Senior Software Engineer – Agentic Engineering x4

Senior Software Engineer – Agentic Engineering x4

Using AI and agentic engineering to modernise complex legacy software, and fundamentally change how engineering teams build software.

What will you actually be doing?

• Use AI coding agents to investigate, refactor and modernise legacy codebases
• Design the "engineering harness" that gives AI agents the right context, rules and constraints to work effectively
• Build repository-level instructions, agent skills, prompts and dynamic context
• Work with technologies such as Claude Code, MCP and other agentic development tools
• Establish automated testing and AI evaluation frameworks (evals) to make sure speed doesn't come at the expense of quality
• Build guardrails, sandboxes and CI/CD controls around AI-driven development

What background are we looking for?

We're looking for someone who has built a seriously strong software engineering foundation .

You’ll ideally have deep experience in C#/.NET , alongside experience working with large, complex or legacy systems.

You might have worked with:

• Claude Code, Cursor, GitHub Copilot, Codex or similar coding agents
• Agentic development or AI-assisted software engineering
• Automated testing, evals and quality frameworks
• Legacy modernisation, major refactoring or framework migrations

We're particularly interested if you've also been working with:

• Claude Code, Cursor, GitHub Copilot, Codex or similar coding agents
• Agentic development or AI-assisted software engineering
• Automated testing, evals and quality frameworks
• Legacy modernisation, major refactoring or framework migrations

Investment areas

You'll be joining during a major transformation across Technology, with significant investment in:

• Public cloud migration
• AI-enabled software engineering
