What will you do:

Design, implement, and maintain high-performance backend components supporting bond and derivative trading systems. 

Develop and optimize low-latency services, ensuring reliability and scalability. 

Collaborate with other senior engineers to build internal frameworks and custom libraries. 

Investigate and fine-tune existing codebases, especially at the library/tooling level. 

Work with messaging infrastructure to support complex trading workflows, including in-memory topic management. 

Cooperate with quants, traders, and product teams to translate business needs into robust technical solutions. 

Maintain system integrity by ensuring thread safety, messaging consistency, and fault tolerance. 

Contribute to the evolution of backend architecture and continuously look for performance improvements 

 

Your skills:

10+ years of professional software engineering experience, with a strong focus on backend systems. 

Expert-level knowledge of Java  

Deep experience with Spring and custom in-house frameworks (e.g., Falcon or similar). 

Proven ability to work on low-latency systems and build custom tooling. 

Comfortable with low-level programming (e.g., diving into libraries, modifying or extending functionality as needed). 

Solid understanding of multithreading and concurrency in Java. 

Proficiency with WebSockets and multicast communication patterns. 

Experience working with MongoDB or other NoSQL databases. 

Familiarity with functional programming paradigms. 

Hands-on experience with messaging systems, including:  

At least three messaging tools (e.g., Solace, in-memory topics). 

Designing and working with high-performance messaging infrastructure. 

 

Nice to have: 

Experience with Scala, or willingness to learn on the job. 

Knowledge of native database access libraries (e.g., bypassing ORMs for performance-critical access). 

Understanding of fixed income trading, specifically:  

Bond trading and derivative instruments. 

Order placement, pricing algorithms, position management, and risk assessment. 

Exposure to post-trade processing, settlements, and reconciliation (e.g., Spectre system). 

Experience building data pipelines focused on data integrity and consistency (rather than large-scale data processing).
