Expected

• C
• C++

Your responsibilities

• Development of embedded and real-time software architectures for MW-scale converters/inverters.
• Definition of software architecture, task scheduling, and interfaces for converter/inverter control platforms.
• Implementation of control algorithms (inner current loops, outer voltage and power functions) in close collaboration with control engineering.
• Support definition of converter/inverter topology, control realization, and system integration approach for the company’s new products.
• Implementation of state machines, fault handling, protection mechanisms, and diagnostics.
• Optimization of software for real-time performance, determinism, numerical robustness, and reliability.
• Implementation and maintenance of communication interfaces (e.g., CAN, EtherCAT, Ethernet, SPI, UART).
• Support of grid code requirements (LVRT/HVRT, fault ride-through, reactive power support) through software implementation.
• Validation through SIL, HIL, and support during prototype bring-up, commissioning, and field testing.
• Close collaboration with system, control, hardware, and test teams to optimize performance, robustness, and scalability.

Our requirements

• BS degree in Electrical/ Computer Engineering required. Post-graduate technical degree desired.
• Greater than 5 years in related field required, including post-graduate experience.
• Strong knowledge of embedded software development for power electronics systems.
• Proven experience with MW-scale converter/inverter platforms.
• Solid understanding of control theory implementation for power converters (current, voltage, power, DC-link control).
• Experience with real-time systems, scheduling, interrupts, and timing constraints.
• Knowledge of digital control implementation effects (sampling, delays, discretization, numerical limits).
• Proficiency in C/C++ for embedded and real-time applications.
• Experience with DSPs, MCUs, or SoCs used in high-power converter control.
• Familiarity with communication protocols and industrial fieldbuses.
• Experience with SIL, HIL, and system-level testing.
• Understanding of grid-connected converter behavior and grid code requirements.
• Ability to define software architecture and integration approaches for complex converter systems.
• Strong system-level thinking and cross-functional collaboration skills.
