BESS Lead Engineer, Power Generation

We exist to make humanity more free. For most of human history you farmed or you starved. Technology gave people more time for the things they wanted to do instead of things they had to do. Powerful AI will be the biggest lever for human choice weve ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who dont share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.

Were singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else rethinking every layer of the stack. We acquire power design and build data centers and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI.

We hire people who care deeply about this problem space. If that is you please apply!

• Be a barrel. Full autonomy. Own things end to end take on scope without being asked no permission required to operate outside your core role.

• Insane urgency. We drive everything forward as fast as possible.

• Reason from first principles. Challenge every assumption. Zero analogy thinking no egos the best idea wins.

• Love of the game. The frontier of AI is the most interesting problem of our time. We put in long hours at high intensity to push the frontier forward.

• Build something that actually matters. If youre going to spend your time spend it on something that matters to the world.

Examples of key problems the team is working on

• Put solar storage and gas in the ground at an install rate no one in the construction market has hit. We are building generation across multiple gigawatt sites at once on a schedule traditional EPC delivery cannot meet.

• Secure supply at a scale and timeline the supply chain cannot meet and reshore it ourselves. Cells containers transformers and turbines are all constrained so we qualify new suppliers and stand up domestic capacity instead of waiting in line.

• Make solar gas and storage combine into power steady enough to run AI workloads. A training run does not tolerate a dip so the hybrid plant has to behave like firm generation even when the resource behind it does not.

• Clear balancing authority certification firm load rights permits and interconnection against long clocks and a shifting policy environment. These approvals sit on the critical path to every gigawatt so we work them years ahead of the build.
  

• Own the electrical design and sizing of multi-hundred-megawatt storage plants from single line protection and grounding through power and energy ratings and augmentation strategy across several concurrent gigawatt sites.

• Qualify and dual-source BESS vendors on technical merit running factory witness testing failure mode review and warranty terms alongside supply chain.

• Define how storage solar and on-site generation dispatch together so the plant holds a firm load profile through resource swings and generator trips.

• Drive NFPA 855 compliance hazard mitigation analysis and large-scale fire test evidence through the AHJ and the insurer before equipment reaches site.

• Take each plant through commissioning capacity and round-trip performance testing and controls integration before the first training load connects.

The below is a starting point. We always make space for exceptional people so if you dont fit this role exactly tell us where you would.

• Youve taken grid-scale battery storage from single line to energized plant and you can name the sites and the megawatts.

• Youve sized a storage system against a real duty cycle and lived with the result including the augmentation call and the places the model turned out to be wrong.

• Youve chosen between BESS vendors on technical grounds sat through factory witness testing and pushed back on a datasheet that did not survive scrutiny.

• Youve argued NFPA 855 and hazard mitigation analysis in front of an AHJ or an insurer and got to approval.

• Youve integrated storage controls with generation and load so the combined plant behaves as one machine rather than three.

• You write clearly enough that a procurement lead a fire marshal and a CEO each get the decision they need out of the same document.

• Bonus: Hybrid plant and dispatch modelling (PLEXOS PVsyst HOMER). Power system studies (PSCAD ETAP protection coordination arc flash). Behind-the-meter and islanded microgrid operation. Interconnection and market processes (FERC ERCOT MISO). Professional Engineer license.

We are committed to pay equity and transparency.
