Senior AI & ML Engineer - AML Search Quality

• Drive modeling and experimentation for SEON's fuzzy matching and AML screening quality, turning ambiguous problems into well-defined approaches and carrying them from experiment through release and operation
• Build evaluation datasets and metrics, using offline and online signals, to measure match quality and guide model and configuration changes
• Design scoring and ML approaches that fit real-time decisioning constraints, balancing match quality, performance, cost, and operational overhead
• Own the production quality of your models and configurations, including monitoring for data and concept drift, on-call participation, and incident follow-up
• Investigate customer-reported matching issues together with Product and Customer Success, and keep the customer voice in prioritization
• Collaborate with Product, QA, Architects, DevOps, and Customer Success
• Capture learnings from experiments so they get reused, and introduce AI tools and techniques where they provide clear value
• Mentor teammates and raise the bar for data science practice across the team
• WHAT YOU’LL BRING:
• 5+ years of experience in data science or machine learning, delivering models to production
• Strong Python skills
• Strong command of statistical analysis and experiment design, including offline and online evaluation of search or matching quality (for example precision and recall trade-offs)
• Experience with NLP or text-based machine learning, such as text classification, named entity recognition (NER), or text matching
• Experience owning the full lifecycle of data-driven systems, from data and experimentation to deployment and monitoring, anticipating data drift, leakage, and bias
• Solid background in data analysis and SQL, with a working understanding of backend services and APIs
• Experience with non-relational or search databases, ideally Elasticsearch
• Working experience with a major cloud provider (ideally AWS), including deploying models and data pipelines on it
• Clear communication: you can explain modeling trade-offs to Product and non-technical stakeholders
• A track record of turning ambiguous problems into end-to-end solutions, and of spotting delivery risks early and raising them with a proposed mitigation

Amazing if you also have

• Prior experience in AML, KYC, or another regulated financial services domain
• Experience driving cross-team technical work
• Experience using AI-assisted development tools and helping a team apply them with good judgment
