About the Role

McKesson is seeking a Senior Network Security Engineer to lead the design, implementation, and governance of secure enterprise network infrastructure across cloud, data center, and hybrid environments. This role will drive the evolution of McKesson’s network security architecture through Zero Trust principles, segmentation strategies, secure access technologies, and advanced threat detection capabilities. The ideal candidate combines strong network engineering expertise with a modern security mindset and the ability to build scalable, resilient, and compliant infrastructure that supports critical business operations.

What You'll Do

Lead the design and implementation of secure network architectures using Zero Trust principles.

Develop and maintain network segmentation and micro-segmentation strategies to reduce attack surface and improve security posture.

Perform security architecture reviews and provide technical recommendations for infrastructure modernization initiatives.

Manage and optimize Palo Alto firewalls, network security policies, and perimeter defense controls.

Support Zscaler, Secure Internet Gateway, web proxy, and HPE EdgeConnect technologies across enterprise environments.

Design and support secure remote-access solutions including Zero Trust Network Access (ZTNA), VPN, and Network Access Control (NAC).

Monitor and analyze network traffic using IDS/IPS technologies, threat detection platforms, and security analytics tools.

Partner with cloud, infrastructure, and platform engineering teams to ensure secure, scalable, and compliant network services.

Minimum Requirements

7+ years of progressive experience in network security engineering, cybersecurity engineering, infrastructure engineering, or related technical roles.

Bachelor's degree or equivalent combination of education and experience.

Hands-on experience designing and supporting enterprise network security architectures.

Experience administering enterprise firewall platforms, including Palo Alto Networks.

Experience with Zero Trust Architecture, network segmentation, and secure network design.

Experience supporting VPN, ZTNA, NAC, or related identity-based network access technologies.

Experience with IDS/IPS technologies, network traffic analysis, and security monitoring.

Ability to communicate technical concepts and influence security decisions across multiple teams.

Preferred Skills

Experience with Zscaler, Secure Internet Gateway technologies, and web proxy solutions.

Experience supporting HPE Aruba EdgeConnect or SD-WAN environments.

Knowledge of micro-segmentation technologies in multi-cloud or hybrid environments.

Experience securing cloud networking environments within AWS, Azure, or GCP.

Knowledge of infrastructure automation tools such as Terraform, Ansible, or Puppet.

Experience with Kubernetes, container security, and modern platform engineering practices.

Experience working in healthcare or other highly regulated industries.

Security certifications such as CISSP, PCNSE, CCNP Security, CCIE Security, Zscaler certifications, or equivalent.

Travel, Work Environment & Physical Requirements

Hybrid or remote work arrangement based on business needs.

Limited travel may be required for team collaboration, strategic planning sessions, or project implementation activities.

Ability to work on a computer for extended periods and participate in virtual or in-person meetings.

We are proud to offer a competitive compensation package at McKesson as part of our Total Rewards. This is determined by several factors, including performance, experience and skills, equity, regular job market evaluations, and geographical markets.
