Senior Product Owner (m/f/d) - FlixTrain Tech Stream at Flix

At Flix, we offer a tech-driven environment where innovation meets real-world impact, with competitive pay, strong growth opportunities, and a culture of collaboration and ownership.  We’re looking for a motivated and driven Senior Product Owner who will help us shape team Pantograph as part of FlixTrain Tech organization. FlixTrain has ordered Talgo 230 trains with delivery starting in 2028. To operate these trains legally in the EU, we must successfully complete TSI-compliant train homologation. This includes certifying and integrating several train-side systems (Passenger Information, Telemetry & Diagnostics, CCTV, Onboard Unit, etc.) with Flix wayside systems. To meet a tight feature-freeze window on the train side and enable end‑to‑end tests, we are forming a dedicated integration team. This team will build and operate critical middleware and integrations (e.g. mTLS Proxy, VPN, MQTT messaging, certificate management, telemetry & diagnostics flows) between the trains and Flix’s backend landscape. If you enjoy complex technical projects, hard deadlines, and driving alignment across multiple internal and external partners, this is a unique opportunity to shape the future of train mobility at Flix. After the 2026 integration and testing deadlines are met, the team will shift from a project-style, integration‑heavy focus towards ongoing product development. The same platforms we build now for end‑to‑end tests will become the core product surface that powers future fleet operations. About the Role • Define and drive the product vision for FlixTrain’s train‑to‑backend integration layer • Own and refine a highly technical backlog, covering areas such as mTLS proxying, VPN connectivity, MQTT messaging, certificate lifecycle automation, and data ingestion flows • Coordinate with other Product Owners on cross‑team capabilities, shared roadmaps, and interface alignment across Flix’s wider mobility and operational ecosystem • Lead cross‑organization integration work with train manufacturers, subsystem vendors, and internal platform teams, ensuring structured risk management process • Balance speed of delivery with engineering quality and maintainable solutions • Make data-driven decisions to continuously optimize product outcomes About You • 3–5 years of experience as a Product Owner, with solid project management skills and a demonstrated ability to collaborate successfully with cross-functional product teams • You bring strong technical understanding that enables meaningful discussions with engineers on APIs, messaging, networking, security (certificates, authentication/authorization), observability, and cloud infrastructure, with the ability to assess implications for scope, risks, and timelines • You bring ownership, curiosity and a positive attitude to a high‑stakes, complex environment • Deep understanding of Agile software product development principles and techniques, including User Story Mapping, Impact Mapping, Lean, and Design Thinking, with a proven ability to apply them to drive product vision, prioritize work, and deliver customer value effectively • You enjoy working in an international environment and across organizational boundaries • Experience working with external vendors / partners on technical integrations is a strong plus • Fluent in English We recognize that everyone carries a unique set of valuable skills and experiences. If you think you could have an impact even though you don't meet 100% of the requirements, we still encourage you to apply.
