Senior Power Electronics Embedded Software Engineer

Flex

Stuttgart, Germany

Job Summary:

To support our extraordinary teams who build great products and contribute to our growth, we’re looking to add a passionate & problem solving Senior Power Electronics Embedded Software Engineer (m/f/d), ideally located in Stuttgart, Germany.

Reporting to the VP Power Electronics, the Senior Power Electronics Embedded Software Engineer (m/f/d) role will be responsible to drive technical development of high & low voltage AC and DC power electronics ECUs based on latest MCU platforms in automotive environment and design software architecture for power electronics products such as OBC, HV DC/DC Converters and HV Inverters.

What a typical day looks like:

Provide overview of development roadmap and make architectural decisions with the team regarding Hardware/Schematics/Layout topics which relate to MCU/Software, and give input to Hardware, System & Functional Safety teams;
Execute code reviews and document software architecture & designs in UML tools such as Enterprise Architect;
Lead functionally software teams and closely collaborate with other engineering functions (e.g., hardware and mechanical department);
Describe architecture designs using several views which include:
- a static view showing the code structure of the system;
- a dynamic view showing the actions of the system during execution.
and a deployment view showing how a system is placed on hardware for execution;
Drive continuous improvement of team collaboration & ways of working.

The experience we’re looking to add to our team:

A completed degree in a related discipline - preferably Computer Science or Electronics including vast experience with Embedded Systems:
- Clean design of C modules, understanding of interfaces & structuring of header includes, perfectionistic demand for “beauty of the code”;
- Full understanding of the entire chain from high-level C code, through compiler, linker, optimizations, down to machine code (assembler) and the CPU actions at register level: memory load/store, caching;
- Linker scripts, understanding benefits of mapping to specific memory regions.
Good Understanding of electronics hardware, especially power electronics:
- Methods for optimizing efficience and high voltage experience;
- Laboratory work: hands-on analysis of system behavior, current vs voltage, troubleshooting, soldering, oscilloscopes, behavior of electrical voltage sources and loads and signal filtering (in HW vs SW).
Control loops (PID controller, preferably more types);
Knowledge of common automotive microcontrollers at register level (low level, driver):
- Common analog digital converter types;
- Evaluation with/without DMA;
- PWM modulation.
Operating systems, schedulers, interrupt handling.
