Video Streaming Engineer (Wowza, AWS Elemental)

CACI International • Ashburn, VA

7d • $103,800 - $218,100 • Hybrid

About The Position

CACI is seeking a Senior Video Streaming Engineer with Agile methodology experience to join their BEAGLE (Border Enforcement Applications for Government Leading-Edge Information Technology) Agile Solution Factory (ASF) Team supporting the Customs and Border Protection (CBP) client. In this role, the engineer will be the program's video delivery expert, responsible for designing, building, and optimizing end-to-end Full-Motion Video (FMV) streaming pipelines using Wowza Streaming Engine and AWS Elemental media services. The engineer will collaborate with Enterprise Architects and Technical Leads to design and implement low-latency live video streaming topologies using protocols like HLS and WebRTC, and explore future-state technologies like SRT (Secure Reliable Transport) for tactical edge operators.

Requirements

• Must be a U.S. Citizen with the ability to pass a CBP background investigation.
• College degree (B.S.) in Computer Science, Information Technology, Electrical/Computer Engineering, or a related technical field (equivalent experience accepted in lieu of degree).
• 7+ years of experience in systems engineering, software engineering, or network engineering.
• Minimum of 3+ years of dedicated, hands-on experience engineering live enterprise video streaming systems.
• Advanced administration, tuning, and clustering of Wowza Streaming Engine (or similar enterprise media servers).
• Configuring cloud-native workflows using AWS Elemental MediaLive, MediaConnect, MediaPackage, and CloudFront CDN.
• Working knowledge of HLS, WebRTC, RTMP, and transport stream protocols.
• Strong understanding of SRT (Secure Reliable Transport) mechanics (e.g., packet recovery, ARQ, latency tuning over public networks).
• Operating and configuring Linux-based environments (RHEL, Ubuntu) where streaming software is hosted.
• Understanding routing protocols, multicast vs. unicast, firewalls, ports, NAT traversal, QoS, and bandwidth constraints.
• Analyzing video streams using diagnostic tools, packet analyzers (Wireshark), and command-line media tools like FFmpeg and ffprobe.

Nice To Haves

• Agile methodology experience

Responsibilities

• Collaborate with System Architects and Tech Leads to design, deploy, and maintain highly resilient, enterprise-scale video streaming architectures across hybrid (cloud and on-premises) environments.
• Install, configure, cluster, and optimize Wowza Streaming Engine servers to handle high-concurrency ingestion and distribution.
• Configure, monitor, and optimize cloud media workflows using the AWS Elemental Suite (including Elemental MediaLive, MediaConvert, MediaPackage, and MediaStore).
• Implement and tune streaming video protocols including HLS, WebRTC, RTMP, and RTP/UDP, with a strong focus on deploying SRT (Secure Reliable Transport) for secure, low-latency streaming over unpredictable networks.
• Configure and optimize video codecs (H.264/MPEG-4 AVC, H.265/HEVC), transcode profiles, frame rates, adaptive bitrate (ABR) streaming, and keyframe intervals for optimal performance over low-bandwidth environments.
• Deep-dive into complex video streaming issues such as frame drops, audio-video synchronization issues, latency bottlenecks, caching issues, and decoder incompatibilities.
• Partner with security engineers to implement content encryption, DRM, secure token authentication, and TLS-wrapped streaming protocols to safeguard sensitive video assets.
• Write scripts (Python, Bash) to automate video ingestion pipelines, server provisioning, and performance monitoring.
• Establish real-time QoS/QoE monitoring and alerting for all active video streams.
• Actively participate in sprint planning, retrospectives, daily stand-ups, and product demonstrations, delivering production-ready configurations and features in short sprint cycles.
