Role Description We’re seeking a Senior Java Video Streaming Engineer with deep expertise in backend Java with direct experience writing code for a streaming server or engine (e.g., Wowza, FFmpeg, Ant Media, Red5) to join our engineering team. In this role, you will architect, implement, and optimize live and on-demand streaming pipelines in Wowza Streaming Engine. We are looking for someone with deep expertise in streaming video standards and a low level understanding of the key components in video processing. - Design and develop core features within Wowza Streaming Engine designed for testability and scale. - Design and implement advanced transcoder workflows for new codecs and accelerators. - Design and implement highly scalable packaging workflows. - Debug and resolve customer reported issues, bugs and performance issues. - Participate in cross-functional projects from conception through deployment. - Be a resource to other team members as a streaming subject matter expert. Qualifications - 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. - 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). Requirements - Experience with C/C++ development and ability to read, debug, and contribute to native codebases that interface with Java via JNI. - Contributions to open-source video projects such FFmpeg or gStreamer. - Experience with Wowza Streaming Engine. - Understanding of build (CI/CD) and test automation frameworks for large scale software. - Experience creating and documenting public APIs and creating publicly available SDKs. Benefits - Salary Range: $175,000 - 200,000 - Generous Paid Time Off - Medical, Dental, and Vision insurance (effective Day 1) - 401(k) with strong company match - Dependent Care FSA - Employer-paid Life Insurance and AD&D - Voluntary Life Insurance (Employee/Spouse/Child) - Paid Parental Leave - Short-Term and Long-Term Disability - Training & Development opportunities - Employee Assistance Program (EAP)
