You will communicate progress and results to stakeholders, maintain clear documentation, and help drive innovation in payments and banking operations.

Job Responsibilities:

• Deliver machine learning and AI solutions for payments and banking operations, from discovery to production rollout
• Apply agentic engineering practices to build LLM-powered workflows and evaluate their quality, safety, and reliability
• Contribute to deployment workflows including containerization, CI/CD, automated testing, versioning, monitoring, and rollback procedures
• Develop scalable and secure ML/LLM services integrated with strategic platforms and downstream consumers
• Partner with product, operations, risk and control, and technology teams to clarify requirements and deliver data-led improvements
• Build reusable components such as feature engineering pipelines, evaluation harnesses, and orchestration patterns
• Participate in code and design reviews; contribute to best practices, documentation, and team standards
• Communicate with technical and non-technical stakeholders, translating model outputs into practical decisions
• Maintain documentation such as model cards, runbooks, experiment notes, and operational procedures

Required Qualifications, Capabilities, and Skills:

• Relevant industry experience in applied machine learning, data science, ML engineering, or related roles
• Bachelor’s or Master’s degree in a quantitative field or equivalent practical experience
• Strong understanding of machine learning fundamentals and applied data analysis skills
• Experience designing evaluations and measuring impact in real-world settings
• Experience deploying and operating ML models or ML-enabled services in production, including monitoring and troubleshooting
• Strong Python software engineering skills, including modular code, testing, debugging, and performance awareness
• Working knowledge of ML engineering/MLOps concepts, including training vs. serving, batch vs. real-time, orchestration, scalable data processing, and familiarity with model/prompt versioning and governance
• Ability to align evaluation and guardrails to business goals and identify potential unintended outcomes
• Experience operating in regulated or control-conscious environments with attention to model risk, privacy, security, and audit-ready documentation
• Strong stakeholder management and teamwork skills, with the ability to drive outcomes in cross-functional teams

Preferred Qualifications, Capabilities, and Skills:

• Hands-on experience with NLP and/or generative AI, including LLMs, RAG, tool/function calling, and agentic workflows
• Familiarity with agentic building blocks such as orchestration frameworks and context/memory patterns; awareness of interoperability approaches
• Experience deploying to AWS (e.g., SageMaker and/or Bedrock) and operating production ML/LLM workloads with attention to cost, latency, performance, security, and scaling
• Experience integrating human-in-the-loop review and user feedback into iterative improvement, such as labelling strategies, QA workflows, and preference signals
