Job Description
So, who are we?
IG has been at the centre of retail trading and investment since 1974, when we helped create the market for financial spread betting. Today, we're a FTSE100 fintech operating across five continents, serving over 700,000 clients and handling billions in transactions - built on decades of scale, trust and proof. We didn't pivot to innovation; it's how we've always operated. What that means for the people who work here is real: genuinely complex problems to solve, the technology and resources to tackle them properly, and the kind of scope that’s rare in established businesses. The bar is high - bring a curious and forward-thinking mindset and we'll give you the platform to define what comes next. Join us at IG – the future gets built here.

This is a hands-on engineering role focused on delivery. You'll ship modernised services in fast cycles while showing other engineers how AI transforms productivity and code quality.
Your role in the Team's Success
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.

- 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
-
Ship Results Quickly
- 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
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
AI Implementation & Automation (50%)
-
Build AI-Powered Development Infrastructure
- 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, GitHub Copilot, and LLM APIs
- Develop reusable AI tooling that other engineers can adopt
-
Demonstrate AI-First Development
- 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
What You'll Need For This Role
Backend Engineering
