Job Title

Job Description

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 are IG UK’s Crypto Product Engineering team, building the company’s #1 strategic priority for the UK market. Our mission is to deliver a secure, scalable, and high-performing crypto trading platform, ready for launch in 2025. 

As a Senior Backend Engineer (IC), you will be at the core of building and running IG’s new crypto offering. You’ll design and implement high-performance, cloud-native backend services, while owning key DevOps responsibilities to ensure our systems are robust, observable, and secure. You will be trusted to move fast, solve complex problems, and take full ownership from code to production. 

• Design, build, and maintain cloud-native backend services in Java (Spring Boot WebFlux/MVC). 

• Own and improve CI/CD pipelines (GitLab CI, Docker, Kubernetes on AWS EKS). 

• Implement and maintain observability, monitoring, and alerting (Grafana, Splunk, OTEL). 

• 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. 

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

• Think Big: Focus on the problems that most impact commercial outcomes

• Champion the client: Understand and prioritise client's needs

• Deliver at pace: Push for fast, sustainable growth;

• Raise the bar: Take ownership, be accountable and share feedback

We believe that diversity is vital to success, it fuels creativity, drives innovation and sets us up for global success. We're committed to building teams with a variety of perspectives and skills to help us realise our vision and strategy, that's why we encourage applications from people with diverse backgrounds and experiences to join us on this journey.
