About The Team

Our data science team sits at the center of Rain's product. We're a small, senior team embedded in a fast-moving fintech, which means the models we build go directly into production decisions — credit risk scoring, balance forecasting, personalized financial insights — and the impact is immediate and measurable.

We work closely with product, engineering, and compliance, and we operate like owners: defining problems, building solutions, and monitoring them in production. If you're the kind of data scientist who gets energized by seeing your work move the needle on a real product — not just a dashboard — this team was built for you.

This role is based remotely in EMEA. You'll be a key early hire on our international data science presence, working across time zones with our U.S.-based team and contributing to how we scale our ML function globally.

What You’ll Do

Run end-to-end experiments: feature engineering, model selection, A/B testing, and production monitoring
Build and maintain scalable, well-documented pipelines that keep models healthy in production
Design, train, and deploy ML and Agentic models that drive core product decisions, including credit risk, forecasting, and personalized recommendations
Collaborate with product and engineering to translate business problems into well-scoped modeling tasks
Communicate model behavior and findings to both technical and non-technical stakeholders

Who You Are

You thrive in ambiguity — you can take a loosely defined business problem, ask the right questions, and turn it into a well-scoped modeling task without waiting for a perfect brief
You are a strong cross-functional collaborator who builds trust with product, engineering, and compliance partners and can speak their language
You have a bias toward shipping — you know when a model is good enough to get into production and how to iterate from there, rather than optimizing in isolation
You take ownership end-to-end: from a messy raw dataset to a monitored production model, you don't hand things off and walk away
You communicate with clarity — you can walk a skeptical stakeholder through a model's tradeoffs without leaning on jargon
You care deeply about model behavior in the real world, not just on a held-out test set
You mentor and elevate the people around you, and you're energized by working somewhere where the stakes are real

Required Technical Qualifications

Python and core ML libraries, (pandas, scikit-learn, PyTorch, or TensorFlow )
SQL and working with large, complex datasets
Experience with LLMs and NLP techniques (fine-tuning, RAG, prompt engineering or similar)
Communication skills to explain models trade offs
Solid understanding of statistical modeling, experimentation, and model evaluation
Experience taking models from prototype to production
Familiarity with agentic frameworks (e.g. Langchain) and agent orchestration and evaluation
