Job Description

Senior Infrastructure Engineer - Site Reliability Engineering - Network Focus

About the Role

• We are looking for a Senior Infrastructure Engineer - Site Reliability Engineering with deep networking expertise to join the team responsible for the reliability, availability, and performance of hybrid infrastructure.
• Our environment spans on-premises VMware infrastructure, Azure, enterprise storage and backup platforms, networking, and CI/CD tooling, and we are in the middle of a multi-year migration of on-premises workloads to Azure.
• This is an SRE role with a focus in networking. Your deepest expertise will be in networking, and you will be one of the team's go-to people for network operations, perimeter security, and the network side of our cloud migration.
• Like every SRE on the team, you will also carry broader responsibilities: on-call, project work, automation, and troubleshooting across the full environment.
• Our network is managed as code and operated as one part of a larger interconnected system, and the role reflects that.

What You'll Do

• Own the day-to-day operational health of switching, routing, wireless, and perimeter infrastructure
• Design, implement, and maintain firewall policy through established change management
• Administer zero trust and remote access platforms
• Support the network side of our Azure migration: hybrid connectivity, virtual network design input, network security group and gateway implementation
• Manage network configuration through automation and configuration-as-code rather than device-by-device changes
• Serve as a primary resource when incidents have a network dimension, including ruling the network in or out quickly so the team can chase the real problem
• Maintain infrastructure health beyond the network in areas you take on: monitoring, capacity trending, performance
• Implement changes through Infrastructure as Code and CI/CD pipelines using Ansible, Terraform, and GitHub Actions
• Plan and track your work in Jira; contribute to estimates and technical feasibility discussions
• Participate in a weekly round-robin on-call rotation covering the full environment
• Remediate security findings within established timelines and support audit activities with documentation and evidence
• Follow change management procedures and keep configuration documentation accurate

What We're Looking For

• 7+ years of IT experience, including at least 2 years focused on network engineering or network operations with production ownership

Deep, demonstrable expertise in:

• Routing and switching (L2/L3, VLANs, BGP, OSPF, WAN/ISP connectivity)
• Perimeter firewalls: policy design, NAT, segmentation, and safe rule lifecycle management
• Azure networking: virtual networks, subnets, network security groups, NAT gateways, VNet integration, and hybrid connectivity
• Hands-on experience managing network infrastructure through Infrastructure as Code and automation: Ansible, Terraform, Git-based workflows. This is how we operate our network day to day.
• Comfort with open networking standards and platforms; much of our network runs on Linux-based network operating systems, and comfort at a Linux shell is expected
• Working knowledge across the broader stack, including:
• Linux and Windows Server administration
• Azure beyond networking (resource deployment basics)
• Virtualization concepts (VMware)
• Sound judgment under pressure: you know when to act, when to elevate, and how to form an opinion before you do
• Clear written communication; our change management and incident processes depend on it
• Comfort operating in an environment where many systems are business-critical, not just the obvious ones

Nice to Have

• Experience with zero trust network access platforms (Cloudflare, Microsoft Global Secure Access, or similar)
• Experience with open or disaggregated network operating systems (SONiC, VyOS, TNSR, or similar)
• Financial services or other regulated-industry experience
• Experience supporting cloud migrations from the network side
• Wireless networking experience (controller-based or cloud-managed)

A reasonable, good faith estimate of the minimum and maximum base salary for this position is $90k–$115k. This position will also include a discretionary bonus that generally will be depending on a variety of factors. Employee benefits will also be available, and details are available like Pension/401K/ Paid Vacation/ Life, Medical & Dental insurance etc.

The Company will determine the final starting salary/Pay rate in consultation with the selected candidate(s), in full compliance with applicable laws
