Technical Requirements

Java Expertise (Core Requirement)

8+ years of hands-on Java development in performance-critical, large-scale systems.
Deep understanding of Java concurrency and multithreading — thread pools, locks, synchronization, concurrent data structures, and designing thread-safe components for high-throughput workloads.
Strong knowledge of JVM internals including garbage collection tuning (G1, ZGC, Shenandoah), heap/off-heap memory management, and GC pause optimization for latency-sensitive applications.
Proven ability to optimize Java applications for memory, CPU, and GPU utilization using standard Java profiling and diagnostic tools.
Experience with JNI (Java Native Interface) for integrating Java with native C/C++ libraries and managing cross-boundary memory and threading safely.
Experience with Unit testing, performance testing/tuning (heap dump analysis, thread dump analysis), and debugging complex multithreaded Java applications.

Video Streaming & Domain Knowledge

5+ years’ experience in transcoding and packaging workflows (Wowza or similar).
Deep knowledge of video codecs: H.264/AVC, H.265/HEVC, VP8/VP9, AV1.
Hands-on experience with GPU or VPU accelerated transcoding pipelines.
Extensive experience with one or more of the common streaming protocols – RTMP, RTSP, HLS, MPEG-DASH, CMAF, WebRTC.
Knowledge of content encryption and DRM.
Familiarity with video quality metrics (PSNR, SSIM, VMAF).
