Job summary

Codurance is seeking an Application Modernisation Principal to shape modernisation work before sales and to deliver it hands-on. Based in the UK with client-site travel, the role is senior, with no line management and a strong emphasis on architecture and delivery.

You’ll present target architectures to client CTOs, explain migration paths, and discuss how AI changes the approach. The position blends pre-sales and delivery across diverse engagements.

Qualifications

• Proven design and architecture of application modernisation with incremental migration
• Strong application development background with hands-on credibility in at least one mainstream stack such as .NET, Java or Node.js
• Cloud-native delivery experience on at least one of Azure, AWS or GCP
• Engineering discipline: automated testing, CI/CD and safe, incremental change to legacy code
• Around five years or more in a consultancy, agency or embedded client delivery environment
• Evidence of client-facing work, such as shaping scope, running discovery, or explaining a technical approach to a non-technical buyer
• Credible AI literacy: you can explain how AI tooling changes modernisation work and have used it on real code in some form
• Care about how the work is done, including testing, pairing and passing knowledge to client teams

Responsibilities

• Own the modernisation architecture story in proposals and discovery: target architecture, migration approach and risk
• Join client calls and workshops, and explain technical approaches to non-technical buyers
• Help scope work, build estimates and defend them
• Shape repeatable modernisation offers, such as an assessment-to-roadmap package or a phased migration approach
• Lead or work hands-on in live modernisation engagements: architecture, decomposition, incremental migration and re-platforming
• Advise clients on how AI tooling changes modernisation work, and say plainly where it doesn't help
• Set architecture and engineering standards and mentor engineers, without line management
• Pass knowledge to client teams as the work goes, so they can run it themselves
