Job Title
Frontend Engineer (React Native)
Job Description
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.
We are IG UK's Crypto product engineering team, having successfully delivered the company's #1 strategic priority - a fully licensed, FCA -regulated crypto trading platform launched in December 2025. We maintain elite engineering standards through cloud-native AWS architecture, comprehensive observability, and a culture of end-to-end ownership where engineers drive product outcomes, not just technical deliverables.
Your primary responsibility will be to lead the development of complex React Native features for our award-winning trading platforms across mobile and web.
You'll architect scalable solutions that handle real-time financial data streams and high-frequency trading operations on any device.
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 enables traders to seize market opportunities.
Extensive experience of React Native development with a proven track record of delivering production mobile and/or web applications
Strong expertise in JavaScript/TypeScript, React hooks, Redux/Context API, and cross-platform development best practices
Experience with native mobile development (iOS/Android) and ability to write custom native modules when needed
Solid understanding of React performance optimization, including memory management, rendering optimization, and efficient API integration
Experience with real-time data handling, WebSocket connections, and high-frequency data updates
Knowledge of CI/CD pipelines, automated testing frameworks, and deployment processes
Experience with AI-assisted development tools - we're looking for engineers who see AI as a force multiplier, not a threat
AI-positive mindset - you see AI tools as amplifiers of engineering capability, not replacements, and you're excited to push the boundaries of what's possible with AI-assisted development
Strong English-language communication skills and the ability to work effectively in globally distributed, cross-functional teams
A keen interest in ongoing learning, both business and technical – you'll gain deep understanding of IG 's trading products and financial markets
Familiarity with financial services or trading platforms is highly desirable but not essential
Excellent problem-solving skills with a quality-first, ownership mindset – you build it, you run it, you love it
