AI and Agentic AI Risk Management Senior Specialist

This is a senior, hands-on technical position. You will help define what model risk management looks like for AI and Agentic AI at Nubank — building and enhancing the frameworks, not just inheriting them. You will perform independent assessments of AI systems for quality, behavior, and robustness, and help design the guardrails and platform-level controls that govern their safe use. You'll act as a credible technical peer to first-line engineering and AI development teams, providing practical guidance on AI risk without slowing responsible innovation. This role focuses on AI quality, agentic behavior, and platform controls; cybersecurity, data privacy, and fraud-specific matters sit with partner functions and are out of scope.

Responsibilities

Build and continuously enhance the risk management framework for AI and Agentic AI systems, including inventory standards, assessment methodologies, control design, and issue management; Inventory and map Nubank's AI use cases to surface gaps, materiality, and the most critical risks, and define prioritized mitigation actions; Assess whether first-line monitoring is effective, proportionate to model risk, and sufficient to keep AI systems fit for purpose over time; Perform independent technical assessments across generative AI and agentic workflows, covering data, assumptions, methodology, testing, behavior, and monitoring; Assess risks in LLM-powered applications, including RAG pipelines, tool use, autonomy boundaries, model/agent quality, human oversight, and hallucination risk; Identify and document model limitations, failure modes, and emerging AI risks, including drift, instability, fairness, and robustness concerns; Influence first-line teams on platform architecture and embedded controls for the safe deployment and monitoring of AI; Build Key Risk Indicators (KRIs) and metrics for continuous monitoring of AI risk; Develop tools, evals, analyses, and playbooks (including AI-enabled automation) to improve the speed, scale, and effectiveness of AI governance and validation; Serve as a trusted advisor across the AI/ML lifecycle, evaluating new use cases for materiality and governance requirements prior to deployment; Discuss and report AI risk status and independent opinions to stakeholders, including senior managers and, where relevant, regulators; Champion AI risk management as a strategic enabler of safe and scalable AI adoption; Work in a multicultural, diverse, and highly skilled environment

Requirements

Bachelor's or master's degree in a quantitative field (computer science, data science, statistics, mathematics, engineering, or related); Hands-on AI/ML experience developing or validating AI/ML models and systems, ideally moving from an AI / Machine Learning Engineer background into model risk, governance, or risk management; Proficiency in Python, SQL, and modern ML tooling; familiarity with LLMs, RAG systems, prompt engineering, and AI agent frameworks; Experience evaluating and testing ML and generative AI systems, including custom evals, benchmarking, stress testing, and drift/degradation monitoring; Demonstrated experience in risk identification, control definition, and framework building; understanding of model risk governance principles and independent effective challenge; Experience working with large datasets and building dashboards and analyses to support risk visibility; High agency and adaptability; Influencing skills; Strong written and verbal communication skills; Advanced or fluent English

Nice to have

Experience in a 2nd or 3rd line of defense; Familiarity with regulatory Model Risk Management and AI frameworks (e.g., SR 11-7 / SR 26-2 / OCC 2011-12, NIST AI RMF, EU AI Act)
