DSP Engineer

As a DSP Engineer 100% (all genders), you will join our global, cross-functional, and highly innovative Smart Sensor Team at our operational headquarters in Nänikon-Greifensee. In this role, you will be responsible for the design, simulation, and validation of signal-processing algorithms that power our industry-leading smart sensors. You will lead the way as the industry transitions into digitalization and smart factories, combining a deep understanding of signal theory and physical systems with practical software development to improve measurement performance and customer value. Your Responsibilities:

• Design and optimize new digital signal processing algorithms for multi-sensor weighing systems (filtering, disturbance compensation, condition monitoring, and noise mitigation) using our modular signal processing platform.
• Analyze and model mechanical, electrical, and physical properties of weighing systems to guide algorithm choices and improve system accuracy and stability.
• Develop proof-of-concepts and conduct performance analyses using MATLAB/Simulink and other simulation tools.
• Collaborate closely with electronics, data science, and firmware teams to ensure seamless integration and product readiness.
• Define and execute test plans, including lab measurements, environmental tests, and field verifications to validate performance under real operating conditions.
• Prepare technical documentation, including requirements, algorithm descriptions, validation reports, and release artifacts.
• Drive innovation by monitoring technology trends, reviewing signal-processing literature, and supporting IP/knowledge capture.

• Master's or PhD degree in Physics, Mechanics, Robotics, Fluid Dynamics, or a related technical field.
• Strong theoretical background in physics, signal theory, and digital signal processing, including control theory, filtering (Kalman, adaptive filters), spectral analysis, system identification, system and noise modeling.
• Proficient in MATLAB and Simulink for system modeling and algorithm development
• Analytical self-starter with a proactive, solution-oriented approach to technical ownership and problem-solving.
• Ability and willingness to work in a global, cross-functional team, including occasional travel for cross-site collaboration and field validation.
• Background in embedded software and knowledge of data acquisition methods are considered strong assets.
• Excellent communication skills in English; ability to explain complex concepts clearly. German language skills are a plus.

• Where applicable flexible working hours, a hybrid work model and a wide portfolio of training opportunities
• 40h week with at least 25 vacation days per year plus 4 to 7 additional days off (i.e. in between bank holidays)
• Free parking spaces and direct access to public transport from our facilities
• Healthy menus cooked onsite and special prices for employees at our own METTLER TOLEDO restaurant
• We offer a dynamic and innovation-driven corporate culture that promotes teamwork, personal development, and a passion for excellence.
• A range of additional attractive benefits like discounts for sport clubs and others
