💻 Job Title: AI (Data) Engineer
💰 Salary: up to ~£120k + profit share
📈 Equity: 0.75 - 1%
📍 Location: Old Street (4-5 office days/week)
🔐 Company: Data processing AI Agents
👥 Team: ~5
💸 Funding: Pre-seed
About the company
This early stage start-up is processing hundreds of thousands of unstructured financial documents into clean, structured datasets for some of the world's largest financial institutions - producing the output of 50, with a team of 5.
Forecasting £1.5m revenue within their first 12 months, they have an immense potential - not based on hype or inflated valuations, but rather achieving mega productivity through intelligent application of AI agents.
Their mid term goal is ~£50m revenue with a sub-30 person team. What's in it for you?
* Profit share. Cash in your account on regular basis - not a promise of a huge payout IF the company succeeds and sells.
About the role
You'll own data infrastructure end-to-end - ingestion, transformation, storage, delivery.
The current agent system works. Your job is to scale it: more documents, more asset classes, more clients. You'll make architecture decisions, push the boundaries of agentic tooling and ship data as a product to institutional buyers who rely on it for decisions that move millions.
Full ownership from day one, with a genuine progression trajectory for the right person.
✅ Must have requirements:
* Roughly 3-6 years experience building performant data pipelines and ML systems in production
* Genuinely AI-native experience: Claude Code, Cursor or equivalent as your daily environment - not occasional experiments
* Python, Postgres, async, queues - fluent and battle-tested
* Experience in a small team (2-30 people) where you owned the whole function
* Data quality obsessive - inconsistencies bother you until they're fixed
👍 Bonus points for:
* Experience at a financial data provider (Bloomberg, Refinitiv, Preqin, FactSet etc.) or quant finance
* Experience with LLMs in production / agentic workflow design
* Web scraping and document parsing at scale
