[Hiring] Senior ML Engineer @Solidgate

Role Description

This is a foundational hire on ML/AI direction at Solidgate — you'll be one of the first engineers building the function from the ground up, working closely with the ML team to shape it.

• 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
• 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 will help with data and MLOps) 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 or Data Science, with hands-on production experience in classical predictive models (e.g. credit scoring, fraud, risk, recommendations, pricing)
• Track record of shipping ML models end-to-end, from idea to production, in a real product environment and being able to show their business impact in numbers (conversion, approval rate, losses, revenue)
• Strong data science fundamentals
• Hands-on experience with A/B testing and experimentation design
• Feature engineering on high-cardinality transactional data
• A driver mindset: you can walk into a greenfield space, figure out what to build, propose it, and own it through delivery
• Great communication skills and comfort working with a wide range of stakeholders

Requirements

• Experience in fintech, payments, fraud, or risk (nice to have)
• Real-time / low-latency ML serving (nice to have)
• A master's or PhD in a quantitative discipline (nice to have)

Benefits

• Founding direction: You'll help build the function, the team, and the standards from day one, working alongside the Head of ML
• Great product: We’ve built a fintech powerhouse that scales fast. Solidgate isn’t just an orchestration player — it’s the financial infrastructure for modern Internet businesses.
• Impact you can measure: Every prediction has a clear outcome — approved or declined — which makes payments one of the few domains where ML ROI is provable per transaction.
• Scale: You'll work with 20M+ orders and 100M+ transactions monthly, 100+ payment methods and providers.
• Top-tier tech team: You'll lead and learn alongside engineers who hold the bar high and ship at fintech scale.
• Work from anywhere: Fully remote, no relocation required. We also have offices in Poland, Cyprus, and Ukraine.
• 30+ days off, unlimited sick leave, free office meals, health coverage, and Apple gear to keep you productive.
• Courses, conferences, sports and wellness benefits — all designed for ideas, focus, and fun.
