Amazon CloudFront is seeking a Sr. Software Dev Engineer for its Video Delivery team in Seattle, focusing on global-scale video systems. The role will involve innovating with LL-HLS, Sye, and Media over QUIC (MOQ) for live and on-demand streaming, and driving technical strategy for video delivery infrastructure. This position emphasizes building reliable, scalable, low-cost systems and addressing challenges in real-time content packaging and adaptive bitrate streaming.
AWS’s commitment to MOQ signals a shift away from the ‘latency-scale trilemma’ that has forced trade-offs between WebRTC’s speed and HLS’s reach. By moving MOQ into its core Video Delivery stack, Amazon is positioning CloudFront to capture high-value interactive traffic such as sports betting and live commerce, which require sub-500ms delivery. This move pressures competitors like Akamai and Cloudflare, the latter of which launched a production MOQ relay network in August 2025. For the broader ecosystem, it validates QUIC-based transport as the successor to segment-based HTTP streaming. Watch for future AWS Elemental integrations that automate the transition from LL-HLS to MOQ-native delivery as browser support for WebTransport reaches critical mass.
Amazon CloudFront's push into Media over QUIC places it in direct competition with Cloudflare, which launched the first production MoQ relay network across every server in more than 330 cities in August 2025, offering the service free of charge during a tech preview period. Cloudflare has since expanded that deployment with a MoQ relay provisioning API that lets developers create isolated relays with separate publisher and subscriber credentials, supporting draft-14 and draft-16 versions of the MoQ Transport protocol. More than 1,000 unique clients connect daily to test against Cloudflare's open MoQ endpoints, giving the company a head start in developer adoption that Amazon's Video Delivery team will need to match.
At IBC 2026, the MOQ ecosystem reached an inflection point when Oracle OCI, Amazon AWS, and Akamai all declared they were going all-in on MOQ, though none expects commercial readiness until the April 2027 NAB timeframe. Beta testing over partner CacheFly's global CDN and other MOQ-equipped CDNs operated by Cloudflare, CDN77, Vindral, Broadpeak, and Netskrt provided proof of concept at global scale. The same reporting noted that at least one major newcomer's IBC demo failed to achieve latency below one second or the planned real-time interactivity, underscoring the engineering difficulty Amazon's new hire will face.
Amazon CloudFront's existing video delivery architecture already handles large-scale live events. At AWS re:Invent 2025, AWS specialists Jamie Mullan and John Councilman detailed CloudFront's 750-plus edge locations and its integration with AWS Elemental MediaConnect, MediaLive, and MediaPackage for end-to-end live workflows, including NESN's direct-to-consumer streaming of Red Sox and Bruins broadcasts. The addition of MOQ and Sye to that stack represents Amazon's effort to extend the same infrastructure from traditional segment-based delivery into sub-second interactive use cases without requiring customers to migrate to a separate platform.
