Company Description

At 4QT, we electrify heavy machinery without compromising on power or performance. Our patented hybrid-electric drivetrain delivers maximum torque, significantly lower fuel consumption, and reduced emissions, built for the real-world demands of construction. With up to 40% lower fuel consumption, 4QT provides operators and OEMs a pathway to profitability and sustainability without the need for dedicated charging stations. We are engineers, builders, and system thinkers shaping the future of high-power electric motion.

4QT is looking for an engineer specializing in the design, configuration and interfacing of electric systems for hybrid and electric vehicles.

In this role, you will:

• Support the selection and sourcing of key electric components such as motors, inverters, HV batteries, and power electronics.
• Design and implement the HV power distribution system, including configuring high power electric components, wiring, connectors, and layout.
• Configure and commission the electric drivetrain, ensuring seamless integration of all components.
• Assist with system testing, troubleshooting, and performance validation during prototyping and field tests.

Preferred Qualifications:

• Vocational study (Lehre) prior to your studies in any related technical field
• Completed higher studies in Electrical Engineering, Mechatronics, or a related technical field.
• Hands-on experience with electric or hybrid vehicle projects in automotive or heavy machinery (previous work, university projects, student teams, personal projects).
• Familiarity with electric motors, inverters, and power electronics – even at academic or project level.
• Knowledge of high-voltage (400V) safety principles and interest in working with real-world HV systems.
• Basic knowledge of CAN communication and use of diagnostic tools (e.g., PCAN, multimeter, oscilloscope).
• Proficiency in programming languages such as python, C/C++ and Matlab.
• Motivated to learn, proactive, and eager to collaborate with mechanical and electrical teams in a hands-on environment.
