## Job description

ABOUT KOS.AI http://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]).

Media: The Information covering our launch https://www.theinformation.com/newsletters/ai-infrastructure/startup-trying-tame-accounting-chaos-behind-ai-data-centers?rc=yzqusk

## 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

- Relocation benefits
- Visa sponsorship for eligible candidates

## 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.

## About kos.ai

## Company Overview
- **One-liner**: Kos develops the world’s first virtual finance employee, an AI agent that automates complex financial workflows (pay applications, purchase orders, invoicing, and reconciliation) for capital-intensive infrastructure companies.
- **Entity Type**: Private (inception financing)
- **Headquarters**: San Francisco, California, USA
- **Founded**: 2025
- **Founders**: Tanuj Thapliyal (CEO) and Mani (co-founder; International Olympiad medalist, Stanford Engineering PhD, former Microsoft Research)

## Core Business
- **Primary industry**: AI-powered finance automation for digital infrastructure, defense, energy, and industrial sectors.
- **Target customers**: B2B — enterprise finance and operations teams at Capex-heavy companies (data center operators, defense contractors, energy firms, long-lead equipment manufacturers, construction contractors).
- **Mission**: To automate the back-office bottleneck of America’s re-industrialization, enabling CFOs to scale financial operations without hiring their way out of the talent shortage.

## Products & Services
- **Kos (Virtual Finance Employee)**: A fully autonomous AI agent that is given its own workstation, identity, and software licenses. It handles:
  - **Pay Applications**: Reviews and reconciles vendor invoices line-by-line against GMP contracts; catches missing backup, overbills, and calculation errors.
  - **Purchase Orders**: Generates, routes, and closes out POs by navigating the ERP like a skilled human.
  - **Custom Workflows**: Learns any new process (e.g., utilities billing, draw requests, month-end close) over a screenshare, then runs it within audit-grade rails.
  - **Communication**: Works via email, Teams, Slack, phone, Zoom, or Meet — no UI to learn.
- **Same-Day Pay Application Reviews**: Announced GA in June 2026, enabling data center operators to process pay applications in hours instead of days.

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed.
- **Key Metric**: $12M inception financing (led by 8VC and XYZ Ventures, late 2025). No further funding rounds publicly disclosed.
- **Notable Investors/Partners**: 8VC, XYZ Venture Capital, MVP Ventures, Launch Search Partners.
- **Board of Advisors**: Keith Taylor (former CFO, Equinix), Matthew DeNezza (former CFO, Crusoe), Sachin Katti (Head of Industrial Compute, OpenAI), Manoj Jain (former Audit Lead for Equinix, PwC), Heather Paduck (CFO, STACK Infrastructure), David Ferdman (Co-Founder, Primary Digital Infrastructure).
- **Growth Signals**: Launched beta program in January 2026; announced GA of same-day pay app reviews in June 2026; strong customer interest across data center, defense, energy, and manufacturing sectors; advisory board stacked with C-suite veterans from Equinix, Crusoe, STACK Infrastructure, CyrusOne, and OpenAI.

## Competitive Advantages
- **Purpose-built architecture**: Kos is provisioned as an isolated tenant with its own managed identity — the same way a vetted remote hire is onboarded. This provides native auditability, traceability, and strict access controls that general-purpose AI assistants can’t match.
- **No UI paradigm**: Users interact with Kos exactly like a colleague — via email, chat, or video call. No new software to learn or implement.
- **Deep domain expertise**: The company and its advisors have decades of direct experience in infrastructure finance, construction accounting, and capex management — a moat that’s hard for generic AI companies to replicate.
- **Screenshare learning**: Kos learns new workflows by watching a human demonstrate them on a screenshare, then replays the work on a new task — dramatically reducing implementation time.

## Strategic Focus
- **Scale same-day pay app reviews** as the flagship use case for data center operators, then expand across defense, energy, and manufacturing verticals.
- **Deepen ERP integrations** to handle more complex financial workflows (cash forecasting, lender draws, utilities billing).
- **Grow the advisory board** with additional industry leaders to guide product strategy and customer acquisition.
- **Hire founding engineering team** to accelerate product development and scale the platform.

## Why Work Here
- **Founding team pedigree**: Co-founders are Stanford-trained researchers; CEO Tanuj Thapliyal previously founded Spot AI (scaled to 1,000+ enterprise customers). Co-founder Mani is an Olympiad medalist with a Stanford PhD and Microsoft Research background.
- **Mission-driven**: Tackling the overlooked but critical “back-office bottleneck” of America’s industrial revival — a problem with massive economic impact.
- **Early-stage impact**: As a founding engineer, you’d shape the product, architecture, and culture from the ground up.
- **Remote/hybrid**: Not explicitly stated, but the product is built for remote collaboration (Slack, Zoom, email), suggesting a flexible work culture.
- **Notable perks**: Work with a world-class advisory board including C-suite leaders from Equinix, Crusoe, and OpenAI; opportunity to build the world’s first virtual finance employee at the intersection of AI and industrial infrastructure.
