Full Job Description
đź“‹ Description
- • Join a brand-new strategic initiative inside ION Group that is re-imagining how the world’s largest banks, central banks and governments trade, analyse risk and manage workflows. You will be one of the first engineers on the ground, shaping architecture, culture and product direction from day one.
- • Own the end-to-end delivery of high-throughput, low-latency Java services that process millions of market events per second. Your code will sit at the heart of trading floors in 40+ countries and directly influence trillions of euros in daily transaction volume.
- • Design and evolve domain-driven micro-service ecosystems using Java 8/11, Spring Boot, Guice, Hibernate and reactive patterns. You will champion clean hexagonal architectures, dependency injection and event sourcing to keep complexity under control as the platform scales.
- • Pair with cross-functional squads that include quant researchers, UX designers, product managers and network engineers. Together you will translate regulatory change, trader feedback and cloud opportunities into shippable increments every two weeks.
- • Drive non-functional excellence: sub-millisecond latency budgets, horizontal scalability on AWS, zero-downtime blue/green deployments via Docker & Kubernetes, and bullet-proof disaster recovery across multiple regions.
- • Practise strict TDD/BDD—every line of production code is preceded by failing tests in JUnit 5, Cucumber or Spock. You will maintain >90 % coverage and guard it with automated quality gates in Jenkins, SonarQube and Fortify.
- • Contribute to the company-wide Continuous Delivery platform: extend Maven archetypes, write Gradle plugins, template Terraform stacks and coach teams in Rome, London and New York on safe, frequent releases.
- • Become a mentor and technical anchor. Run brown-bag sessions on functional programming with Java 8 streams, conduct code reviews that raise the bar, and sponsor graduate hires through their first production incident.
- • Experiment fearlessly: prototype event-driven designs with Kafka, evaluate Project Loom for virtual threads, and benchmark GraalVM native images. If it moves the needle for performance or developer joy, you have budget and air cover to try it.
- • Influence product strategy. Your dashboards and post-trade analytics will surface insights that help central banks calibrate monetary policy and help corporate treasurers hedge FX risk in real time.
- • Work in one of our premium tech hubs—Pisa, Milan, Turin, Collecchio or Rome—or blend remote and on-site in a way that maximises focus and collaboration. Fast fibre, standing desks, 34-inch curved monitors and quiet zones come as standard.
- • Thrive in a culture that measures impact, not hours. We deploy to production 200+ times a week, celebrate learning from failure, and give every engineer 10 % time to contribute to open-source or pursue patents.
🎯 Requirements
- • University degree (BSc or higher) in Computer Science, Computer Engineering or related STEM field
- • 5+ years of professional Java development with deep expertise in Java 8/11, Spring, Hibernate and concurrent programming
- • Proven mastery of TDD/BDD, automated testing and continuous integration/delivery pipelines (Git, Maven, Jenkins, Docker)
- • Experience designing high-performance, low-latency distributed systems in AWS or similar cloud environments
- • Nice to have: functional programming exposure (streams, lambdas, Vavr), event sourcing, CQRS, Kafka, Kubernetes, financial markets domain knowledge
🏖️ Benefits
- • Competitive, performance-linked salary reviewed annually plus annual bonus
- • Permanent full-time contract with flexible hybrid/remote work arrangements
- • Comprehensive on-the-job and structured training programmes (tech talks, certifications, conference budget)
- • Premium private health insurance, pension plan, meal vouchers and wellness allowance
- • Relocation support and visa sponsorship for non-EU candidates who already hold a valid work permit
