United Kingdom WSN Full time

WSN is seeking a seasoned Java expert with a strong background in threading, memory management, and performance tuning. The ideal candidate understands the subtleties of Java’s memory model, including pointer-like references, and can effectively profile and optimize Java applications to ensure top-tier performance. This role demands deep technical expertise in threading, concurrency, and JVM internals to address performance challenges in critical systems.


Key Responsibilities:

  • Threading Optimization: Diagnose and resolve threading issues, including deadlocks, race conditions, and contention, to enhance application responsiveness and stability.
  • Memory Management: Optimize memory allocation strategies, reduce garbage collection overhead, and fine-tune applications for efficient memory usage.
  • JVM Tuning: Profile JVM behavior (e.g., garbage collection, JIT compilation, and memory usage) and adjust settings to maximize performance.
  • Performance Profiling: Use tools like JProfiler, YourKit, and VisualVM to identify bottlenecks and inefficiencies in multi-threaded Java applications.
  • System-Level Optimization: Optimize the interaction between Java applications and the Linux OS, focusing on I/O, scheduling, and resource management.
  • Best Practice Implementation: Collaborate with development teams to implement threading-safe patterns, optimize locking mechanisms, and improve code efficiency.
  • Technical Documentation: Produce clear, detailed reports of performance issues, solutions, and recommended best practices.
  • Team Mentorship: Share knowledge and guide teams on threading, memory management, and performance tuning best practices.


Qualifications:

  • Extensive experience in threading and concurrency in Java, including synchronization, lock-free programming, and thread pool management.
  • Strong understanding of Java’s memory model, including reference handling, memory leaks, and garbage collection tuning.
  • Deep expertise in JVM internals, including heap and stack management, JIT optimization, and GC algorithms.
  • Proficient in Java profiling tools (e.g., JProfiler, YourKit) and performance monitoring frameworks.
  • Hands-on experience optimizing Java applications in a Linux environment, with an understanding of OS-level factors that impact performance.
  • Excellent problem-solving skills with a data-driven approach to diagnosing and resolving performance bottlenecks.
  • Strong communication skills, with the ability to explain complex concepts to technical and non-technical stakeholders.
  • Prior experience in cross-regional collaboration is a plus.
