About Cleo
At Cleo, we're not just building another fintech app. We're embarking on a mission to fundamentally change humanity's relationship with money. Imagine a world where everyone, regardless of background or income, has access to a hyper-intelligent financial advisor in their pocket. That's the future we're creating.

About the Role
You will be part of the team developing and maintaining decisioning systems that are crucial to Cleo's core product, directly influencing user experience, growth, and profitability.
Your main responsibility will be integrating ML-driven credit and eligibility models into our Ruby on Rails monolith. These models, developed in Python by ML engineers and data scientists, require scalable, robust integration. You will manage the entire lifecycle from data ingestion to monitoring and observability.
You will collaborate closely with ML engineers, analysts, and PMs to ensure model outputs are accessible, behavioral anomalies are debugged, and stakeholders have the necessary tools to understand decision-making processes.
You will also contribute to our Ruby chapter, enhancing our monolith for better performance and maintainability.

* Comfortable working in complex domains; exposure to Python and ML concepts is a plus.
* Strong focus on system reliability, observability, and deployment best practices.
* Data-awareness, understanding data lifecycle and transformations.
* Excellent collaboration skills with cross-functional teams.
Our Tech Stack
Built as a Ruby on Rails monolith with a React Native frontend (TypeScript), leveraging Python for ML, PostgreSQL, hosted on AWS. We deploy multiple times weekly, with automated CI/CD pipelines, peer reviews, and ongoing refactoring towards modular architecture.
What You Get
