Job summary

Codurance in the UK is seeking an Application Modernisation Principal for Client Solutions. The role is senior, hands-on with no line management and requires travel to client sites as engagements need it.

You will design target architectures for modernising aging estates, explain approaches to client CTOs, and shape offers that balance architecture, AI insights and risk, while keeping business operations uninterrupted.

Qualifications

• Proven design and architecture of application modernisation: moving legacy or monolithic systems to modern architectures in increments while the business keeps running
• A 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
