Azure Infrastructure Architect

Department: Azure

Employment Type: Full Time

Location: Dublin

Description

Codec is seeking an experienced Senior Azure Infrastructure Architect to join our growing Microsoft Partner practice in Dublin. This is a hands-on technical leadership role where you'll architect, price, and deliver enterprise-grade Azure infrastructure solutions for our diverse client base. You'll be expected to roll up your sleeves and implement the solutions you design, not simply hand over specifications to others.

Working at the intersection of technical expertise and customer consultancy, you'll apply Well-Architected Framework principles, Cloud Adoption Framework methodologies, and Azure Landing Zone accelerators to solve complex infrastructure challenges. You'll manage multiple concurrent projects, delegate effectively to engineering teams, and maintain the technical depth required to guide implementations from initial discovery through to production deployment. This role demands someone who thrives in a Microsoft Partner environment, where the pace is fast, the technical challenges are varied, and customer success is paramount.

As a senior member of our technical team, you'll balance deep architectural work with customer-facing responsibilities. You'll lead technical workshops, conduct architecture reviews, produce detailed costings and proposals, and build lasting relationships with enterprise clients. This is an opportunity for a technically accomplished professional who wants to shape infrastructure strategy whilst remaining firmly grounded in hands-on delivery.

This is a hybrid position based at our Dublin office, with flexible remote working arrangements that support work-life balance. Regular travel to customer offices across Ireland is a core expectation of the role, with occasional travel to UK client sites. Rather than viewing travel as a burden, we see these on-site engagements as invaluable opportunities to build strong client relationships, understand business context firsthand, and deliver the consultative experience that sets our practice apart. You'll typically spend 2–3 days per week at customer locations or in our Dublin office, with the remainder worked flexibly from home.
