I'm working with a lean team of 10 that is building the operating system for Private Equity. They’ve grown 15x in ARR in 12 months and their customers are top-tier funds managing over £100bn. No middle managers, no agile coaches, just a high-leverage team shipping high-stakes code.
The Tech & The Work
- The Stack: Python (FastAPI), React (TypeScript), Postgres, Docker.
- The AI: Sophisticated RAG pipelines using LlamaIndex, LangChain, and PyTorch. This isn’t an OpenAI wrapper; it’s building "hallucination-free" systems for massive financial data sets.
Velocity: You’ll own features end-to-end. You’ll design architecture with the CTO and see your code impact £100k+ deals within days.
Who You Are
- "Cracked": You’ve built from 0 to 1. You don’t need a PRD to start.
- High Agency: You see a bug or a missing feature and you kill it. You don’t wait for permission.
- Product-Minded: You care more about solving the user’s problem than the library you’re using to do it.
Don’t apply if: You want a 9-to-5, a single-layer stack, or a Jira-heavy environment. This is for people who want to move fast and own a meaningful slice of a company.
