As we expand our R&D on Dante Embedded Platform (DEP), we’re looking for a freelance Network Engineer with strong Linux and AoIP expertise to help us scale and optimize our embedded networking stack.

KEY RESPONSIBILITIES:

- Design and maintain Dante Embedded Platform (DEP)-based AoIP networks for real-time immersive audio.

- Configure and manage VLANs, DHCP pools, ACLs, and routing across multi-segment media networks.

- Optimize Ubuntu-based systems for low-latency Dante performance, including kernel and stack tuning.

- Contribute to the C++ rework of our internal Dante DEP driver layer, with attention to performance and modularity.

- Troubleshoot complex system/network behaviors across audio, video, and control layers.

- Collaborate with R&D and application engineers to ensure full integration and field readiness.

- Write and maintain clear, precise documentation of all configurations and processes.

QUALIFICATIONS/EXPERIENCE:

- Proven experience in Linux network administration, ideally on Ubuntu.

- In-depth knowledge and hands-on work with Audinate Dante, particularly Dante Embedded Platform.

- Solid experience in C++, especially at system or driver level.

- Capacity to work autonomously in complex, multi-layered environments.

- Fluency in English (written and spoken); French is a plus.

DESIRED SKILLS:

- Master’s Degree in Computer and Network Engineering or a related field.

- Experience with real-time audio systems and network optimization for low jitter/latency.

- Understanding of Precision Time Protocol (PTPv2) and clocking challenges in AoIP.

- Familiarity with embedded development environments, network stacks, or driver APIs.

- Strong communication and documentation skills.

- Appetite for cutting-edge innovation in sound and acoustics.
