Exowatt · Miami
Mechanical & AerospaceEngineeringOn-siteFull-time
Exowatt is revolutionizing the energy landscape for the AI era with our groundbreaking P3 system that captures solar energy, stores it as heat, and generates electricity on demand. Founded in 2023 and backed by leading investors including Andreessen Horowitz, Sam Altman, and Felicis, we're committed to providing clean, modular, and scalable power that meets the rapidly growing demands of AI infrastructure. Our mission is to make sustainable renewable energy always available and almost free, enabling technological advancement while protecting our planet.
We are looking for a technically curious Power Systems Electrical Engineer to join our systems study team. You will be responsible for developing, maintaining, and analyzing complex power system models, as well as designing and executing test and validation strategies for advanced power conversion systems. Whether you are a seasoned expert or a recent graduate with a strong academic foundation in power electronics and transients, you will play a key role in simulating the "invisible" dynamics of the modern electrical grid and validating real-world hardware behavior against those models.
This position is based in Miami, FL preferred, however an alternate location of Austin, TX is possible for the right candidate. If hired for this role, relocation to one of these sites is required. We provide relocation assistance.Simulation & Modeling
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 (IBRs) such as generators, solar, and Battery Energy Storage Systems (BESS)
Conduct Sub-Synchronous Oscillation (SSO) studies, Control Interaction (CI) analysis, and Transient Overvoltage (TOV) assessments
Develop and maintain simulation environments for power electronics, energy storage, power conversion, and grid-interactive systems
Test & Validation
Create and execute test plans, test procedures, and validation protocols for electrical and power system components and integrated systems
Perform model-in-the-loop (MIL), software-in-the-loop (SIL), hardware-in-the-loop (HIL), and lab-based power converter testing as appropriate
Validate simulation results against experimental and field data; 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; drive corrective actions with cross-functional teams
Design and automate test infrastructure, data collection workflows, and post-processing and analysis tools
Cross-Functional Contribution
Support controls and firmware teams by evaluating system response, protections, edge cases, and failure modes
Translate complex simulation and test data into clear, actionable technical reports for clients, utilities, or internal stakeholders
Contribute to design reviews, risk assessments, and engineering decision-making throughout product development
