Software Engineer (Java)

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 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, trad
