Client Solutions Principal (Application Modernisation)

About the Position

Client Solutions Principal (Application Modernisation)

Codurance is hiring a Client Solutions Principal for Application Modernisation, reporting to the Client Solutions Director. You'll spend about 40% of your time shaping modernisation work before it's sold, and 60% delivering it. It's a senior, hands-on role with no line management. You'll be based in the UK, with travel to client sites as engagements need it.

Responsibilities

Pre-sales and Solutioning

• 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

Delivery

• 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

Requirements

Must Have

• 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

Strongly Preferred

• You've supported sales in the bid process, for example by contributing to proposals, estimates, or client presentations

Nice to Have

• Data platform experience, such as lakehouse design and migration on Databricks, Fabric, or Snowflake, or an open table format stack like Delta or Iceberg
• Production applied AI experience, such as RAG pipelines, evaluation, or MCP and agentic work you can talk through in detail
• Experience in a formal pre-sales role

We Offer

• Competitive salary: £110,000.00 - £130,000.00 GBP YEAR
• Full-time employment
• Opportunity to work in London, Manchester, or Leeds, UK
• Be part of a company that values craftsmanship, real AI work, and influence in shaping modernisation work
