Power Systems Electrical Engineer - EMT Modeling/Simulation & Test Validation
About the job
- Proficiency or academic experience in PSCAD/PSSE and/or MATLAB/Simulink, and PLECS.
- Preferred exposure to LabVIEW, RTDS, and LTspice.
- Familiarity with oscilloscopes, power analyzers, data acquisition systems, microcontrollers, programmable logic controllers, and programmable power supplies or load banks.
- Deep understanding of power-system transients, control theory, and power electronics.
- Proficiency in Python or MATLAB for post-processing simulation and test data.
- Familiarity with IEEE 1547, NERC PRC/MOD, FERC requirements, or relevant IEC/UL standards, including academic-level familiarity.
- B.S., M.S., or Ph.D. in Electrical Engineering with a focus on Power Systems, Power Electronics, or Controls.
- Three or more years of experience is preferred; recent university graduates may qualify with significant project work or a thesis involving EMT simulation, hardware testing, or power converter validation.
- Strong mathematical aptitude in differential equations, phasor analysis, and system dynamics.
- Experience designing and executing laboratory tests for electrical systems and interpreting measured data.
- Ability to debug complex multidisciplinary systems and communicate findings to technical and non-technical audiences.
- For recent graduates: a capstone project or internship focused on power-system modeling, comfort with Python or MATLAB for simulation-data post-processing, and experience investigating how underlying model code affects the grid.
- Build and execute system-level power-system simulations using PSCAD/EMTDC or MATLAB/Simulink to analyze transient, steady-state, and dynamic phenomena.
- Perform impact studies for inverter-based resources, including generators, solar, and battery energy storage systems.
- Conduct sub-synchronous oscillation studies, control-interaction analysis, and transient-overvoltage assessments.
- Develop and maintain simulation environments for power electronics, energy storage, power conversion, and grid-interactive systems.
- Create and execute test plans, test procedures, and validation protocols for electrical and power-system components and integrated systems.
- Perform model-in-the-loop, software-in-the-loop, hardware-in-the-loop, and lab-based power-converter testing as appropriate.
- Validate simulation results against experimental and field data, and improve model fidelity over time.
- Analyze transient, fault, thermal, and dynamic behavior of power systems under normal and off-nominal conditions.
- Investigate root causes of test failures and performance gaps, and drive corrective actions with cross-functional teams.
- Design and automate test infrastructure, data-collection workflows, and post-processing and analysis tools.
- Support controls and firmware teams by evaluating system response, protections, edge cases, and failure modes.
- Translate simulation and test data into actionable technical reports for clients, utilities, or internal stakeholders.
- Contribute to design reviews, risk assessments, and engineering decision-making throughout product development.
- Exposure to LabVIEW, RTDS, and LTspice.
- Three or more years of professional experience.
About the company
Exowatt designs, installs, and maintains modular full-stack renewable energy systems for commercial and industrial clients. Its products are customizable energy solutions built from modular components that can be designed to meet specific energy needs and regulatory requirements, then installed on-site and supported through ongoing maintenance. The company’s approach combines consulting, system design, installation, and long-term service into a single, integrated package, enabling a seamless transition to renewables. This end-to-end service helps clients scale energy capacity as needed and manage energy performance over time. Exowatt differentiates itself by offering a true full-stack, modular package that covers from initial assessment to ongoing upkeep, fostering long-term relationships rather than one-off projects. Its goal is to help businesses lower both their carbon footprint and energy costs by moving to renewable energy with adaptable, scalable systems.

Simplify's Take
What believers are saying
- Exowatt raised $50 million in November 2025, reaching $140 million total funding.
- The January 2026 ExoRise launch targets a 90+ GWh signed-demand backlog.
- Austin's 11-acre campus expands manufacturing capacity for AI data-center deployments.
What critics are saying
- Exowatt still lacks a commercially proven pilot before end-2026.
- Mainspring, batteries, and other firm-power options already ship; Exowatt remains development-stage.
- If P3 misses cost or reliability targets, its 90+ GWh backlog evaporates.
What makes Exowatt unique
- ExoRise bundles land, power, and data-center shells into one 2026 product.
- P3 stores solar as heat, then dispatches electricity day and night.
- Austin manufacturing and Miami engineering enable domestically assembled, containerized energy systems.
