What will you do? 

 

You will be fully involved in the development of a high-performance FX trading platform, working closely with the Client’s engineering team. The system includes components such as real-time pricing engines, connectivity to exchanges and market data providers (e.g. Bloomberg), and infrastructure supporting low-latency execution. Your core responsibility will be the design, development and continuous optimization of trading components with a strong focus on throughput and latency. The role requires a deep understanding of high-frequency trading architectures, efficient memory management, and performance-critical Java development. You’ll be working in an environment where microseconds matter — contributing directly to the speed, stability, and scalability of the system. 

 

Your tasks:

 Design, develop, and maintain components of a high-performance FX trading platform  Optimize system architecture and application code for ultra-low latency and high throughput  Implement and enhance real-time pricing engines and market data connectivity (e.g. Bloomberg, exchanges)  Collaborate closely with the Client’s engineering team in a hybrid model (2 days/week onsite)  Apply advanced Java techniques (off-heap memory, lock-free algorithms, GC tuning) in performance-critical contexts  Ensure reliability and scalability of the trading infrastructure under high load  Participate in code reviews and contribute to high-quality engineering standards  Monitor and profile application performance using appropriate tools and methodologies  Work in an agile environment with active involvement in technical discussions and continuous improvement 

  

Your skills :

  

At least 5 years of practical experience in Java with focus on low latency performance optimization (off-heap memory management, lock-free algorithms, GC tuning)  Deep understanding of high-frequency trading system architecture  Experience with specialized trading protocols (FIX, FAST, market-specific binary protocols)  Practical experience in implementing design processes ensuring high quality of solutions provided  Practical knowledge of the Scrum methodology or similar agile methodology  Good communication skills and ability to establish effective cooperation with clients  Fluent English and readiness for frequent written, phone or direct communication  Availability to work in a hybrid mode – twice a week from the office (GFT or client) 

  

Nice to have :

   

Experience with time-series databases and real-time analytics platforms  Experience with capacity planning for trading system infrastructure  Knowledge of Test Driven Development methodology  Experience with FPGA, hardware acceleration or co-located exchange connectivity  Familiarity with performance profiling tools (JMH, YourKit, Honest Profiler)  Work experience in distributed teams 

  

We offer you:

  

Hybrid work – 2 days a week in our/our client's office  Working in a highly experienced and dedicated team  Competitive salary and extra benefit package that can be tailored to your personal needs (private medical coverage, sport & recreation package, lunch subsidy, life insurance, etc.)  Contract of employment or B2B contract    On-line training and certifications fit for career path  Free on-line foreign languages lessons  Regular social events   Access to e-learning platform  Remote work option available for candidates outside GFT office locations (Lodz, Krakow, Warszawa, Poznan, Wroclaw).
