• Several years of embedded software experience in motor control, power electronics, or real-time control systems.
• Expert knowledge of C for embedded systems; experience with C++, Python, or scripting tools is beneficial.
• Strong understanding of asynchronous motor-control algorithms, power-converter topologies, and microcontroller architectures (TI C2000, ARM Cortex).
• Familiarity with communication protocols (CAN, TRDP, SPI, I2C) and embedded communication stacks.
• Experience with MATLAB/Simulink for modelling and control-algorithm development is an advantage.
• Fluent in English; German is an advantage.

Responsibilities

• Develop and implement real-time embedded control software for traction and auxiliary converters.
• Program, debug, and optimise embedded firmware in C/C++ for TI C2000, ARM Cortex, and other microcontrollers.
• Design, refine, and validate FOC, vector-control, and sensorless-control algorithms for AC motors in traction applications.
• Integrate CAN, TRDP, SPI, I2C and support system‑level diagnostics and embedded communication handling.
• Use MATLAB/Simulink and other modelling tools to support algorithm development, simulation, and verification.
• Collaborate with system engineers, test engineers, and vehicle control unit software teams for seamless integration.
• Participate in hardware-in-the-loop testing, commissioning, troubleshooting, and continuous improvement.
• Prepare technical documentation and support customer projects requiring deep software expertise.
• Support the training of junior software developers.

At every stage of its operations, the company is committed to ensuring that passengers around the world reach their destinations safely, quickly, and comfortably.

In Poland, Stadler operates several specialized facilities focused on the production of both individual components and complete rail vehicles, as well as their maintenance and servicing.

Stadler has recently decided to expand its power converter factory. The facility will supply converters to Stadler's production sites worldwide, as well as to external customers.

YOUR RESPONSIBILITIES

• Develop and implement real‑time embedded control software for traction and auxiliary converters, focusing on advanced motor‑control algorithms and power‑electronics control.
• Program, debug, and optimise embedded firmware in C/C++ for TI C2000, ARM Cortex, and other microcontroller platforms used in Stadler Converter systems.
• Design, refine, and validate field‑oriented control, vector‑control, and sensorless‑control algorithms for AC motors in traction applications.
• Integrate communication interfaces such as CAN, TRDP, SPI, I2C, and support system‑level diagnostics and embedded communication handling.
• Use MATLAB/Simulink and other modelling tools to support algorithm development, simulation, and verification activities.
• Collaborate closely with system engineers, test engineers, and vehicle control unit software development team to ensure seamless integration of software with converter hardware and control architecture.
• Participate in hardware‑in‑the‑loop testing, commissioning, troubleshooting, and continuous improvement of converter‑control software.
• Work in line with STACON processes and contribute to their optimization
• Prepare technical documentation, contribute to design reviews, and support customer projects where deep software expertise is required.
• Support the training of junior software developers through knowledge transfer

OUR REQUIREMENTS

• Degree in Control Engineering, Computer Engineering, Embedded Systems, Electrical Engineering, or a related discipline.
• Several years of experience in embedded software development for motor control, power electronics, or real‑time control systems. Strong alignment with traction‑converter or industrial‑drive applications is a plus.
• Expert knowledge of C for embedded systems; experience with C++, Python, or scripting tools is beneficial.
• Strong understanding of asynchronous motor ‑control algorithms, power‑converter topologies, and microcontroller architectures (TI C2000, ARM Cortex).
• Familiarity with communication protocols (CAN, TRDP, SPI, I2C) and embedded communication stacks.
• Experience with MATLAB/Simulink for modelling and control‑algorithm development is an advantage.
• Ability to read and understand electrical diagrams and perform software‑related measurements on converter hardware.
• Fluent in English.
• German is an advantage.

YOUR BENEFITS

• Enjoy stable, long‑term employment based on a full employment contract.
• Benefit from flexible working hours with a convenient start window between 7:15 and 9:00.
• Take part in a wide range of development projects that offer real opportunities to grow and expand your expertise.
• Access an attractive benefits package, including private medical care, a lunch card, a sports card, holiday subsidies and Christmas vouchers.
• Participate in company integration events held twice a year, strengthening teamwork and collaboration.
