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

You can expect challenging, interesting, and varied tasks in an innovative and international environment, with the opportunity to network globally and realize your next career goal.
