Dear Hiring Manager,

I am writing to express my interest in the Senior Network and Security Engineer position. With over eight years of experience in enterprise network security and infrastructure, I bring deep, hands-on expertise across multi-vendor firewall platforms, combined with a strong core networking background.

In my current role as a Senior Network and Security Engineer at LRQA Nettitude, and previously within MSP/MSSP environments, I work daily across all four major enterprise firewall vendors, such as Palo Alto, Check Point, Fortinet, and Cisco Firepower. I design, implement, upgrade, and support high-availability firewall solutions, manage centralized platforms such as Panorama and FortiManager, and lead complex VPN, SD-WAN, and security policy deployments. Operating in MSP/MSSP environments has strengthened my ability to manage multiple enterprise customers simultaneously, act as a Tier 3 escalation point, and deliver secure solutions under strict SLAs and change governance frameworks.

My technical foundation is rooted in core networking. I have extensive experience with Cisco and Juniper routing and switching platforms, working with technologies including BGP, OSPF, MPLS, VRF, and L3VPN. This networking depth allows me to design firewall architectures that are not only secure but fully aligned with resilient, scalable network design principles. In addition, I work daily with Cisco Meraki environments, supporting cloud-managed security and switching infrastructures across distributed enterprise sites.

Throughout my career, I have led end-to-end project delivery — from requirements gathering and architectural design through implementation, risk assessment, and post-deployment optimisation. I regularly collaborate with architects, NOC teams, and senior stakeholders to modernise infrastructure while maintaining operational stability. I also mentor engineers and contribute to building collective technical capability within the team.

I am particularly drawn to this opportunity because it aligns closely with my background in enterprise firewall leadership, multi-vendor expertise, and large-scale network security design. I am confident that my ability to operate across platforms, combined with my strong routing and switching foundation and MSP experience, would allow me to contribute immediate value to your team.

I would welcome the opportunity to discuss how my experience aligns with your requirements.
