Design and review security architecture for new and existing solutions, including cloud-native architectures (AWS, Azure, GCP), hybrid environments, microservices, and container platforms (Kubernetes/Docker) to ensure security controls, segmentation, and secure-by-design principles are applied.
Develop, update, and operationalize security policies, standards, procedures, and guidelines (access control, encryption, incident response, configuration management) aligned to frameworks such as NIST CSF, ISO 27001, CIS Controls, SOC 2, PCI DSS, GDPR, and HIPAA.
Perform identity and access management (IAM) reviews and implement secure authentication and authorization solutions (SAML, OIDC, MFA, RBAC, least privilege) for both cloud and on-premise systems.
Lead incident response and remediation efforts including triage, containment, root cause analysis, evidence collection, and post-incident reporting; coordinate with SOC, legal, PR, and business stakeholders during breach scenarios.
Configure, tune, and maintain SIEM and log aggregation solutions (Splunk, Elastic, Azure Sentinel, QRadar) to ensure detection coverage, enrichment, alert quality, and investigation playbooks are aligned to identified risk scenarios.
Assess third-party and vendor security posture through questionnaire-based assessments, evidence review, and on-site or remote audits; coordinate remediation tracking and contract-level security requirements.
Conduct secure code reviews and collaborate with application developers to remediate vulnerabilities identified via SAST, DAST, and manual code inspection; integrate security tooling into CI/CD pipelines (Jenkins, GitLab CI, GitHub Actions).
Implement and validate data protection strategies including encryption (at rest/in transit), key management, tokenization, data classification, and secure data lifecycle practices to meet privacy and compliance requirements.
Provide cloud security consulting during migrations and major platform changes: recommend secure landing zones, guardrails, network segmentation, workload hardening, and Infrastructure-as-Code (Terraform/ARM/Bicep) best practices.
Deliver board- and executive-level reporting and metrics on security posture, program maturity, KPIs, and risk reduction achievements; translate technical findings into business impact, SLAs, and remediation timelines.
Design and execute security awareness training programs and tabletop exercises for technical teams and business units to improve incident readiness and reduce human-driven risks.
Build and maintain threat models and attack surface inventories for critical business services, mapping attacker techniques to mitigations, and informing prioritized investment in controls and detection use cases.
Lead or contribute to SOC playbook development, runbooks, and automation (SOAR) for triage, enrichment, and routine response tasks to improve mean-time-to-detect and mean-time-to-respond.
Evaluate and recommend security products and managed security services (MSSP) including endpoint protection (EDR/XDR), web application firewalls (WAF), CASB, DLP, and network security appliances; support procurement and proof-of-concept testing.
Perform configuration reviews and hardening of network devices, firewalls, VPNs, proxies, and cloud-native network components to reduce misconfiguration risk and ensure appropriate logging and monitoring.
Support compliance assessments and audits (SOC 2 readiness, ISO 27001 audits, PCI DSS scans, HIPAA risk assessments), coordinate evidence collection, remediation tracking, and auditor responses.
Establish and run threat hunting initiatives leveraging threat intelligence feeds, indicators of compromise (IOCs), and advanced analytics to proactively discover attacker behavior and latent compromises.
Mentor junior security consultants and engineers, perform knowledge transfer, and help grow the security practice through documentation, standards, and repeatable engagement templates.
Prepare and present Statements of Work (SoWs), proposals, and cost estimates for consulting engagements; manage client expectations, timelines, and deliverables throughout project lifecycle.
Conduct forensic analysis on compromised endpoints and servers when needed, preserving chain-of-custody, performing artifact analysis, and delivering actionable forensic reports and legal-ready evidence.
Maintain an up-to-date understanding of emerging threats, attacker techniques, vulnerability disclosures (CVE), and security trends; translate this intelligence into pragmatic recommendations for customers and internal teams.
Coordinate cross-functional remediation projects with IT operations, engineering, product, and legal to ensure vulnerability fixes are implemented without undue disruption to business services.

Secondary Functions

Support ad-hoc security data requests and exploratory security analytics using logs, telemetry, and metadata to inform investigations and control effectiveness.
Contribute to the organization's security strategy, roadmap, and continuous improvement initiatives to mature security posture over time.
Collaborate with product, engineering, and operations teams to translate business requirements into secure technical designs and to ensure secure deployments and releases.
Participate in agile ceremonies and sprint planning to integrate security tasks (controls, code fixes, threat modeling) into regular delivery cycles.
Assist in procurement and vendor evaluation by producing technical security requirements and scoring vendor security responses.
Create repeatable engagement templates, checklists, and playbooks to accelerate future consulting projects and standardize best practices.
Support sales and pre-sales activities by preparing technical proposals, deliverable definitions, and presenting security capabilities to prospective clients.
Help maintain asset inventories, data flows, and configuration baselines that feed security monitoring and compliance programs.
