About the Project – QUICast
QUICast is a research and development project that explores a new paradigm for scalable live video delivery by combining IP multicast with modern transport protocols such as QUIC. The goal is to significantly improve the efficiency and scalability of large-scale live streaming compared to traditional unicast-based approaches.

The project is funded within the xG-Incubator program and runs for an initial 12-month development phase, during which a functional demonstrator will be implemented and evaluated in a real-world environment.

QUICast brings together expertise in network protocols, distributed systems, video streaming, and client applications. If the project is successful, a startup spin-off is planned in a second phase to further develop and deploy the technology.

We are building a small, highly technical team to design and implement the core components of this system.

The work builds on the IETF Internet-Draft “QUIC Multicast”, co-authored within the project, and aims to develop a prototype implementation and experimental evaluation.

The position is initially limited until 31/05/2027; if the project successfully leads to a startup spin-off, there will be if necessary an opportunity to continue working on the technology within the new company.

To strengthen our team, we are looking for a Video Streaming Engineer who will focus on enabling efficient live video transmission from the multicast source to client devices.

Your responsibilities will include:

• Designing and implementing the video streaming pipeline for QUICast
• Integrating existing video codecs and streaming mechanisms for initial unicast-based delivery
• Developing and evaluating adaptive video delivery mechanisms optimized for multicast environments
• Implementing packet loss resilience mechanisms, including Forward Error Correction (FEC)
• Designing and testing layered or scalable video encoding approaches
• Optimizing Quality of Experience (QoE) under varying network conditions
• Evaluating server efficiency and bandwidth utilization for multicast-based delivery
• Working closely with the backend and client developers to integrate the video pipeline into the full system
• Conducting performance evaluations and experimental measurements

Expected Outcomes After One Year
At the end of the first project phase, the video streaming system should achieve the following milestones:

• Fully functional live video playback on the client side
• Rebuffering rate below 5% during typical playback conditions
• Stable Quality of Experience (QoE) under packet loss rates up to 3%, enabled for example through Forward Error Correction (FEC)
• A prototype layered or scalable video codec or streaming architecture deployed within the system that improves either:

1. Average user QoE, or
2. Server-side efficiency and bandwidth utilization

• Successfully completed univrsity degree (Master, Diplom or equivalent) in Computer Science, Computer Engineering, Media Technology, or a related field
• Good understanding of video streaming technologies and codecs
• Familiarity with real-time video delivery systems
• Basic knowledge of networking concepts, particularly:

1. Transport protocols
2. QUIC
3. IP multicast

• Experience with video processing frameworks or streaming pipelines
• Ability to work independently in a small, focused development team desirable
• Interest in developing novel media delivery systems desirable
• Good knowledge of German and/or English required; willingness to acquire the respective missing language skills
• Experience with video codecs such as H.264, H.265, AV1, or VP9 desirable
• Experience with adaptive streaming technologies (e.g., DASH, HLS) desirable
• Experience with scalable or layered video coding desirable
• Familiarity with FFmpeg, GStreamer, or similar media frameworks desirable
• Knowledge of error resilience mechanisms such as FEC desirable
• Experience evaluating video Quality of Experience (QoE) desirable

• Opportunity to work on next-generation video delivery technology
• A chance to shape a potential startup technology from the ground up
• Work in a small, highly technical and focused team
• The possibility to contribute to real-world deployment of novel streaming architectures
