Senior network security engineer
Job Details
Dear Hiring Manager,
I am writing to apply for the Network, System, and Cybersecurity Engineer position within your organization. I bring over eleven years of professional experience in network engineering, systems administration, and cybersecurity, with a strong track record of supporting enterprise-scale infrastructures through both on-site and remote engagements.
I currently work as a System Engineer – Network and Security at Royal Technology Solutions in Abu Dhabi, where I support secure, high-availability environments for business-critical operations. Prior to this, I served as a Senior Network, System, and Cybersecurity Engineer at Tech Mahindra/Fairfax Solutions, supporting nationwide infrastructure across more than 400 locations. My responsibilities included designing and securing LAN, WAN, VPN, and data center environments, executing disaster recovery plans, and leading incident response and vulnerability management initiatives.
Throughout my career, I have worked extensively in hybrid delivery models, providing hands-on on-site implementation as well as remote monitoring, troubleshooting, optimization, and security operations. I am comfortable collaborating with distributed teams, vendors, and stakeholders across time zones while maintaining high service availability and security standards.
I have deep experience with multi-vendor technologies including Cisco, Huawei, Palo Alto, Fortinet, Juniper, Dell, F5, Ruckus, and cloud-related security models. My work has aligned closely with international best practices, including ISO 27001, NIST frameworks, and incident response methodologies. I have also contributed to large-scale, high-impact projects such as national ERP systems, government data centers, and critical infrastructure environments.
In addition to technical expertise, I offer forceful communication and leadership skills. I have mentored engineers, delivered technical training, prepared detailed design and handover documentation, and worked closely with management to align IT security strategies with business objectives. I hold a bachelor's degree in electrical and computer engineering and multiple globally recognized certifications, including CISSP, AWS Security, Cisco, Huawei, Fortinet, OPSWAT, and EC-Council.
I am eager to contribute my experience to organization that values secure, resilient, and well-architected systems. I would welcome the opportunity to discuss how my skills and international experience can add value to your team.
Thank you for your time and consideration. I look forward to the opportunity to speak with you.
Sincerely,
Senay Ketsela
