About the Team and Role

This is the first dedicated ML leadership role at Solidgate — you wont inherit a function, youll create one.

Youll stand up the ML/AI direction from scratch — the vision, the architecture, and the team — on top of 20M+ orders and 100M+ transactions a month. The next big step is a recommendation engine and a real-time system that decides which acquiring bank routes each transaction. Thats the gap youre here to fill.

What You Will Own

— The vision, architecture, and roadmap for ML/AI at Solidgate — a true greenfield direction, not a maintenance handover

— Building and leading the team, combining new hires with engineers who already carry a deep payments context

— A real-time ML decisioning system with direct revenue impact

— A recommendation engine and other ML-driven features that lift merchant conversion and revenue

— Integrations of cutting-edge AI technologies to drive innovation

— Partnership with Product, Engineering, and the Data Platform team (who handle ML Ops) to solve hard modelling problems and build orchestrated training and analytics pipelines

— Clear communication of complex results to audiences from engineers to executives

Our Ideal Candidate

— 5+ years in ML

— Proven experience building and scaling an ML function — youve done founding-level work before, not just contributed to an existing one

— Strong data science fundamentals, a masters or PhD in a quantitative discipline

— Hands-on experience designing and running experiments, plus A/B testing and experimentation design

— Feature engineering on high-cardinality transactional data

— You take the lead proactively, from idea to production, and work fluently across a wide range of stakeholders
