From the CTO: “We're embarking on a major modernisation programme for one of our core business platforms. An internal proof of concept has already demonstrated what's possible using AI-assisted engineering. Your role will be to take that concept into production, creating a scalable engineering approach that accelerates software delivery while maintaining high standards of quality, security and maintainability.”
This is about far more than migrating applications. It's about redefining how engineering teams build software utilising AI tools particularly Codex.
What You'll Be Doing
- Lead AI-assisted software engineering
- Use Codex and modern AI development tooling to dramatically accelerate software analysis, refactoring, testing and modernisation.
- Develop practical engineering workflows that combine AI with strong software engineering discipline.
- Champion AI-first development practices across the wider engineering team.
- Coach engineers on how to effectively use AI tooling to increase productivity without compromising quality.
- Help establish repeatable engineering standards for AI-assisted development across future programmes.
- Lead the modernisation of a large legacy monolithic application into a modern Azure-based architecture.
- Design APIs and middle-tier services consumed by external React engineering teams.
- Drive engineering excellence
To be considered, we're looking for an experienced Lead Engineer | Senior Engineer with a passion and expertise in AI First engineering.
You'll bring:
- Expertise embracing and driving AI-assisted engineering using OpenAI Codex
- Strong experience building enterprise backend applications using C# / .NET
- Experience modernising legacy applications and monolithic platforms
- Azure cloud experience
- API-first architecture experience
- Experience designing scalable backend services
- A passion for software craftsmanship and engineering quality
