- Contribute to code reviews, architectural discussions, and technical audits to maintain high standards throughout the codebase.
- Utilize AI-driven coding tools to accelerate development and enhance productivity where applicable.
Requirements
- Over 5 years of Java backend development experience, preferably in trading or real-time system contexts.
- Proficiency in Java core internals, multithreading, memory models, and garbage collection concepts.
- Demonstrable expertise in GC-free or low-GC programming, incorporating techniques such as sun.misc.Unsafe, direct buffers, and memory-mapped files.
- Familiarity with low-latency messaging libraries like Aeron and SBE.
- Strong grasp of event-driven architecture and experience in designing fully deterministic systems.
- Sound knowledge of time-series and analytical databases such as ClickHouse, with exposure to kdb+ or InfluxDB desirable.
- Experience with distributed systems, message queues, and performance optimization at both network and application layers.
- Comfortable with using AI-powered development tools to promote code quality and speed up development.
- Proficient in testing practices including TDD, benchmarking, and resilience testing.
