Role Overview Nium Brazil is seeking a Cybersecurity Manager to own the organisation’s cybersecurity compliance obligations under Resolution BCB 85/2021 and act as the primary point of accountability for cyber risk in Brazil. Reporting to the Country Manager with a dotted reporting line to the Group CISO, this role sits at the intersection of local regulatory compliance and hands-on security operations in a fast-growing, regulated payment institution. This is an opportunity for a cybersecurity professional to step into a high-impact, visible role with broad cross-functional exposure — shaping how Nium Brazil manages cyber risk as the business scales. Key Responsibilities Regulatory Compliance & Governance • Ensure the Group’s cybersecurity policy remains fully aligned with BCB Resolution 85/2021 and any subsequent regulatory updates. • Act as the designated local lead for all BCB cybersecurity obligations, coordinating with Group security teams to meet local requirements. • Produce regular management reporting on the organisation’s cybersecurity posture, open risks, and any incidents. • Track regulatory changes to cybersecurity requirements and lead the assessment and implementation of any operational or process impacts. Access Controls & System Security • Enforce local access controls across critical systems, ensuring user permissions are regularly reviewed and appropriately restricted. • Oversee identity and access management for Brazil-based users and systems, working with Group IT to align with global standards. • Manage privileged access reviews and ensure segregation of duties is maintained across key operational functions. Incident Response & Threat Management • Act as first responder to local cybersecurity incidents — logging, triaging, escalating, and reporting within required regulatory timeframes. • Maintain and regularly test Brazil’s incident response and business continuity procedures in line with BCB guidance. • Coordinate vulnerability assessments and penetration testing programmes with the Group technology team, tracking remediation to closure. • Monitor threat intelligence relevant to the Brazilian payments landscape and proactively brief senior leadership on emerging risks. Third-Party & Vendor Risk • Manage third-party and vendor cybersecurity risk, ensuring external partners and service providers meet Nium’s security standards and BCB requirements. • Conduct or oversee cybersecurity due diligence for new vendor onboarding and periodic reviews of existing suppliers. • Maintain a register of critical third-party relationships and their associated cyber risk profiles. What We’re Looking For Experience • 3–5 years of experience in a cybersecurity, information security, or technology risk role within a regulated financial institution or payment institution. • Demonstrable knowledge of BCB Resolution 85/2021 and related cybersecurity regulatory requirements in Brazil. • Hands-on experience with incident response, access management, vulnerability management, and third-party risk. • Experience operating as a first line of defence in a regulated environment. Skills & Knowledge • Fluency in Portuguese and English. • Strong understanding of cybersecurity frameworks and controls relevant to financial services (e.g. ISO 27001, NIST). • Ability to translate complex regulatory requirements into practical, operational controls. • Confident working cross-functionally with technology, operations, legal, and product teams. • Familiarity with LGPD (Lei Geral de Proteção de Dados) obligations in a financial services context. Personal Attributes • Highly organised with strong attention to detail. • Comfortable working in a fast-paced, evolving regulatory environment. • A self-starter who can take ownership of obligations and drive them to resolution. • A collaborative team player who can influence without authority. • Strong communicator, able to present technical risk topics clearly to non-technical stakeholders.
