This experience will allow me to bring valuable domain knowledge and automation expertise to IBM. Additionally, I've developed a knack for diagnosing and resolving complex network issues, which I believe would make me an asset to your team.

I'm particularly excited about the opportunity to work on IBM's cloud networking projects, as I believe that the future of networking lies in the cloud. I'm confident that my experience and passion for networking will enable me to contribute meaningfully to these projects and help drive IBM's continued success in the field of network engineering.

I still remember the first script I wrote to automate a routine networking task. It was a simple Perl script, but seeing it run successfully was a defining moment in my career. Since then, I've been on a mission to automate away the toil in network operations. When I came across the Senior Network Automation Engineer role at Arista, I was immediately drawn to it.

At Resume Worded, I built an automation framework using Python and Nornir that reduced provisioning times for new devices by 80%. I also developed a gitops workflow using GitLab CI/CD that enables us to manage our network infrastructure as code. These initiatives have freed up our team to focus on more strategic projects. In my previous role at RW Tech Company, I designed and implemented a zero-touch provisioning system for our data center network using DHCP, iPXE, and Ansible.

I'm excited about the opportunity to bring my automation expertise to Arista. I'm particularly impressed by Arista's commitment to open, programmable networks and would relish the chance to contribute to tools like CloudVision and EOS.

I thrive in environments where I can continually learn and push the boundaries of what's possible with network automation. I would be thrilled to discuss further how I can help drive automation initiatives at Arista.

Network Automation Engineer Cover Letter Example

Dear Liam,

My journey into networking began in a college dorm room, huddled over a Cisco router and determined to master the art of subnetting. That determination has fueled my career ever since. When I discovered Cumulus Networks and your focus on open, scalable, and automated networking solutions, I knew I had to be part of it. Your mission to simplify networking through automation aligns perfectly with my own professional goals.

Throughout my career, I've sought out opportunities to leverage automation to drive efficiency and agility. As a Network Engineer at Resume Networks, I developed a Python-based tool to automate config backups and updates across 1000+ Cisco switches, reducing provisioning time by 85%. I also led an initiative to implement network infrastructure as code using Ansible, enabling us to manage our entire data center network through version-controlled playbooks. This improved consistency and reduced human error significantly.

At Worded Widgets, I designed and deployed a containerized microservices architecture on Kubernetes, automated with GitOps workflows. This experience, combined with my deep knowledge of Cisco ACI and Nexus platforms, has prepared me to dive headfirst into driving network automation initiatives at Cumulus.

Thank you for your consideration. I'm excited about the potential to bring my automation expertise and passion for innovation to the Cumulus team, and I look forward to exploring this opportunity further.
