• Gestão de Incidentes: Liderar a resposta técnica a incidentes de segurança complexos (Ransomware, APTs, Insider Threats), desde a detecção até a lição aprendida (Post-Mortem). • Threat Hunting: Realizar caça proativa de ameaças na rede e nos endpoints, partindo de hipóteses baseadas em Threat Intelligence. • Forense Digital: Coletar e analisar artefatos digitais (memória, disco, logs) para reconstruir a linha do tempo do ataque. • Engenharia de Detecção: Criar e otimizar regras de correlação no SIEM e assinaturas de detecção (YARA, Snort/Suricata). • Automação (SOAR): Desenvolver playbooks e scripts (Python/PowerShell) para automatizar a resposta a alertas repetitivos. • Mentoria: Apoiar o desenvolvimento técnico de analistas júnior e pleno (N1/N2).

• Issue and record incoming and outgoing tax invoices • Verify basic request data, contracts, and applicable taxes (ICMS, ISS, PIS, COFINS) • Enter and validate fiscal documents in the ERP system • Support the organization and filing of fiscal documents • Perform basic billing controls and support data reconciliation • Respond to internal stakeholders' requests and clarify basic questions about tax invoices • Monitor billing deadlines and support the monthly close • Suggest operational improvements to the area's processes

• Incident Management: Lead the technical response to complex security incidents (Ransomware, APTs, Insider Threats), from detection through post-incident lessons learned (Post-Mortem). • Threat Hunting: Perform proactive threat hunting across the network and endpoints, driven by hypotheses informed by Threat Intelligence. • Digital Forensics: Collect and analyze digital artifacts (memory, disk, logs) to reconstruct the attack timeline. • Detection Engineering: Develop and tune correlation rules in the SIEM and detection signatures (YARA, Snort/Suricata). • Automation (SOAR): Build playbooks and scripts (Python/PowerShell) to automate responses to repetitive alerts. • Mentorship: Support the technical development of junior and mid-level analysts (N1/N2).
