> full description

We're an early-stage product company building an AI-powered analytics platform for the iGaming industry. Users get answers from their data in plain English — an LLM turns questions into validated SQL over a large data warehouse — alongside a set of analytics dashboards and data pipelines. It's live in production.

You'd be our first dedicated engineer, working directly with a technical founder (product) and an experienced CTO (architecture + code review) — with a real path to Tech Lead as the team grows. You won't be flying solo, and you'll help shape the architecture, not just maintain it.

 

What you'll do

 

  • Build and ship features across the backend and the dashboard.
  • Write correct, performant SQL against a large Postgres warehouse — the numbers drive real decisions.
  • Extend the LLM→SQL pipeline and the analytics APIs behind the product.
  • Own reliability, testing, and deploy stability as we scale.
  • Maintain and extend the React / TypeScript front end.

     

Stack

 

  • Backend: Python 3.12 + FastAPI (async, SQL-first with asyncpg — no ORM).
  • Data: large Azure PostgreSQL warehouse (tens of millions of rows) + nightly aggregation pipelines.
  • AI: Anthropic Claude (natural-language → SQL, agent workflows).
  • Frontend: React 18 + TypeScript + Vite, shadcn/ui + Tailwind, TanStack Query, Recharts.
  • Infra: Azure, Redis, Docker, GitHub Actions.

Note: the data-science/ML models are owned by the founder — you won't build or maintain those.

 

You'll thrive here if you have

 

  • Strong SQL and relational-DB skills (Postgres a plus) — the single most important thing.
  • Solid Python, ideally with an async framework (FastAPI).
  • Good React + TypeScript.
  • A correctness-first instinct for data, and the ability to pick up a fast-built codebase and make it solid.
  • Comfort with cloud + CI/CD (Azure a plus) and Docker.

     

Nice to have

 

  • LLM app experience (Anthropic/OpenAI, NL→SQL, RAG).
  • Data engineering / BI / warehousing background.
  • iGaming, fintech, or marketplace domain experience.

 

Why join

 

  • A live, revenue-generating product — early enough to shape it.
  • A clear growth path to Tech Lead.
  • Modern stack: large data warehouse + production LLM pipeline + polished React app.
  • Real support: a technical founder on product, an experienced CTO on engineering.
