We are seeking a hands-on Principal Engineer/Architect to lead the development of next-generation software Digital/Network Video Recorder (DVR/NVR) systems on embedded Linux platforms. 

Our client is a leading mobility technology provider that develops and manufactures advanced systems for public transportation - from passenger information displays and lighting to video surveillance and software solutions for buses, trains, trams, and aviation.

Responsibilities:

• Architect and develop production-grade DVR/NVR software for embedded Linux systems, primarily in Go (other languages considered for strong video/system engineers)
• Design and implement networking modules, storage pipelines, and device-level APIs for reliable, low-latency video capture, secure video streaming, and future AI-driven analytics
• Develop and enforce robust automated testing (unit, integration, hardware-in-the-loop); integrate test frameworks into CI/CD for multiple embedded targets
• Write clear, thorough documentation: design, code, and test plans
• Perform code reviews, mentor developers, and promote engineering excellence across international teams 
• Optimize performance/resource usage (CPU, GPU, memory) to meet real-time and power constraints in embedded environments
• Collaborate with data-science specialists to integrate and optimize computer vision models (object detection, tracking, event identification) – experience nice-to-have, not required
• Support long-term roadmap, exploring advancements in codecs, streaming protocols, and AI/video accelerators
• Be available to work onsite in Münster, Germany couple of days per month

Requirements:

• Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or a related field
• 10+ years’ professional software engineering experience for embedded Linux systems in production
• Advanced proficiency in Go (or comparable system languages) with proven ability in building/debugging multithreaded, networked applications
  Deep knowledge of Linux internals: device drivers, network/IP protocols (TCP/UDP, RTP/RTSP), IPC
• Experience with video streaming technologies and protocols (e.g., H.264/H.265, RTSP, RTMP, DASH, HLS, WebRTC)—designing, building, and debugging secure video transport on resource-constrained devices
• Experience establishing automated test frameworks and CI/CD integration for embedded platforms
• Strong systems architecture mindset: able to balance hardware, software performance, security, and maintainability
• Excellent written/spoken English; comfortable collaborating across distributed teams
• Willingness and ability to travel to Münster, Germany for on-site work couple days per month.

Nice-to-Have Qualifications:

• Video/Codec: Advanced experience with FFmpeg and adaptive bitrate streaming
• AI/Analytics: Integration/optimization of computer vision models for on-device processing (YOLO, OpenVINO, TensorRT, etc).
