Machine Learning Engineer with Sensor Background

In this role, your primary focus will be designing, building, and deploying production-grade machine learning models that extract actionable insights from noisy, and multi-modal sensor data. Your key responsibilities will include:

• Model Development: Designing, training, and evaluating classical ML and deep learning architectures (e.g., CNNs, RNNs/LSTMs, Transformers) optimized for time-series forecasting, anomaly detection, gesture recognition, or spatial tracking.
• Advanced Architecture Design: Building and fine-tuning state-of-the-art Transformer-based models and Large Language Models (LLMs) adapted for sequential data (e.g., Time-Series Transformers, behavioral embeddings, and tokenized sensor streams).
• Signal Processing & Feature Engineering: Implementing digital signal processing (DSP) techniques; including filtering, windowing, fast Fourier transforms (FFT). To clean, calibrate raw, noisy sensor data and extract robust features.
• Edge & Embedded Optimization: Optimizing models for resource-constrained environments via quantization, pruning, and hardware-accelerated compilation (e.g., ONNX, TensorRT, TensorFlow Lite) for deployment on edge devices.
• ML Operations & Data Pipelines: Building scalable pipelines capable of handling massive volumes of streaming, asynchronous telemetry data, ensuring minimal latency and high throughput in production.
• Experiment & evaluation of sensors in various environments such as microphone, accelerometer, gyroscope, ultrasonic time of flight, pressure, magnetometer.
• Development: oversees product development, data collection, improvement and testing.
• Reporting: communicate complex technical information and analysis to extended team members and management.

At TDK we foster a collaborative and supportive engineering and business culture. Especially, as our algorithms are - an important but only a part - of the solution, collaboration between algorithm team, machine learning team, integration team, validation team and HW team is key to understand the system. Therefore, your ability to demonstrate excellent communication skills is critical as you interact with engineers from other teams (system, validation, embedded software development, and marketing), partners, and suppliers. In doing so, you will enjoy the opportunity to be visible and measurably contribute to the advancement of our technology and product lines., * MSc/Ph.D. in Computer Science, Signal Processing, Machine Learning (ML),
