• Design and implement big data machine learning solutions using technologies such as Spark, and Kafka for real-time data processing and analytics.
• Explore and integrate new big data technologies and tools into the existing data ecosystem to improve data analytics and model development processes.

Agentic AI & MCP (Model Context Protocol)

• Design, build, and productionize agentic AI solutions (single- and multi-agent) for payment use cases such as risk & fraud detection, dispute/chargeback workflows, merchant support, monitoring, and data quality triage.
• Implement and maintain MCP servers/clients to safely expose tools, data sources, and actions to models; define resources, prompts, schemas, and tool contracts aligned with Nuvei security, compliance, and observability standards.
• Establish evaluation and LLM observability for agents (task success, reliability, latency, cost, safety), with structured telemetry, tracing, and automated regressions.
• Implement guardrails and human-in-the-loop mechanisms (policy checks, approvals, safe tool sandboxes, rate limiting, and Write clear documentation and runbooks for agent behaviors, MCP endpoints, versioning, and incident response.

Qualifications

• A Bachelor's or Master's degree in Computer Science, Statistics, Mathematics, or a related field with a strong focus on machine learning or artificial intelligence.
• At least 3 years of hands-on experience in developing and implementing machine learning models, with a strong preference for candidates with experience in generative AI.
• Proficiency in programming languages used in data science, such as Python and familiarity with machine learning libraries (e.g., scikit-learn, TensorFlow, PyTorch).
• Experience with data manipulation and analysis tools, including SQL, and experience working with large data sets.
• Strong understanding of machine learning principles and algorithms, including supervised and unsupervised learning. Demonstrated ability to apply machine learning techniques to real-world problems, from initial concept through data preparation, model development, and deployment.
• Excellent analytical and problem-solving abilities, with a keen attention to detail and a data-driven approach to decision-making.
• Exceptional communication skills, with the ability to convey complex data insights to both technical and non-technical stakeholders.
• Familiarity with cloud computing services (AWS, Azure, or Google Cloud) and experience deploying models in a cloud environment is a plus.
• A track record of continuous learning and adapting to new technologies and techniques in data science and AI.

Agentic AI & MCP (Model Context Protocol)

• Demonstrated experience designing and operating agentic AI systems in production, including planning, tool calling, memory management, and failure recovery.
• Hands-on experience with MCP concepts (servers, tools/resources, prompts, sessions) or similar tool-exposure protocols; ability to define JSON-schema contracts and enforce authorization, auditing, and quota controls.
• Practical knowledge of orchestration frameworks (e.g., graph-based or multi-agent frameworks) and integrating agents with microservices, webhooks, queues, and event streams.
• Experience with RAG, vector stores, and retrieval strategies optimized for tool-using agents; familiarity with evaluation frameworks and LLM telemetry/tracing.
• Understanding of security and governance for AI systems (PII handling, secrets management, RBAC/ABAC, row-level security, data residency).
• Nice to have: familiarity with LLM tool-use ecosystems, prompt engineering best practices, cost/latency optimization, and blue/green or canary deployment strategies for agent updates.
