Join IG Group’s newly formed Service Modernisation & AI team as a pioneer of AI-first development practices in financial services. You’llmodernise and simplify critical legacy services using cutting-edgeAI tooling whiledemonstratingwhat’s possible when AI is deeply integrated throughout the development lifecycle.

This is a hands‑on engineering role focused on delivery. You’llship modernised services in fast cycles while showing other engineers how AI transforms productivity and code quality.

You will be part of a small team to start, 5-6 senior engineers and an embedded architect, and scale with contractors as needed based on the pipeline and opportunities. You will be hands‑on in code using the latest in AI engineering practices.

• Use AI to analyse codebases, understand dependencies, and extract clean APIs

• Work on high-impact legacy services that block divisional delivery speed

• Implement strangler fig patterns and other proven migration approaches

• Deliver modernised services with comprehensive tests, documentation, and multi‑instance deployment capabilities

• Complete service modernisations in fast cycles with monthly milestones

• Use AI to accelerate every phase: analysis, refactoring, testing, documentation

• Hand off modernised services to Platform Services or divisions with clear ownership

• Demonstrate measurable improvements: faster APIs, better performance, higher reliability

• Implement Model Context Protocol (MCP) servers for service discovery, dependency mapping, and architecture compliance

• Create AI‑assisted CI/CD pipelines with automated code review, security scanning, and test generation

• Build automation using Claude Code, Git Hub Copilot, and LLM APIs

• Develop reusable AI tooling that other engineers can adopt

• Use AI for all coding tasks: refactoring, test creation, documentation, debugging

• Achieve measurable and significant productivity improvements through AI integration

• Document patterns and share learnings through your work

• Train teams during service handoffs on AI‑enabled workflows you’ve built

• Demonstrate when to use AI vs when human judgement is critical

• 8+ years software engineering with Java backend expertise

• Experience modernising production systems at scale

• Strong API design and microservices architecture knowledge

• Understanding of strangler fig patterns, service decomposition, and legacy migration strategies

• Hands‑on experience building with Model Context Protocol (MCP)

• Demonstrated use of Claude Code, Git Hub Copilot, or similar AI development tools in production work

• Experience implementing AI in CI/CD pipelines (code review, testing, security scanning)

• Built agentic AI solutions or AI‑powered automation tools

• Understanding of prompt engineering, model selection, and LLM capabilities/limitations

• Achieved measurable productivity improvements using AI in development

• Implemented AI‑assisted refactoring, test generation, or documentation at scale

• Experience with AI code analysis and automated remediation

• Track record of shipping production systems built with AI assistance

• Delivery‑focused:
  Ship working modernised services, don’t just…
