Founding ML Engineer, Forecasting
About the role
Tellwise forecasts an individual's cashflow for the weeks ahead. The predictive engine is the product: recurring-pattern detection, trend projection, the confidence band, and the warnings that fall out of it. Every number a warning shows is computed here, not by a language model.
You would be the third engineer. The work decides whether people trust the forecast. A confident number that turns out wrong is worse than a wider range that turns out right.
What you would own
Own the forecast: recurring detection, projection, volatility and the confidence range.
Build the evaluation set. Every change is measured against histories with known outcomes before it ships.
Keep the forecast honest when the history is thin or the income is irregular.
Make ingestion survive the dozen ways banks export a CSV.
What we are looking for
Five or more years building systems other people depend on, with real time-series or forecasting work.
You have opinions about evaluation that came from being burned.
You write TypeScript comfortably, or you will within a fortnight.
You care about the difference between a demo and a thing someone checks before payday.
How hiring runs
A thirty-minute call with a founder, then a paid work session on a real problem from our backlog (three to four hours), then two conversations with people you would work alongside. Four steps, usually inside two weeks. We tell you where you stand at every one, and we reply either way.

About Tellwise
Tellwise is an AI-powered consumer fintech company helping individuals and freelancers understand what their money may look like in the weeks ahead. Our platform analyzes transaction history, learns recurring spending patterns, and forecasts future cashflow so users can identify tight weeks, potential overdrafts, subscription increases, and unusual spending before they become bigger problems. Tellwise combines predictive machine learning with clear, plain-language explanations. Forecasts, confidence ranges, warnings, and spending anomalies are calculated from transaction data, while AI helps explain those insights in a way that is easy to understand. Users can add transaction data through CSV or paste-based workflows, allowing Tellwise to identify recurring charges, project balances forward, monitor changes in spending behavior, and surface relevant financial insights. Our goal is simple: help people see money problems coming earlier and make better-informed financial decisions with greater clarity. Tellwise provides financial information and forecasting tools, not financial advice.
