system tools (e.g., PSSE, PSLF, PowerWorld, PSCAD, PowerGEM TARA, ASPEN). * Strong coding skills in Python or equivalent, including use of power system tool APIs (psspy, simauto, pypowergem). * Strong understanding of FERC, NERC, and ISO/RTO interconnection processes. * Experience working with or for a utility transmission planning or interconnection team. * Knowledge of steady-state and dynamic load modeling requirements. * A creative, forward-looking approach to problem solving — someone who finds paths forward rather than stopping at the bottlenecks in current planning practice — with a bias toward action. * Excellent problem-solving, communication, and collaboration skills in a fast-paced startup environment, with a focus on client interaction. Preferred * Interconnection process experience across multiple regions, particularly ERCOT/Texas, the Midwest, or the Southeast. * Working proficiency in Python or equivalent, including use of power system tool APIs (psspy, simauto, pypowergem). * Experience in applying machine-learning and AI applications to power system studies. * Able to leverage AI code development tools such as Cursor, Copilot and Claude Code to accelerate development. * Experience deploying power system applications in the cloud. * Familiarity with version control (git) and basic software engineering practices. * Ability to write well-documented, tested, and maintainable code. WHAT WE OFFER * Competitive salary and equity. * Comprehensive benefits package. * Hybrid work environment with catered lunches and snacks. * The chance to work at the intersection of AI, automation, and power systems alongside experienced engineers and leading researchers. * A mission-driven team focused on shaping the future of the energy transition. Location * Redwood City preferred, open to remote SALARY RANGE $250,000-$350,000 Total Join us in tackling one of the most important infrastructure challenges of our time — enabling the energy foundation for the age of AI.
