Senior Network Engineer

Quality Assurance Process and Documentation

The Role

We are seeking a Senior Network Engineer with senior engineer or architect level experience to lead quality assurance, runbook ownership, and process excellence for a large scale, multi vendor network deployment program.

This is not a hands on configuration role. Instead, this position is ideal for a seasoned network professional who has spent years deploying circuits, firewalls, or routing and switching infrastructure and now applies that experience through oversight, quality gates, documentation ownership, and disciplined process execution.

Your impact will be measured by how effectively you prevent defects, improve consistency, and ensure that every device shipped meets documented standards.

What You Will Do

Quality Assurance and Oversight

  • Perform pre shipment quality assurance reviews of network device configurations across Fortinet, Juniper, and Cradlepoint platforms
  • Serve as the final technical review and quality gate before devices are released for shipment
  • Validate configurations against detailed multi step runbooks and standards to identify errors, omissions, or deviations
  • Provide real time oversight and coaching to engineers during staging and build activities without directly performing configurations

Runbook and Process Ownership

  • Review, validate, and continuously improve technical runbooks covering the full device build lifecycle
  • Ensure runbooks accurately reflect the current thirty five step configuration standard
  • Update documentation immediately when issues are discovered so lessons learned are captured and reused
  • Drive strong change control discipline by ensuring deviations are documented, reviewed, and approved

Technical Documentation and Knowledge Management

  • Develop and maintain clear technical documentation that engineers can follow without prior project context
  • Document the ecosystem of systems involved in the build process, including sixteen source systems and approximately twenty five required data points per device
  • Create templates, checklists, and reference materials that reduce risk and improve consistency in a highly manual environment

Customer and Cross Functional Engagement

  • Communicate quality assurance status, readiness, and outcomes to internal and customer stakeholders
  • Provide written and verbal updates on findings, exceptions, and resolutions
  • Partner with project managers, logistics teams, and senior engineers throughout the device build and shipping lifecycle

What We Are Looking For

We are intentionally not limiting this role to a specific vendor certification or technology stack. We are looking for experienced network professionals who bring depth in at least one of the following areas.

Required Experience

  • Demonstrated depth in one or more of the following:
  • Runbook creation, ownership, and execution in real deployment environments
  • Technical documentation that engineers can reliably execute
  • Quality assurance or quality process ownership in a network engineering context
  • Experience with at least one of the following deployment backgrounds:
  • Large scale circuit rollouts including cellular, DIA, or WAN
  • Enterprise firewall deployments across multiple sites
  • Enterprise routing and switching deployments
  • Eight or more years of progressive network engineering experience with senior engineer or architect level exposure
  • Strong foundational understanding of networking including circuits, routing, switching, VLAN design, and centralized management platforms
  • Strong change control mindset with an emphasis on process discipline and quality outcomes
  • Excellent written communication skills and customer facing professionalism

Preferred Experience

  • Experience with FortiManager or similar centralized network management platforms
  • Familiarity with Fortinet, Juniper, or Cradlepoint environments
  • Experience supporting large scale, repeatable network deployment programs
