Roku is looking to build, optimize, and maintain high-performance video processing workflows for their Cloud TV Platform to deliver a best-in-class streaming TV experience globally.
Requirements
- Expert-level knowledge of FFmpeg or Gstreamer and their related toolchains (filters, flags, debugging, custom builds)
- Experience with hardware-based encoder/decoder libraries (NVENC, Vulkan)
- Strong understanding of compression theory, codec internals, GOP structures, bitrate control, etc
- Experience with container formats: MP4, TS, fragmented MP4, ISOBMFF
- Familiarity with HLS/DASH, CMAF, adaptive bitrate design, DRM, and SCTE 35
- A track record working with applied AI-based video enhancement and compression algorithms (Super Resolution, Denoising, Artifact Removal)
- Hands-on experience with cloud compute (AWS Lambda/ECS/Batch, GCP, Kubernetes, or similar)
Responsibilities
- Design, build, optimize, and maintain FFmpeg-based encoding pipelines for both VOD and Live workflows, operating at scale in cloud environments such as AWS or GCP
- Develop, refine, and validate encoding presets for modern codecs, including H.264, HEVC, and AV1, ensuring optimal quality-to-bitrate performance
- Implement advanced encoding strategies such as multi-pass workflows, CRF tuning, per-title optimizations, and quality-targeted encoding
- Benchmark and evaluate video quality using VMAF and other objective metrics to drive continuous improvements in efficiency and viewing experience
- Build and maintain adaptive streaming packaging workflows, including HLS, DASH, and CMAF, ensuring broad device compatibility and reliable playback
- Profile and optimize system performance by identifying and eliminating bottlenecks across compute, storage, and I/O layers
- Write, review, and improve code, assessing architectural tradeoffs to deliver secure, high-performance, and highly concurrent video infrastructure services
Other
- Strong problem-solving and analytical abilities
- 5+ years of solid programming experience and passionate about writing high-quality and well-architected code
- Ability to handle periodic on-call duty as well as out-of-band requests; strong written and verbal communication skills
- The estimated annual salary for this position is between $285,000 - $345,000 annually.
- Our Hybrid Work Approach: Roku fosters an inclusive and collaborative environment where teams work in the office Monday through Thursday.
