Join one of the fastest growing rewards/fintech startups in the world -
Benjamin Backed by Play Ventures and F4 Fund, we're all about making everyday
actions rewarding. We're looking for an experienced Senior Data Scientist to
help us take things to the next level.

At Benjamin, we give users real cash rewards—what we call MoMos (Money
Moments)—for things they’re already doing. From playing games and watching ads
to everyday card purchases with cash back, we’re all about putting money back in
people’s pockets.

What you’ll do

* Find and frame the high-impact problems, figure out which lever moves the
metric before writing a line of model code, so every project has a clear "so
what?"
* Optimize rewards and incentives directly — uplift modeling and reward/pricing
optimization that grows engagement and conversion without wasting spend
* Recommend and rank offers and content in real time — the right offer for the
right user at the right moment
* Own experimentation and measurement across product and paid acquisition —
causal impact, incrementality,



and attribution (MMM and multi-touch)
* Take problems zero-to-one — turn a blank-slate idea into a production data
product, not a Confluence page
* Build features, labels, training datasets, and evaluation pipelines
* Ship models as batch jobs, APIs, services, or product features — and keep
training, validation, and inference running reliably without hand-holding
* Mentor the team and set the standard for ML engineering at Benjamin

What we’re looking for

* Strong statistical judgment: you know experimentation, causal inference, and
model evaluation cold, and you use them to decide what's actually working
* A track record of models that moved a real business metric. You frame
problems around impact and can answer "so what?" about your own work
* Experience with recommendations, ranking, forecasting, uplift, or causal
methods
* You've operated reliable pipelines in production, not just built them once
* Comfortable getting y
