About the Role
We're looking for a Network Security Engineer to design, implement, and secure enterprise network infrastructure built on Aruba and HPE technologies. This is a hands-on role spanning both network engineering and security — you'll be responsible for building reliable network architecture while ensuring it's hardened against modern threats. If you can move fluidly between network design and security enforcement, this role is built for that.
What You'll Do
- Design, configure, and maintain enterprise network infrastructure using Aruba and HPE hardware and platforms.
- Implement and manage network security controls, including firewalls, VPNs, and access control policies.
- Monitor network traffic and security events to identify and respond to potential threats.
- Conduct network security assessments and vulnerability analysis.
- Design and enforce network segmentation, VLANs, and wireless security architecture.
- Troubleshoot network performance, connectivity, and security incidents.
- Maintain documentation for network architecture, configurations, and security policies.
- Collaborate with IT and security teams to align network infrastructure with broader security standards.
- Support compliance efforts related to network and IT security requirements.
- Stay current on emerging network security threats and Aruba/HPE platform capabilities.
What You Bring
- Strong hands-on experience with Aruba networking and security products.
- Experience with HP Enterprise (HPE) infrastructure and platforms.
- Solid background in IT security, including threat identification and mitigation.
- Strong network engineering skills, including routing, switching, and wireless architecture.
- Practical experience implementing network security best practices and controls.
- Ability to troubleshoot complex network and security issues independently.
- Strong documentation and communication skills for cross-functional collaboration.
Nice to Have
- Relevant certifications (e.g., Aruba Certified, HPE certifications, Security+, CCNA/CCNP Security).
- Experience with network access control (NAC) solutions.
- Familiarity with SIEM tools and security monitoring platforms.
- Experience supporting compliance frameworks (e.g., PCI-DSS, HIPAA, ISO 27001).
