About kos.ai
Trillions of dollars are flowing into datacenters, defense, energy, and manufacturing. The finance teams processing that capital can't keep up. 800-page invoices, thousand-page contracts, landing every few weeks, often on weekends. The world can't hire specialized accountants fast enough.
Kos is the world's first virtual finance employee for america’s industrial revival. We're processing invoices for some of the fastest-growing infrastructure and defense companies in America. Backed by $12M from 8VC, XYZ, and MVP with industry-leaders as shareholders (Keith Taylor [ex-CFO Equinix], Heather Paduck [CFO STACK], Matt DeNezza [ex-CFO Crusoe], Sachin Katti [Industrial Compute OpenAI]).

The Role
You'll work alongside the founding engineering team on bounded projects. Eval infrastructure. ERP integration stubs. Internal ops dashboards. The agent training pipeline. Whatever you ship lands in production at live customers.
What you'll do:
Build and ship a bounded project in one of: eval infrastructure, ERP integration stubs, internal ops dashboards, or the agent training pipeline
Partner with the founding team. They're your reviewer and your mentor.
Learn how an AI-native product works under the hood. The agent loop, the eval harness, the production plumbing. Not the marketing version.
Contribute to code reviews, design discussions, and the culture of the team
You
Current CS or ML undergrad or Master's student with a hands-on project or internship track record
Fluent in one of Python, TypeScript, or Go. You pick up whatever else the project needs.
You've played with LLMs, agents, or computer-use workflows. You've built something, not just read about it.
You're hungry to ship code into production, not complete a rotational checklist
You'd rather ship one thing a customer touches than polish ten projects that live on a demo-day slide
You're comfortable working in-person at our SF office for the whole internship
Comp and Benefits

Team
Tanuj and Mani met at Stanford as graduate researchers under Sachin Katti.
Tanuj spent his career in and around the operators Kos serves: IT, datacenters, industrials, and hardware. He previously founded Spot AI, a computer vision company which scaled to over 1,000 enterprise customers. Mani's an International Olympiad medalist, earned his Engineering PhD at Stanford, & published leading research at Microsoft Research. He then built product within Microsoft Azure's Strategic Missions and Technologies group.
We built Kos because the finance and operations teams behind America's re-industrialization are talented, overwhelmed, and can't hire their way out. Every CFO we spoke to described the same problem: 800-page pay apps, thousand-page contracts, work piling up on weekends, and a talent pool for inventory, utilities, capex, and construction accounting that's simply too small to meet the moment. The back office of the buildout is the bottleneck, and it's the one nobody's building for. They deserve a partner that can keep pace with their ambition.
