Our Mission and Vision
At Solidgate, our mission is clear: to empower outstanding entrepreneurs to build exceptional internet companies. We exist to fuel the builders — the ones shaping the digital economy — with the financial infrastructure they deserve. To achieve that, we’re on a bold path: to become the #1 payments orchestration platform in the world.
We believe the future of payments is shaped by people who think big, take ownership, and bring curiosity and drive to everything they do. That’s exactly the kind of teammates we want on board.
We’re building the #1 payment orchestrator in the world — and the names behind us prove it. Clients include Bolt, Ajax, Nova Post, MEGOGO. Trusted by giants like J.P. Morgan. Ranked #2 in the “Employer of the Year 2026” award by Forbes Ukraine.
About the Team and Role
This is a foundational hire on our brand-new ML/AI direction at Solidgate — you’ll be one of the first engineers building the function from the ground up, working directly with the Head of ML to shape it.
You’ll help stand up the ML/AI direction from scratch — 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. That’s the space you’ll be building in.
What You Will Own
— Design and build core ML models and pipelines as part of a true greenfield direction, not a maintenance handover
— A real-time ML decisioning system with direct revenue impact
— A recommendation engine and other ML-driven features that lift merchant conversion and revenue
— Hands-on experimentation — from idea, through A/B testing, to production
— Integrations of cutting-edge AI technologies to drive innovation
— Close 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 technical results to both engineers and cross-functional stakeholders
Our Ideal Candidate
— 4-5+ years in ML, with hands-on production experience
— Track record of shipping ML models end-to-end, from idea to production, in a real product environment
— Strong data science fundamentals; a degree in a quantitative discipline is a plus
— Hands-on experience designing and running experiments, plus A/B testing and experimentation design
— Feature engineering on high-cardinality transactional data
— Proactive and self-driven, comfortable working closely with a wide range of stakeholders
