FlixTrain is seeking a Network Engineer to own the on-board technology ecosystem that defines how passengers connect, navigate, and experience every journey. You will be responsible for WLAN, network infrastructure, on-board units, and mobile devices for train staff—technologies that are becoming critical differentiators in rail as connectivity reshapes the industry.
In this role, you will:
• Own the entire on-board technology ecosystem (WLAN, networks, on-board units, mobile devices) and continuously push beyond the status quo
• Serve as the central technical authority for all on-board systems, evaluating specifications, weighing trade-offs, and making well-reasoned decisions
• Monitor on-board technology performance continuously, identify issues early, and drive improvements that make every journey smoother
• Lead cross-functional projects around connectivity, network performance, and mobile device integration into the fleet independently and with clear impact focus
• Define technical specifications and network architectures that are both ambitious and implementable, ensuring seamless integration with the vehicle fleet
• Develop test scenarios and functional validations—especially at critical customer and certification touchpoints—to ensure solutions work in real operations
• Monitor emerging technologies (5G, IoT, Starlink) and translate insights into concrete recommendations for FlixTrain's technology roadmap
You will work closely with Operations, Customer Product, FlixTech, and external partners including Talgo, ECMs, and suppliers (e.g., Icomera, Advantech).
REQUIREMENTS:
• Bachelor's or Master's degree in Telecommunications, Computer Science, Electrical Engineering, or related field
• 2+ years of practical experience in network architecture, WLAN systems, or Mobile Device Management, ideally in rail vehicles or similarly complex technical environments
• Strong problem-solving skills and demonstrated experience troubleshooting complex network systems under time pressure
• Willingness to take ownership: you drive topics to completion independently and lead cross-functional initiatives across teams and disciplines confidently
• Clear and persuasive communication with both technical experts and non-technical stakeholders, without sacrificing precision
• Fluent German and English (negotiation-level proficiency), as you will work in an international team and with German-speaking suppliers and regulatory bodies
• Advantageous: experience with rail vehicle system suppliers and familiarity with the contractual, technical, and regulatory environment of the rail industry
