SW Control Engineer - Power Electronics | Automotive | Prague / Hybrid

🚀 We’re Hiring:

We are KOSTAL Engineering s.r.o , an established R&D-focused engineering company specializing in the development of automotive electronic control units. Our Prague-based team works on power electronics systems, including On-Board Chargers (OBC, 7.2–22 kW) and DC/DC converters .

We are seeking a Control-Loop Software Engineer to design and develop control systems for power electronics applications such as power factor correction (PFC) stages and DAB-based DC/DC converters. You will work across the full development cycle—from modeling and simulation to validation —with the opportunity to take full end-to-end ownership, including hands-on testing on real hardware .

🔧 What You’ll Do

• Develop and refine mathematical models of power electronic converters for model-based control design
• Design, implement and optimize digital control algorithms for PFC and DC/DC systems
• Perform simulation and analysis of closed-loop control systems using MATLAB and Simulink
• Evaluate system robustness and dynamic performance (e.g., frequency response, stability margins)
• Support experimental validation on hardware in the lab when applicable
• Own and drive full control loop development, with the opportunity to grow into end-to-end ownership

🎯 What We’re Looking For

• Strong understanding of control theory and feedback systems
• Familiarity with MATLAB / Simulink
• Understanding of analog circuits and analysis methods
• Experience with embedded C/C++ programming

⭐ Preferred Skills (Nice to Have)

• Basic knowledge of electronic circuits (e.g. SMPS, PFC concepts),
• Experience with digital control and embedded systems
• Interest in bridging modeling, control design, and real hardware behavior
• Familiarity with tools such as PLECS, SPICE-based tools, TPT, or MXAM

⚡ What You’ll Get

• R&D-focused environment within an established engineering company
• Responsibility for full control loop development
• Work on real automotive power electronics systems (OBC and DC/DC converters)
• Opportunity to test and validate control designs on real hardware
• Hybrid work setup based in Prague, with flexibility

🎁 Benefits

• Flexible working hours and strong work–life balance
• 5 weeks of annual leave
• Retirement savings contribution
• Recognition of seniority and experience
• Meal allowance
• MultiSport card
• Covered parking (car / motorbike / bicycle)
• Regular healthy breakfasts and team events
• Free hot and cold beverages in the office
• Bicycle shower facilities
