What You'll Do

As a Senior Infrastructure Security Engineer, your primary focus will be safeguarding our cloud platforms, networks, and underlying systems by:

• Managing configurations, encryption, and access controls in AWS, ensuring cloud monitoring and compliance with frameworks like PCI DSS and SOC 2.

• Implementing Infrastructure-as-Code (IaC) best practices to efficiently provision and secure cloud resources.

• Configure and maintain firewalls, web application firewalls (WAF), host intrusion detection systems (HIDS), network intrusion detection/prevention systems (NIDS/NIPS), and VPNs.

• Design architecture concepts that incorporate network segmentation, zero-trust principles, and other best practices to minimize attack surfaces.

• Apply hardening strategies for Kubernetes clusters, operating systems, and containerized environments.

• Integrate data leakage prevention (DLP) controls to safeguard sensitive information across systems.

• Lead vulnerability scanning processes using SIEM, endpoint detection, and cloud security platforms; track and remediate findings with relevant teams.

• Collaborate with Infrastructure and DevOps to ensure continuous security across CI/CD pipelines, including container image scanning and automated patching.

• Develop, refine, and implement incident response playbooks for infrastructure-related threats.

• Monitor systems, investigate potential security events, and produce post-incident reports with actionable insights.

• Develop scripts (Python, Bash, etc.) to automate repetitive security tasks and streamline threat detection.

• Evaluate and deploy AI-powered security solutions that enhance operational efficiency and reduce mean time to detect/respond.

• Conduct infrastructure-focused security training for internal teams, promoting a culture of secure operations.

• Collaborate with risk, fraud, and compliance teams to align infrastructure security controls with PCI DSS, SOC 2, ISO 27001, or other relevant standards.

What We Look For

• 5+ years in cybersecurity roles, emphasizing infrastructure security, cloud security (especially in AWS), and network security.
