Senior Java Fullstack Developer – FX Trading Platforms


📍 Location: Krakow, Poland (Hybrid – 2 days/week in office)
📝 Contract: B2B, Long-Term Collaboration


Join a global engineering team building mission-critical financial systems at the heart of the FX (Foreign Exchange) market.

We’re looking for an experienced Java Fullstack Developer ready to step into a high-impact role where performance, clean architecture, and fast delivery matter.


You’ll work in a cross-functional, agile pod, releasing production-ready code daily, owning services end-to-end — from development to monitoring.




What You'll Be Working On




  • Designing, developing, and maintaining low-latency, high-throughput systems handling large-scale FX transactions (hedging, prime brokerage, execution management).




  • Contributing to microservices-based architecture (~100–150 running services) with high autonomy over feature design and delivery.




  • Building modern UIs with React and/or Angular, closely aligned with backend components written in Java + Spring Boot.




  • Collaborating across time zones with global teams (London, Toronto, Guangzhou) in a DevOps-driven environment.




  • Ensuring code quality through automated testing, CI/CD pipelines, instrumentation, and observability best practices.






Tech Stack & Tools




  • Backend: Java 11+, Spring Boot, RESTful APIs




  • Frontend: React, Angular, TypeScript, JavaScript




  • Database: PostgreSQL, Oracle, Sybase




  • DevOps: Git, Jenkins, Docker, Kubernetes (basic exposure), CI/CD automation




  • Testing & Monitoring: JUnit, Mockito, Grafana, ELK stack, SonarQube




  • Agile: Jira, Confluence, Scrum/Kanban practices






Who We're Looking For




  • 3–7 years of experience as a Fullstack or Backend Java Developer.




  • Hands-on experience with microservices, REST APIs, Spring Boot.




  • Solid understanding of relational databases and data consistency in distributed systems.




  • Experience with modern frontend frameworks (React or Angular) is a big plus.




  • Passion for DevOps culture — you build it, you own it.




  • Comfortable working in Agile teams and collaborating with international stakeholders.




  • Fluent English – spoken and written.
