Embedded Linux Cybersecurity Developer

Embedded Software Engineer

We don't just develop embedded software — we engineer intelligence into products. The Embedded Competence Center at NTT DATA Romania brings together experts in embedded systems, firmware development, and hardware–software integration, delivering robust and high-performance solutions for complex, safety-critical environments. With strong expertise in C/C++, AUTOSAR, real-time operating systems, and communication protocols, we design scalable embedded architectures, integrate software seamlessly with hardware, and ensure compliance with industry standards. Across the industries we support — from Automotive and Industrial Automation to Smart Devices and IoT — we transform reliable embedded technology into a foundation for innovative, dependable products. You will be part of the development of an advanced telematics solution for commercial vehicles. You will join feature teams, working in an Agile environment (SAFe framework), contributing to the delivery of features within Program Increments (12-week cycles). This role is well suited for freelancers or independent consultants looking to work on complex automotive embedded projects.
