Software Engineer (Java) Full Time NEW

Software Engineer (Java)

Job Description

So, who are we?

IG Group is a FTSE 100 fintech operating across five continents, serving over 1.3m customers and handling billions of dollars in transactions – built on 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.

Your team

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 role in the Team’s Success

You’ll be the engineering force behind services that handle massive transaction volumes, real-time market data, and split-second decision making. Your primary responsibility is designing and building backend systems that are robust, observable, and wickedly fast. You won’t just write code – you’ll own the full lifecycle from architecture to production, ensuring our systems perform flawlessly when millions of pounds are on the line. 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.

We believe in “you build it, you run it, you love it” – so if that ownership mindset excites you, keep reading.

What You’ll Do

• Design, build, and maintain high-performance Java services (Spring Boot WebFlux/MVC) that handle real-time trading operations and massive data throughput
• Own the full stack from code to cloud – architect solutions, build CI/CD pipelines, deploy to Kubernetes (AWS EKS), and keep production humming
• Partner with Product, Design, and Frontend teams to deliver features that move the needle for our clients and business – not just tick boxes
• Actively participate in product development, from requirements discussions to seeing customers using your software in production
• Contribute to implementing observability that matters – build monitoring, alerting, and tracing (Grafana, Honeycomb, OpenTelemetry) that catches issues before clients notice them
• Champion technical excellence in performance, scalability, and security – in fintech, “good enough” isn’t good enough
• Troubleshoot and resolve production incidents with urgency and precision – when something breaks at 3am, you’re the person who fixes it (and then makes sure it never breaks again)
• Contribute to technical discussions, participate in thoughtful code reviews and knowledge sharing
• Leverage AI-assisted development tools to accelerate delivery, improve code quality, and stay at the cutting edge of modern engineering practices
• Challenge the status quo – question architectural decisions, propose improvements, and help shape our technical direction

What You’ll Need For This Role

• For this role, we’re looking for solid backend engineering experience with Java as your weapon of choice (Spring Boot, REST/gRPC, reactive patterns)
• Battle-tested experience running production workloads on Kubernetes (AWS EKS preferred) – you’ve debugged pod crashes at midnight and lived to tell the tale
• Knowledge of relational databases (PostgreSQL) and caching layers (Redis)
• Understanding of DevOps chops: CI/CD pipelines (GitLab CI), infrastructure-as-code (Terraform), and container orchestration aren’t buzzwords to you they’re daily tools
• Experience with distributed systems, microservice architectures, and the observability tooling needed to keep them healthy
• A security-first mindset baked into how you design and code – not bolted on as an afterthought

Key Qualification Requirements

• An ownership mindset that borders on obsessive – you treat every system like you built it with your own money
• 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
• Drive to continually succeed; always working towards engineering excellence – you advocate for practices like pair programming, test-driven development (TDD), and automated testing not because a process demands it, but because you’ve seen how they elevate code quality and team capability
• Strong English-language communication skills and the ability to thrive in globally distributed, cross-functional teams
• Hunger for continuous learning – you’ll gain deep understanding of IG’s trading products, financial markets, and the complex regulations that govern them
• Familiarity with financial services, trading platforms, or crypto/fintech is a plus – but we’ll teach you if you bring the engineering firepower
• Willingness to participate in on-call rotations – production ownership means being there when it counts This is a hybrid position (3 days onsite, 2 days remote work)

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:

• 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.
