• Experience with hardware-based encoder/decoder libraries (NVENC, Vulkan)
• Strong understanding of compression theory, codec internals, GOP structures
• Familiarity with container formats (MP4, TS, fMP4, ISOBMFF) and streaming protocols (HLS, DASH, CMAF)

Responsibilities

• Design, build, optimize, and maintain FFmpeg-based encoding pipelines for VOD and Live workflows in cloud environments
• Develop and validate encoding presets for H.264, HEVC, and AV1
• Implement advanced encoding strategies like multi-pass, CRF tuning, per-title optimizations
• Build and maintain adaptive streaming packaging workflows (HLS, DASH, CMAF)
• Profile and optimize system performance across compute, storage, and I/O layers
