Blockchain Security Professional information

What is a blockchain security professional?

Blockchain Security Professionals are experts who specialize in ensuring the safety and integrity of blockchain systems, smart contracts, and decentralized applications. They assess vulnerabilities, conduct security audits, and implement protocols to protect against hacks, fraud, and other cyber threats specific to blockchain technology. Their responsibilities also include monitoring networks for suspicious activity and staying updated on the latest security risks in the rapidly evolving blockchain landscape.

What are some common challenges faced by blockchain security professionals in securing decentralized applications (dApps)?

Blockchain Security Professionals often encounter challenges such as identifying and mitigating smart contract vulnerabilities, ensuring the secure integration of off-chain and on-chain components, and keeping pace with rapidly evolving attack vectors. Collaboration with developers is crucial, as security reviews and audits must be integrated throughout the development lifecycle. Additionally, the decentralized nature of blockchain systems can make incident response and vulnerability remediation more complex, requiring proactive planning and continuous monitoring.

What are the key skills and qualifications needed to thrive as a blockchain security professional, and why are they important?

To thrive as a Blockchain Security Professional, you need expertise in cryptography, smart contract auditing, and blockchain network protocols, typically supported by a degree in computer science or cybersecurity. Familiarity with tools like MythX, Slither, and platforms such as Ethereum or Hyperledger, as well as relevant certifications like Certified Blockchain Security Professional (CBSP), is common. Strong analytical thinking, attention to detail, and effective communication skills help professionals identify vulnerabilities and convey complex risks to stakeholders. These skills are critical to ensuring the integrity, confidentiality, and reliability of blockchain-based systems in an evolving threat landscape.

About the team

As 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 role

As 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 Expectations
  • US 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.

Qualifications Professional Experience & Education
  • 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.

Competencies & Attributes:
  • 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.

Our Benefits
  • Top Tier Medical Insurance

  • Top Tier Dental and Vision Insurance

  • 401(k) matching

  • 20 days time off, 14 company holidays, and great culture that emphasizes work life balance.

  • Life Insurance and AD&D

  • Nucleo - Our learning platform of courses

  • NuLanguage - Our language learning program

  • NuCare - Our mental health and wellness assistance program

  • Extended maternity and paternity leaves

  • Saving Plans - Health Saving Account and Flexible Spending Account

  • Twice a week in the office + quarterly trips to Sao Paulo (Brazil) to build relationships with coworkers.

Our recruitment process may involve the use of artificial intelligence–enabled tools, such as automated interview transcription and analysis, to support the evaluation process. Artificial intelligence is not used to make final hiring decisions; all decisions are made by human reviewers.
