Aftermarket Senior Software Engineer – Frequency converters
Position purpose
The Software Engineer, reports to the Engineering Manager. This position works under a low level of supervision with a high level of independent work.
As a Software Engineer, you will focus on the architecture, development, and reliability of embedded and real-time software for high-power, grid-connected converters and inverters.
You will be responsible for software concepts from the early system definition stage through validation and field deployment, working at the intersection of control systems, power electronics, system engineering, and embedded platforms.
Your Tasks
- 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.
Other Functions
- Provides technical mentorship to junior software engineers and supports growth of the software engineering team.
- Defines software interfaces and integration concepts with embedded hardware platforms.
- Contributes to intellectual property creation (patents, technical disclosures).
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.
