Control Strategy Developer / Control Strategy Developeress

Johnson Electric International AG Murten September 22, 2026

GENERAL MISSION

We are seeking a talented professional to develop model-based design (MBD) control strategies for thermal system management. This role focuses on optimizing compressor capacity modulation, mode switching, and energy efficiency through advanced algorithms and real-time vehicle integration.

KEY RESPONSIBILITIES

  • Develop MATLAB/Simulink control system models and algorithms.
  • Design compressor capacity modulation strategies for optimal cooling and heating.
  • Optimize mode switching logic (cooling ↔ heating ↔ defrost).
  • Manage energy for electric vehicles, specifically battery thermal conditioning.
  • Conduct model-in-the-loop (MIL) and hardware-in-the-loop (HIL) validation.
  • Integrate control algorithms with vehicle embedded software (CAN communication).
  • Collaborate with test engineers for SIL/HIL validation.
  • Evaluate AI/ML approaches for intelligent thermal management in future roadmaps.

EDUCATION & QUALIFICATIONS

Minimum: Master's degree in Control Engineering, Electrical Engineering, Mechanical Engineering, or a related field.

University Quality: 8-10/10 (a strong algorithmic and research background is highly valued).

Specialization: Control Systems, Model-Based Design, Embedded Systems, with Machine Learning as an optional focus. A PhD is advantageous as it demonstrates research depth and complex problem-solving capability.

EXPERIENCE REQUIREMENTS

Years: 5-7+ years in automotive control systems or embedded software development.

Background: At least 2 major projects related to thermal or powertrain control utilizing MATLAB/Simulink.

Technical Focus: Control algorithm development, SIL/HIL validation, and vehicle-level software integration.

OEM or Tier 1 Experience: Experience with companies such as Bosch, Continental, Marelli, VW/Audi electronics, or equivalent is preferred.
