Summary
AI training and inference clusters produce large, fast, synchronized power swings. A single GPU rack can move more than half of its rated load in milliseconds, and when hundreds of racks move together the effect reaches the facility boundary and the grid. We are developing a hybrid energy storage system for data centers to protect upstream infrastructure and increase usable capacity.
We are seeking a Research Intern (Hardware Implementation and Validation) to take this system from design to hardware. You will own the implementation and validation of the storage system and its controllers, compare the design's predicted behavior against what the hardware actually does, and feed the differences back into the design. Where the measurements show that the architecture, sizing, or control law needs to change, you will propose and implement the change. This is a hands-on engineering role with a research component. Results are expected to be reported internally and, where appropriate, to feed conference publications and standards discussions.
Job Responsibilities
Build, commission, and safely operate a bench-scale hybrid energy storage system (batteries, supercapacitors, bidirectional DC/DC converters, common DC bus) with programmable loads and a real-time control platform.
Implement power-split and energy management controllers on real-time hardware and evaluate candidate control strategies head-to-head under repeatable transient test profiles.
Design and execute a validation campaign: define test cases from realistic load traces, instrument the bench at the required time resolution, and measure response time, bus voltage deviation, energy split, and state-of-charge behavior.
Compare measured results against simulation models, identify where the models are incomplete (converter dynamics, sensing and communication latency, storage non idealities), and update them.
Recommend and implement design updates to storage sizing, converter control bandwidth, and the interface between fast local control loops and the supervisory controller.
Document hardware, test procedures, and findings so the work can be reproduced and extended.
Communicate results via technical reports, presentations, and contributions to publications and patents as appropriate.
A Day in the Life
Align with technical leads on build milestones, test plans, and success metrics.
