About The Position

Coinflow is seeking a Machine Learning Engineer to help build the intelligence layer that powers our platform.
This is a zero-to-one role. You will be the first dedicated ML hire and will own how data and machine learning are developed and applied across Coinflow. You’ll explore large-scale transaction and behavioral data, build models and analytical systems, define what success looks like, and embed intelligence directly into our products and internal tooling.
The ideal candidate is deeply curious, excited to experiment, and motivated by building something that does not yet exist.

• Experience building models or data-driven systems that operate in real products
• Comfort working with ambiguous problems and creating structure where none exists
• Strong communication skills and experience collaborating cross-functionally
• High ownership mindset with genuine curiosity about messy, real-world data

Nice To Haves

• Experience building decisioning, optimization, fraud, risk, or other payments systems
• Experience in fintech, payments, or other financial services environments
• Experience as an early data/ML hire at a startup
• Experience working with high-volume behavioral or financial data

Responsibilities

• Build and evolve machine learning models and analytical systems that support platform decisioning and product intelligence
• Establish the foundation for data and machine learning practices across the company
• Define, own, and evolve core metrics across platform health, performance, and risk
• Explore transaction and behavioral data to uncover patterns, signals, and new insights
• Partner closely with Engineering, Product, and Operations to turn open-ended problems into real systems
• Design how models and data systems are evaluated, improved, and trusted over time
• Build internal workflows and tooling that support operational and product teams
• Help shape Coinflow’s long-term data and machine learning roadmap

Benefits
