Job description

Description

We’re seeking a Senior Java Video Streaming Engineer with deep expertise in transcoding,

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.

What You’ll Do

• 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.

Requirements

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).

Nice to Have

• 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

  • 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)
