About American Terawatt
American Terawatt is building a new industrial electric grid for the United States. Power systems engineering is at the core of what we do.
We design and deploy advanced power transmission systems, serving large industrial loads, gigawatts at a time. Our systems deliver power to everything from frontier AI datacenters to advanced automated manufacturing, refineries, mines, and more.
We make interconnection fast, simple, and cheap. On our network, generation owners get their projects online faster, delivering abundant power at competitive prices.
The backbone of American Terawatt’s network is HVDC transmission, anchored by our unique terminal design. American Terawatt’s terminals are standardized, modular, and natively integrate energy storage. Each terminal is designed to expand to operate as a full node on our future HVDC transmission network.
About the role
We are hiring a Power Systems Engineer to help design, model, test, and deploy our HVDC terminals and transmission systems.
You will work with a Principal Engineer, the broader R&D Engineering team, and our test engineers and technicians, taking ownership of power-system modeling, subsystem validation, and commissioning support.
This is a hands-on builder role for someone who wants to solve complex power-delivery problems and help turn a new HVDC terminal design into operating infrastructure.
This is currently an individual contributor role, with the opportunity to grow into broader system-level technical ownership as the company scales. You will report directly to a Principal Engineer.
What you will own
As a Power Systems Engineer at American Terawatt, you will:
-
Contribute to the specification and design of our HVDC systems, including developing and validating terminal subsystems in both simulation and physical hardware. You will develop deep, end-to-end knowledge of the terminal design over time.
-
Use EMT and transmission-system models to evaluate how customer requirements, grid conditions, and available vendor equipment affect terminal performance. Turn the results into updated requirements, equipment specifications, and design recommendations that can be delivered on schedule.
-
Develop and execute subsystem validation tests with test engineers and technicians, including overstress and fault-injection testing against defined design limits. Compare physical results with simulations, resolve discrepancies, update models and designs, and support field commissioning to verify performance.
