Your team

The Lifecycle team is a product-aligned, customer-first engineering team owning onboarding, activation, and engagement experiences across IG's platform. We build and support the critical first-mile customer journey and ongoing engagement features - with an obsessive focus on reducing friction, improving conversion, and driving engineering excellence to ensure our systems are reliable, performant, and easy to change.

Your role in the Team's Success

Your primary responsibility will be to contribute the development of complex web applications for our award-winning trading platforms — and take ownership of how they're built, deployed, and served to clients.

You'll build performant web solutions, while also understanding the infrastructure that delivers them — from CI/CD pipelines through to CDN configuration and cloud deployments. You'll work as a hands-on practitioner who leads by example while mentoring others in the team. You'll leverage AI-assisted development tools as a core part of your workflow — we expect engineers to actively embrace AI to multiply their impact. Think and act like an owner — your code directly enable traders to seize market opportunities

What you'll do

  • Contribute to the development of complex web features for our award-winning trading platforms, ensuring optimal performance, accessibility, and user experience

  • Understand and maintain cloud infrastructure for web deployments (e.g. static site hosting on AWS (CloudFront, S3, Route 53)

  • Contribute to the design and optimise CI/CD pipelines for web applications, improving build speed, deployment reliability, and release confidence Implement and tune HTTP caching strategies, CDN configurations, and performance optimisations that deliver lightning-fast experiences to traders worldwide

  • Collaborate with cross-functional teams including backend engineers, designers, and product managers to deliver features that drive business growth and champion the client

  • Actively participate in product development, from requirements discussions to seeing customers using your software in production

  • Mentor junior developers and contribute to technical decision-making that shapes our web development and deployment standards – raising the bar across the team Own end-to-end delivery of features – from technical design through deployment and infrastructure

  • Leverage AI-assisted development tools to accelerate delivery, improve code quality, and stay at the cutting edge of modern engineering practices

What you'll need for this role

  • Solid experience of professional React Native or React development experience with a proven track record of delivering production web applications
  • Deep, hands-on experience building and shipping real products
  • Strong expertise in JavaScript/TypeScript, modern React patterns (hooks, server components, suspense), state management, and web platform fundamentals
  • Experience with setting up and managing deployments of web applications – you've done this, not just read about it
  • Strong understanding of HTTP caching – you know when to cache, where to cache, and how to invalidate without breaking things
  • Battle-tested experience measuring and optimising web application performance – you've profiled, diagnosed, and fixed real performance bottlenecks in production
  • Experience building and optimising CI/CD pipelines for web deployments – you care about build speed, deployment stability, and developer experience
  • Experience with real-time data handling, WebSocket connections, and high-frequency data updates
  • Experience with AI-assisted development tools – we're looking for engineers who see AI as a force multiplier, not a threat

How we work

We try to take a thoughtful approach to our ways of working as a company. We follow a hybrid working model with 3 days in the office -- which we think balances the need to collaborate effectively and connect with each other. When it comes to how we deliver, there are 5 things we want everyone to do to drive high performance, better learning and career satisfaction:
