Azure Infrastructure Senior Engineer

Department: Azure

Employment Type: Full Time

Location: Dublin

Description

Codec is looking for a Senior Azure Infrastructure Engineer who thrives on turning architectural vision into production-ready reality. This is a hands-on implementation role for someone who takes genuine pride in building Azure infrastructure solutions the right way: automated, tested, version-controlled, and secure.

You'll work closely with our Cloud Solution Architects to bring their designs to life, implementing enterprise-grade infrastructure that follows Microsoft's Well-Architected Framework, Cloud Adoption Framework, and Azure Landing Zone patterns. This isn't about ticking boxes-it's about crafting robust, repeatable solutions that stand up to real-world enterprise demands. You'll collaborate with Project Managers to ensure delivery stays on track across multiple concurrent customer engagements, balancing technical excellence with practical delivery discipline.

As part of a Microsoft Partner organisation, you'll gain exposure to varied enterprise environments and challenging technical problems. This is an opportunity for a strong engineer who wants to deepen their Azure expertise whilst working on meaningful projects that directly impact how businesses run their critical infrastructure. If you care about Infrastructure as Code done properly, enjoy the satisfaction of seeing automated pipelines deploy complex environments flawlessly, and want to work somewhere that values engineering craft, this role will suit you well.

This is a hybrid role based from our Dublin office, with flexible remote working arrangements. You'll have the flexibility to balance office and remote work in a way that supports both collaboration and focused implementation time.

Occasional travel to enterprise customer sites may be required to support the Cloud Solution Architect during on-site engagements. Whilst the Architect leads customer interactions, these visits provide valuable exposure to enterprise environments and broaden your understanding of how solutions operate in different organisational contexts.

Key Responsibilities

Implement Azure infrastructure solutions based on designs and architectural patterns provided by Cloud Solution Architects, ensuring alignment with Microsoft best practices and customer requirements
Build, maintain, and continuously improve Infrastructure as Code using Terraform, Bicep, and PowerShell-writing modular, reusable, and testable code that can be confidently deployed across multiple environments
Design and manage CI/CD pipelines for infrastructure deployment using Azure DevOps Pipelines and GitHub Actions, incorporating appropriate gates, approvals, and quality checks
Implement automated testing for IaC deployments and ensure robust secret management practices using Azure Key Vault and secure pipeline variable handling
Configure and manage Microsoft Entra ID components including conditional access policies, identity governance frameworks, Privileged Identity Management (PIM), and SSO configurations
Implement and configure the Microsoft Defender suite (Defender for Cloud, Defender for Endpoint, Defender for Identity) as integral components of customer solution delivery
Deploy and configure core Azure infrastructure services including Virtual Networks, ExpressRoute/VPN connectivity, Azure Firewall, Network Security Groups, Load Balancers, Virtual Machines, Storage accounts, and Compute services
Collaborate closely with Project Managers to ensure tasks are properly tracked, effort is estimated accurately, and work is delivered on schedule across multiple concurrent projects
Work alongside the Cloud Solution Architect during customer engagements, providing technical input and supporting architecture discussions when required
Produce and maintain clear, comprehensive technical documentation and runbooks for implemented solutions, enabling smooth handover and ongoing support
Set up monitoring, alerting, and observability using Azure Monitor, Log Analytics, Application Insights, and related tooling to ensure solutions remain healthy and performant
Informally mentor and support junior and mid-level engineers-sharing knowledge through code reviews, pair programming, and helping raise overall team engineering standards
Contribute to internal automation tooling, reusable templates, and standardised modules that improve delivery efficiency and consistency across the team
Stay current with Azure platform updates, new service capabilities, and evolving best practices-proactively suggesting improvements to existing customer environments where appropriate
Cost up solutions using the Azure pricing calculator with options for PAYG, Reserved Instances and Savings Plan

Good working knowledge of Azure core infrastructure services: Virtual Networks, VPN/ExpressRoute, Azure Firewall, Network Security Groups, Load Balancers, Virtual Machines, Storage accounts, and Compute services
Working knowledge of Microsoft Entra ID: conditional access policies, identity management, Privileged Identity Management (PIM), and SSO configuration
Working knowledge of the Microsoft Defender suite (Defender for Cloud, Defender for Endpoint, Defender for Identity) and how it integrates into Azure infrastructure solutions
Familiarity with Microsoft Well-Architected Framework (WAF) and Cloud Adoption Framework (CAF) principles and how they guide infrastructure design decisions
Strong collaboration skills - comfortable working closely with Architects and Project Managers in a delivery-focused, consultancy environment
Ability to manage own workload effectively across multiple concurrent projects, estimate effort accurately, and flag risks or blockers early
Experience working within a Microsoft Partner or consultancy environment is strongly advantageous

Experience with Azure Kubernetes Service (AKS) or containerised workloads and their supporting infrastructure
Familiarity with Azure Migrate, Azure Site Recovery, or other migration tooling for lift-and-shift or cloud-native migrations
