Azure Infrastructure Senior Engineer; NI

Overview

Department: Azure

Employment Type: Full Time

Location: Belfast

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.

• 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 Power Shell-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 Dev Ops Pipelines and Git Hub 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

• 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

• Automation-first mindset - instinctively reach for code and pipelines rather than manual processes
• Ownership mentality - you see tasks through to completion and take pride in the quality of what you deliver
• Delivery focus - you understand the balance between engineering…
