problems to resolution.\nKey Responsibilities\nAzure Infrastructure & Platform Engineering\nDesign, implement, and operate enterprise-scale Azure infrastructure across IaaS and PaaS services.\nOwn technical architecture and engineering decisions for complex Azure environments.\nDesign highly available, scalable, secure, and resilient Azure solutions.\nLead infrastructure modernization, cloud migration, and platform transformation initiatives.\nEstablish Azure infrastructure standards, reference architectures, and engineering best practices.\nEvaluate Azure services and determine appropriate technology choices based on business and technical requirements.\nDrive continuous improvement of platform reliability, scalability, performance, security, and operational efficiency.\nAzure IaaS\nStrong hands-on expertise with:\nAzure Virtual Machines and VM Scale Sets\nAvailability Zones and Availability Sets\nManaged Disks and Azure Storage\nAzure Virtual Network,

Container Instances / container platforms\nAzure API Management\nAzure Service Bus\nEvent Grid\nAzure Key Vault\nAzure SQL / managed database services\nAzure Cache and other managed platform services\nAzure Storage services\nThe candidate should understand when to use managed PaaS services versus IaaS, including the operational, security, scalability, availability, and cost trade-offs.\nNetworking\nDeep understanding of Azure networking is highly important.\nResponsibilities include:\nDesigning hub-and-spoke and enterprise-scale network architectures\nVNet peering and Virtual WAN concepts\nPrivate Link / Private Endpoint architectures\nDNS architecture and troubleshooting\nExpressRoute and hybrid connectivity\nVPN architecture\nAzure Firewall and network security controls\nRouting, UDRs, NSGs and traffic flows\nLoad balancing and application delivery\nNetwork troubleshooting using packet-level and platform telemetry\nIntegration of Azure with on-premises and other cloud environments\nSecurity & Identity\nDesign Azure environments following security-by-design principles.\nStrong understanding of Microsoft Entra ID, RBAC, Managed Identity and service principals.\nImplement least-privilege access models.\nDesign secure network segmentation and private connectivity.\nWork with security teams on Defender for Cloud, security posture, vulnerability management, and incident response.\nImplement secrets, certificates, and key management using Azure Key Vault.\nUnderstand Azure Policy, governance, compliance, and resource controls.\nInfrastructure as Code & Automation\nStrong hands-on experience with infrastructure automation is expected.\nAzure Bicep / ARM Templates and/or Terraform\nPowerShell and/or Azure CLI\nGit-based infrastructure management\nCI/CD automation\nAutomated provisioning and configuration\nInfrastructure testing and validation\nPolicy-as-code and governance automation\nAutomated remediation and operational tooling\nThe candidate should be able to write and review production-quality automation, not merely consume existing scripts.\nReliability, Resiliency & Disaster Recovery\nDesign solutions for high availability and fault tolerance.\nDevelop regional and multi-region architectures where required.\nDefine and implement RTO/RPO strategies.\nDesign backup, restore, and disaster recovery solutions.\nParticipate in DR testing and failure-recovery exercises.\nDevelop self-healing and automated remediation capabilities.\nPerform capacity planning and resilience assessments.\nLead technical root-cause analysis for major production incidents.\nMicrosoft's mission-critical Azure guidance specifically highlights patterns such as multi-region/Availability Zone resilience, self-healing, scale-out, observability, and regular recovery testing. (Microsoft Learn)\nObservability & Operations\nDesign comprehensive Azure monitoring and observability solutions.\nStrong experience with Azure Monitor, Log Analytics, Application Insights and alerting.\nDevelop operational dashboards and health models.\nDefine SLI/SLO and operational metrics where appropriate.\nTroubleshoot complex performance, availability, networking, and infrastructure issues.\nLead technical RCA for Sev-1/Sev-2 incidents.\nIdentify systemic problems and implement permanent engineering solutions rather than tactical fixes.\nPerformance & Cost Optimization\nPerform Azure capacity and performance analysis.\nIdentify infrastructure bottlenecks and scalability constraints.\nOptimize compute, storage, networking, and PaaS consumption.\nDrive Azure cost optimization without compromising reliability or security.\nUse Azure Advisor and platform telemetry to identify optimization opportunities.\nTechnical Leadership\nAct as a technical authority for Azure infrastructure and platform engineering.\nMentor senior engineers and help raise engineering standards.\nReview architecture and technical designs.\nChallenge design assumptions and identify technical risks.\nLead complex engineering initiatives from design through implementation.\nCollaborate with application, security, networking, SRE, DevOps, and architecture teams.\nProvide technical leadership during major incidents and high-impact infrastructure changes.\nInfluence engineering decisions across teams without relying on formal management authority.\nGood to Have\nAzure Solutions Architect Expert certification.\nAzure Administrator Associate certification.\nAzure Network Engineer Associate certification.\nExperience with AKS and container platforms.\nExperience with Azure Landing Zones / Enterprise Scale architecture.\nExperience with Azure Policy and governance.\nExperience with DevOps / CI/CD platforms.\nExperience with GitHub Actions, Azure DevOps or similar.\nExperience with FinOps / Azure cost optimization.\nExperience with SRE practices.\nExperience operating large-scale distributed systems.\nWhat We Are Looking For\nWe are looking for an engineer who demonstrates Principal-level technical depth, not simply breadth of Azure certifications.\nThe successful candidate should be able to:\nTake an ambiguous infrastructure problem and develop the technical solution.\nDesign an Azure architecture and explain the trade-offs.\nGo deep into networking, compute, storage, identity, security, and platform services.\nTroubleshoot complex production failures end-to-end.\nAutomate repetitive infrastructure and operational tasks.\nReview and improve existing architectures.\nDesign for reliability, security, scalability, performance, and cost.\nLead technical discussions with architects, engineers, and senior stakeholders.\nMentor other engineers through technical influence.\nRemain hands-on with technology rather than operating purely at an architectural or management level.\nIdeal Candidate Profile\nThe strongest candidates are likely to come from backgrounds such as:\nPrincipal Cloud Engineer\nPrincipal Azure Engineer\nPrincipal Infrastructure Engineer\nSenior/Lead Azure Infrastructure Engineer\nCloud Platform Engineer\nSenior Cloud Architect with strong hands-on engineering experience\nPrincipal DevOps / SRE Engineer with deep Azure infrastructure expertise\nAzure Platform Engineer\nCandidates whose experience is primarily Azure administration, basic VM provisioning, application deployment, or certification-driven cloud architecture without deep production troubleshooting would not be a strong fit.\nSeniority Indicators\nThe candidate should demonstrate evidence of:\nArchitecture → Engineering → Automation → Operations → Troubleshooting → Technical Leadership\nrather than only:\nCertification → Service Knowledge → Administration\nThe role is expected to be approximately 70% technical/engineering and 30% technical leadership/architecture, with the exact balance depending on the project and organizational requirements.","description_format":"text","description_chars":9612,"description_truncated":false,"requirements":{"experience_years_min":12,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"India","iso":"IN","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Billing
