Job Description

Who We Are

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.

We're looking for an experienced Hardware Design Engineer to join our team. In this role, you will be responsible for the end-to-end hardware development of High Voltage Battery Management Systems (HV BMS), including schematic design, circuit simulation, validation, testing, technical documentation, and close collaboration with customers and cross-functional teams. We welcome applications from both permanent employees and freelance professionals with relevant expertise in automotive hardware development.

What you'll be doing

• Performing development tasks based on existing hardware specifications and architectures
• Creating/updating and validating(worst case calculation & simulation) circuit diagrams
• Writing test specifications and performing hardware electrical test on development samples
• Performing process documentation(planning, module docu., layout requirements, FMEA)
• Support technical knowledge sharing and provide guidance to less experienced engineers when required.

What you'll bring along

• Bachelor's or Master's degree in Computer Science, Electronics, Embedded Systems, or a related engineering field.
• Minimum 5 years of relevant experience in HW development
• Strong knowledge of analog and digital hardware design for automotive applications.
• Experience with High Voltage Battery Management Systems (HV BMS) and Li-Ion battery technologies.
• Good understanding of Functional Safety (ISO 26262) requirements and their implementation in hardware development.
• Knowledge of EMC/EMI design principles and hardware robustness requirements.
• Experience in hardware reliability analysis and FMEA.
• Familiarity with electrical simulation tools such as LTspice, PSpice, or equivalent.
• Strong problem-solving and analytical skills.
• Ability to communicate effectively with customers and cross-functional teams in an international environmen
