Software Engineer (Java)

Team

You are a part of IG UK’s Crypto product engineering team, responsible for a fully licensed, FCA‑regulated crypto trading platform launched in December 2025.

Responsibilities

• 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 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.

Qualifications

• Solid backend engineering experience with Java (Spring Boot, REST/gRPC, reactive patterns).
• Battle‑tested experience running production workloads on Kubernetes (AWS EKS preferred) – 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.
• 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.
