Job Title: Application Rationalization Lead

Location: Ottawa, ON (Remote)

Estimated Duration: 6 Months

Networking & Application Rationalization Specialist

Position Overview

We are looking for a Senior Azure Migration Engineer to support a large-scale VMware-to-Azure migration program for a major Canadian client. This is a contract opportunity where you will work closely with architects, infrastructure and network teams, and application owners to drive successful migration outcomes.

Key Responsibilities

  • Act as a trusted advisor to project teams and client stakeholders across architecture, infrastructure, and application teams.
  • Own the application rationalization scorecard — including methodology, weighting, scoring dimensions, and calibration — and produce defensible 6R treatment recommendations (rehost, replatform, refactor, rearchitect, repurchase, retire).
  • Segment the application portfolio into low, medium, and high complexity bands and define appropriate migration patterns.
  • Facilitate stakeholder interviews with application and business owners to capture business context, criticality, and integration requirements; reconcile tool-derived data with stakeholder input.
  • Produce application-to-application, application-to-service, and application-to-infrastructure dependency maps; identify dependencies not captured by discovery tools.
  • Sequence applications into migration waves based on complexity, business value, dependency clusters, and change window constraints.
  • Design and implement Azure hybrid network foundations, including hub-and-spoke and Virtual WAN topologies, ExpressRoute, VPN gateways, Network Security Groups, Azure Firewall, Private Endpoints, Private Link, and Private DNS Zones.
  • Configure and troubleshoot BGP, user-defined routes, route tables, asymmetric routing, and connectivity between on-premises and Azure environments.
  • Assess existing Azure Landing Zones against Microsoft Cloud Adoption Framework and reference architectures; identify and remediate gaps.
  • Partner with managed network service providers on firewall, routing, and DNS changes, including preparing change packages and rollback plans.
  • Use Azure Network Watcher, Connection Monitor, NSG flow logs, and traffic analytics to troubleshoot connectivity issues.
  • Mentor other engineers and contribute to runbooks and migration documentation.

Success Criteria

  • Deliver high-quality, reliable migration outcomes aligned with client expectations
  • Build strong relationships with stakeholders across technical and business teams
  • Identify opportunities to improve processes and service delivery
  • Contribute to a collaborative and high-performing team environment
  • Continuously develop technical expertise and stay current with evolving technologies

Qualifications

Azure and Migration Experience

  • 5+ years of hands-on Azure infrastructure engineering experience, including at least two large-scale migration programs
  • Proven experience migrating VMware workloads to Azure (rehost and replatform)
  • Experience with Azure Migrate and tools such as RiverMeadow, Zerto, or Carbonite/Double-Take
  • Working knowledge of Microsoft Cloud Adoption Framework and Azure Landing Zones

Networking

  • Strong expertise in Azure networking: hub-and-spoke, Virtual WAN, ExpressRoute, VPNs, NSGs, Azure Firewall, Application Gateway, Private Link, Private Endpoints, and Private DNS Zones
  • Solid understanding of networking fundamentals: TCP/IP, BGP, routing, subnetting, DNS, DHCP, NAT, and firewall design
  • Experience troubleshooting complex networking issues including routing, MTU, and connectivity challenges
  • Experience working within structured change management environments

Rationalization and Dependency Analysis

  • Experience conducting application rationalization exercises using the 6R framework
  • Ability to design and apply scoring models across complexity, business value, and technical fit
  • Experience with dependency mapping using both tooling and stakeholder input

Engineering Practice

  • Experience with Infrastructure-as-Code (Bicep and/or Terraform)
  • Scripting experience with PowerShell, Bash, and Azure CLI
  • Strong communication skills with the ability to work across technical and non-technical stakeholders
  • Post-secondary education in Computer Science, Engineering, or a related field

Nice-to-Have

  • Azure certifications (AZ-700, AZ-305, AZ-104)
  • VMware vSphere experience or VCP certification

The pay range that the employer reasonably expects to pay for this position is between CA$90.00 and CA$110.00

Our voluntary benefits offering includes medical, dental, vision and retirement benefits.
