About the Job

Requirements

  • A bachelor's degree with at least 7 years, a master's degree with at least 5 years, or a PhD with at least 4 years of relevant experience, including substantial hands-on experience developing, executing, troubleshooting, and validating PSCAD/EMTDC models and studies.
  • Strong background in power-system analysis, including generation, transmission, grid integration, and utility interconnection requirements.
  • Demonstrated experience developing and executing electromagnetic transient studies using PSCAD/EMTDC or a comparable EMTP platform.
  • Experience performing steady-state and RMS dynamic simulations using PowerWorld, PSS®E, DIgSILENT PowerFactory, ETAP, or an equivalent power-system analysis tool.
  • Experience using Python to automate simulations, parameter sweeps, sensitivity analyses, results processing, and repeatable study workflows.
  • Strong understanding of power-system stability, including transient, voltage, frequency, and control-system performance.
  • Strong understanding of synchronous generators, gas turbines, gas engines, excitation systems, governors, plant controllers, transformers, and protection systems.
  • Experience developing fit-for-purpose dynamic models and integrating, testing, troubleshooting, and validating OEM-provided models.
  • Experience performing grid-performance and compliance studies, including LVRT, HVRT, frequency ride-through, frequency response, reactive-power capability, voltage regulation, fault response, and transient stability.
  • Ability to independently develop models, define and execute study cases, assess the technical validity of results, and communicate findings to internal engineering teams, utilities, consultants, and equipment suppliers.

Responsibilities

  • Develop and maintain in-house power-system models for hyperscale data-center power systems, including onsite generation, utility interconnections, microgrids, and hybrid energy systems.
  • Lead EMT modeling and transient studies using PSCAD/EMT tools to evaluate dynamic performance of data-center generation systems, including gas engines, gas turbines, BESS, fuel cells, UPS systems, and hybrid power architectures.
  • Perform power-system studies using PSCAD, PowerWorld, TARA, PSS®E, PowerFactory, ETAP, or similar tools to validate system performance and compliance with utility and ISO requirements.
  • Use PSCAD Automation Library or equivalent scripting and Python-based batch simulation.
  • Develop fit-for-purpose system-level and generic models; integrate, test, troubleshoot, and validate detailed OEM models; and develop simplified screening models where appropriate.
  • Perform grid-compliance studies for ERCOT, PJM, MISO, WECC, SPP, and other utility/ISO requirements, including load smoothing, LVRT, HVRT, frequency ride-through, reactive-power capability, voltage regulation, frequency response, load-ramp-rate limitations, and large load-step response.
  • Analyze the interaction between hyperscale data-center loads and the electrical grid, including AI workload fluctuations, large load ramps, transient events, and generation-response requirements.
  • Develop and execute dynamic simulation cases to evaluate generator transient response, voltage and frequency stability, load acceptance, load rejection, black-start capability, islanded operation, microgrid operation, and grid-connected scenarios.
  • Support optimization of onsite generation systems by evaluating generator sizing, controls, redundancy strategies, energy-storage integration, and overall system performance.
  • Perform utility interconnection studies and support technical discussions with utilities, ISOs, consultants, and equipment suppliers.
  • Conduct screening-level transmission transfer-capability and deliverability assessments using PowerWorld or PSSE, including contingency analysis, injection and withdrawal sensitivities, interface-flow analysis, voltage assessment, and identification of transfer-limiting elements.
  • Review and validate vendor models and simulation results for generators, turbines, BESS, UPS systems, protection systems, and plant controllers.
  • Support commissioning and field-validation activities by comparing simulation results with actual plant performance and tuning models as required.
  • Develop technical reports, study documentation, and compliance packages demonstrating that power systems meet utility, ISO, and customer reliability requirements.
  • Support innovation and pilot projects at the SBE innovation center, including development of power-system models, validation of simulation results, and testing of advanced power solutions for hyperscale data centers.
  • Support testing and evaluation of BESS, MV/LV UPS, and hybrid energy-storage solutions through simulation and field validation, including dynamic response, load smoothing, power-quality improvement, and microgrid/islanded-operation performance.

Desired Qualifications

  • Experience with North American utility and ISO/RTO interconnection requirements, including ERCOT, WECC, SPP, PJM, MISO, CAISO, AEP, or similar organizations.
  • Experience supporting utility interconnection applications, model submissions, grid-compliance testing, commissioning, or field validation.
  • Experience modeling hyperscale data-center electrical systems, AI workload fluctuations, large load ramps, UPS systems, and mission-critical power architectures.
  • Experience modeling large-scale onsite generation facilities, including gas engines, gas turbines, fuel cells, BESS, or hybrid generation systems.
  • PSCAD model-development experience involving inverter-based resources, BESS, STATCOMs, UPS systems, microgrids, and plant-level controls.
  • Experience analyzing islanded operation, black start, load acceptance and rejection, microgrid operation, renewable integration, and N+1 or N+N reliability configurations.
  • Knowledge of protection coordination, short-circuit analysis, generator protection, SCADA, communications, and plant control systems.
  • Familiarity with applicable IEEE, NERC, FERC, ISO/RTO, and utility-specific technical requirements.
  • Experience using version control, model libraries, standardized simulation test benches, and automated technical-reporting workflows.
  • Professional Engineer license preferred.

About the Company

SB Energy

Builds and runs power plants and AI data centers

SB Energy develops, builds, owns and operates large data center campuses and the power plants that supply them, mainly for AI companies across the United States. Its approach puts power first, developing on-site generation and grid connections alongside its campuses so computing capacity can come online faster. The company also owns solar and battery storage projects, including a Texas solar complex whose anchor customer is Google. It earns revenue by leasing data center capacity to tenants under long-term agreements and by selling electricity from its power portfolio. SB Energy, a SoftBank Group company, was founded in 2019 and is headquartered in Redwood City, California.
