[Hiring] Senior Machine Learning Engineer @Solidgate

Role Description

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.

• Help stand up the ML/AI direction from scratch — on top of 20M+ orders and 100M+ transactions a month.
• Build a recommendation engine and a real-time system that decides which acquiring bank routes each transaction.

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.

Qualifications

• 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.

Benefits

• 30+ days off.
• Unlimited sick leave.
• Free office meals.
• Health coverage.
• Apple gear to keep you productive.
• Courses, conferences, sports, and wellness benefits — all designed for ideas, focus, and fun.
