• Run vulnerability scanning and assessment programs
• Partner with IT and engineering teams to prioritize remediation based on risk
• Track remediation progress and communicate status clearly
• Implement and maintain security controls across cloud platforms such as AWS and Azure
• Help secure cloud infrastructure, applications, and services in hybrid environments
• Contribute to cloud security best practices and guardrails
• Script and automate security workflows to improve efficiency and reliability
• Support incident response and investigations when security events occur
• Contribute to documentation, architecture standards, and continuous improvement efforts

• 6+ years of experience in network, infrastructure, or security engineering roles
• Strong understanding of IP networking (TCP/IP, routing, switching, VLANs, DNS, DHCP, NAT)
• Experience with next-generation firewalls and Layer 7 traffic inspection
• Solid knowledge of cryptography concepts (TLS/SSL, VPNs, PKI, encryption)
• Familiarity with modern attack techniques (phishing, ransomware, malware, DDoS, MITM, web attacks) and defensive controls
• Experience securing cloud environments and modern infrastructure technologies (virtualization, SaaS, PaaS, containers)
• Hands‑on experience with Windows and Linux environments
• Interest and ability to code or script for automation and operational efficiency
• Strong communication skills and ability to work collaboratively in a global team
• Can combine deep technical fundamentals with curiosity, automation mindset, and a strong sense of ownership

• Work on security challenges at enterprise scale in a highly visible environment
• Broad exposure across network, cloud, endpoint, identity, and email security
• Opportunity to influence how security is designed and implemented across the organization
• Collaborative culture that values learning, ownership, and technical excellence
• Stable, in‑office team environment with strong peer partnership and knowledge sharing
