About Costory:

• We’re building the FinOps Assistant we wish we had as large cloud clients. After managing multi-million dollar budgets across GCP, AWS, and Datadog, we know how painful cloud cost management can be. FinOps often falls on senior engineers, forced to manually monitor costs and investigate spikes with little context.
• We believe FinOps and engineering teams shouldn’t waste time digging through billing consoles and dashboards. LLMs alone won’t solve anomaly detection or cost allocation—the real challenge is adding context to messy billing data. That’s why we’re building an agent that correlates costs with technical and product events, explains changes, and surfaces insights directly where teams work, so they can focus on optimization.
• Long-term, our vision is to shift FinOps left, just like SecOps. Engineers should understand cost impact as they build, not after the fact. Costory becomes their co-pilot—helping them make smarter trade-offs between performance, reliability, and cost early in the development cycle.

Your Mission:

As a Full Stack Engineer, you will be responsible for building the interfaces and APIs that turn complex cloud data into intuitive, actionable stories. You’ll bridge the gap between our data engine and the end-user, ensuring that a DevOps lead or a CFO can understand their cloud spend in seconds.

What You’ll Be Working On

Project 1: The Ultimate FinOps Interface

• The Goal: Ship features that make Costory the most intuitive FinOps tool available.
• The Focus: You will work on reducing "Time to Information." You'll build high-performance UI to turn massive datasets into clear, actionable insights. Your mission is to make complex cloud billing feel "easy" for the end-user and the most intuitive.

Project 2: Ecosystem & Agent Integrations

• The Goal: Ensure our users don't lose a second "doing" FinOps by bringing the data to them.
• The Focus: You will build and ship integrations for Slack, Microsoft Teams, and MCP (Model Context Protocol). You’ll leverage Node.js, Prisma, and LLM APIs to push critical cost alerts and automated reports directly into the tools engineers and finance teams already use daily.

Your Toolkit (Our Tech Stack)

• Frontend: React, Mantine UI, TanStack Query (React Query).
• Backend: Node.js (Express), Prisma ORM.
• Database/Data: PostgreSQL, BigQuery.
• Cloud: Google Cloud Platform (GCP).
• Analytics: PostHog
