E-Bike Software Developer - Motor Functions (m/f/d) | 100% | Cham, Switzerland

Job Summary

To strengthen our eBike development team in Cham, Switzerland, we are seeking a E-Bike Software Developer - Motor Functions to commence immediately or by agreement.

In this role, you will be responsible for the design, development, and validation of motor related application and functions that define system behavior and rider experience. The position focuses on application logic, functional behavior, and system interaction rather than low level motor control algorithm development.

You will apply deep software expertise combined with strong physical system understanding to create robust, well validated motor functions across bench, system, and bike level.

Internally, you will work closely with Ride Control, System Engineering, Software and Quality teams. Externally, you will have a chance to collaborate with motor suppliers on application and integration topics.

How You’ll Make a Difference

Motor Functions Development

• Develop and own motor application functions (assist and torque behaviour, functional limits and protections, derating and thermal strategies, system dependent motor behaviour, determining and setting right gear, etc.)
• Translate rider experience goals and system requirements into clear, testable functions
Own motor functions across the full development lifecycle (concept implementation calibration
• validation)

Advanced Modeling, Simulation

• Analyze system and motor behavior to design and validate robust functions
• Use data from testing to evaluate interactions, limits, and improvements

Application-Level Software Development

• Develop and implement motor functions
• Work confidently and independently in C, C++, knowledge of Zephyr OS is a plus
• Debug multi‑layer behaviour across software, hardware, and system boundaries

Testing, Validation & Field Support

• Help to define and execute application-level test cases for motor functions
• Support bench, system, and bike-level testing activities
• Analyse issues using data-driven methods and physical system understanding

Cross Functional & Supplier Collaboration

• Act as a technical expert for motor application and function topics
• Align functional behaviours within mechanical, electrical, and system constraints
• Continuously improve development, validation, and release processes
• Go out, ride, observe system behaviour, and feed insights back into development

What You’ll Need to Win

Education & Experience

• Bachelor’s, Master’s degree in Mechatronics, Electrical Engineering, Mechanical Engineering, Systems Engineering, or similar
• 3+ years of relevant experience in application development, system functions, or embedded systems (seniority implied by tool expectations)

Required Technical Expertise

• Expert level proficiency in: Python, MATLAB, Simulink, C
• Experience with modern programming languages such as: C++17 and up, Rust, Zig
• knowledge of Zephyr OS is a plus
• Strong understanding of physical systems and their behaviour
• Proven experience developing application-level embedded software
• Confident handling of:
  • CAN communication, protocols, and diagnostic tools
  • Git version control
  • debugging across system boundaries

• Strong system thinker with a structured, analytical mindset
• Comfortable bridging physical behavior, software logic, and real-world testing
• Able to work independently on complex topics and drive them to completion
• Clear and effective communicator in cross functional, international teams

Language & Mobility

• Excellent English skills (written and spoken), German is a plus
• Willingness to travel occasionally (approx. 10%)

Nice to Haves

• Experience with eBike, automotive, or electrified drive systems
• Experience supporting products into series production
• Familiarity with system identification or model-based development (Control theory)
• Passion for cycling
