About the teamAs Nubank expands its footprint into the US, we are seeking a visionary, highly specialized US Chief Information Security Officer (CISO).
This is not a traditional operational CISO role. You will serve as the executive pillar for Nubank’s US strategy, bridging the gap between traditional financial regulations and modern, hyper-scalable crypto and AI technology platforms. You will act as the point of accountability for US regulatory bodies, lead governance transformations, and oversee critical cross-functional security domain leadership.
We are looking for a security leader who balances deep traditional banking compliance expertise with a forward-looking understanding of cryptocurrency protocols and artificial intelligence security.
About the roleAs the US CISO, you will architect, establish, and operationalize a unified US security and compliance posture. You will protect customer trust, satisfy strict US regulatory frameworks (e.g., OCC compliance), and secure frontier technology initiatives ensuring Nubank’s platform remains resilient, future-proof, and compliant as we scale globally.
Key responsibilities and ExpectationsUS Regulatory & Regulatory Agency Liaison: Serve as the primary US security authority and point of contact for regulators (e.g. OCC). Oversee all mandatory statutory disclosures, including financial and IBFR background reviews.
Crypto & Web3 Product Defense: Partner with crypto product and infrastructure teams to secure future-proof financial technologies, translating complex blockchain architectures into compliant, enterprise-grade risk frameworks.
Governance, Risk, and Compliance (GRC) Transformation: Uplevel Nubank’s GRC program to support multi-geography scaling.
AI Security Frameworks: Lead the strategic security response for AI initiatives—from developer workflows and engineering toolsets to model integrity and deployment risks.
Insider Threat Program Development: Design, build, and deploy an end-to-end enterprise Insider Threat program across first and second lines of defense in close partnership with Risk and Legal teams.
Executive Leadership Experience: 15+ years in Information Security, with significant experience operating at an executive, director, or CISO level within FinTech, Banking, or Digital Assets.
US Financial Regulatory Expertise: Deep hands-on experience navigating US regulatory environments, specifically working with the OCC, statutory disclosure processes, and financial institution compliance.
Cryptocurrency & Blockchain Security: Demonstrated domain expertise in cryptocurrency security, decentralized finance, or digital asset platforms. Experience at leading crypto-native institutions or hyper-growth FinTechs is highly valued.
AI Security Strategy: Familiarity with modern AI security risks, LLM integrations, safe code generation tools, and model security.
GRC Upleveling: Proven track record of rebuilding or scaling GRC frameworks within complex, multi-national organizations.
Executive Communication: Exceptional communication skills needed to interface effectively with regulatory examiners, executive leadership, and board members.
Fluency in English is required; Portuguese and/or Spanish are a plus.
Strong people leadership at scale, including developing managers and leading teams of differing maturity through change and ambiguity.
Excellent stakeholder management and communication, with maturity in negotiation and conflict resolution across senior cross-functional partners.
A pragmatic, hybrid profile, balanced across people leadership, product sensibility, and technical depth rather than weighted to any single one. A genuine product mindset focused on customer and agent outcomes, with the technical depth to raise the bar in architectural discussions.
