Software Engineer; Java

Requirements

• 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 (Postgre
  
  SQL) and caching layers (Redis)
,
• Understanding of Dev Ops chops: CI/CD pipelines (Git Lab 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
,
• 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

• 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
,
• Design, build, and maintain high-performance Java services (Spring Boot Web Flux/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, Open Telemetry) 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
