Network/Infrastructure Security Manager

Glocomms is partnered with a leading high-performance computing (HPC) infrastructure firm to identify a Manager of Infrastructure & Network Security responsible for leading and scaling security efforts across large-scale, GPU-intensive environments. This organization operates at the intersection of advanced compute, cloud infrastructure, and modern data center design, supporting highly distributed, performance-critical workloads. This role will own the development and execution of a comprehensive infrastructure security program, with a strong focus on network architecture, attack surface reduction, and operational resilience, while managing and mentoring a growing technical team.

Primary Responsibilities

• Lead the design and implementation of secure network architecture across HPC, cloud, and data center environments, including GPU clusters
• Manage and evolve the organization's infrastructure security program aligned with business objectives and risk tolerance
• Oversee attack surface management initiatives, including exposure tracking, vulnerability identification, and remediation prioritization
• Implement and enforce network security controls such as firewalls, IDS/IPS, VPNs, secure web gateways, and Zero Trust Network Access (ZTNA)
• Drive network segmentation and micro-segmentation strategies to prevent lateral movement and enable rapid threat containment
• Establish continuous monitoring and visibility across server, network device, and edge environments
• Lead vulnerability scanning and infrastructure hardening efforts using industry frameworks (CIS Benchmarks, NIST, DISA STIGs)
• Partner cross-functionally with IT operations, engineering, and leadership teams to align on security policies, operational resilience, and workload prioritization
• Translate technical risks into clear business context and deliver executive-level reporting on security posture and emerging threats
• Manage, mentor, and develop a team of security engineers while balancing competing priorities in a fast-paced environment

Key Qualifications

• 7-10 years of experience in infrastructure or network security, including prior leadership or management experience
• Strong expertise in network architecture and security, including segmentation, micro-segmentation, and edge security
• Hands-on experience with security tools and controls such as firewalls, IDS/IPS, VPNs, secure web gateways, and ZTNA
• Deep knowledge of vulnerability management, including scanning, risk prioritization, and remediation workflows
• Experience with attack surface management and exposure management in distributed or HPC environments
• Familiarity with security frameworks such as CIS Benchmarks, NIST, and DISA STIGs
• Proven ability to develop security roadmaps and manage programs end-to-end
• Strong communication skills with the ability to present technical risk to both technical and non-technical stakeholders
• Demonstrated experience building and developing technical teams in a high-growth or evolving environment
• Ability to operate effectively in a fast-paced setting while managing competing priorities

This opportunity offers the opportunity to lead and shape security strategy within a cutting-edge HPC infrastructure environment.
