Overview

Hello, we're IG Group. We are an FTSE250 FinTech company who run mobile, web and desktop platforms that help our clients trade stocks & shares, leveraged products, Futures & Options and Crypto. We are ambitious. Over 340,000 people already use our platforms. We're global with offices in 18 countries and products in 16 regions. We're hungry to move faster, ship better product for our customers and grow our user base. We believe in high autonomy, and we want people who are looking to do things differently in order to create better experiences for our customers. We work in cross-functional teams and are laser-focused on increasing the number of active clients we serve to drive sustainable growth. 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:

• Lead and Inspire: Drives trust, alignment, and enthusiasm

• Collaborate closely with Product, Design, and Frontend teams to deliver business-critical features.
• Drive technical excellence in performance, scalability, and security, especially in a crypto/fintech context.
• Troubleshoot and resolve production incidents with a proactive, ownership mindset.
• Strong backend engineering skills in Java (Spring Boot, REST/gRPC, Postgres, Redis).
• Proven experience running production workloads on Kubernetes (AWS EKS preferred).
• Solid knowledge of DevOps practices, including CI/CD pipelines, infrastructure-as-code (Terraform), and container orchestration.
• Experience with observability tooling and performance troubleshooting in distributed systems.
• Security-first mindset, with understanding of secure coding and deployment practices.
• Proactive problem-solver with the ability to work independently and collaboratively in a high-performance team.
