ML Data Engineer - Object Detection & Active Learning (m/f/d)

Your mission

• Design and maintain scalable pipelines to ingest and organize large volumes of time-series camera and sensor data (RGB, IR, acoustic, depth, IMU, and other modalities).
• Own and improve datasets for object detection and classification tasks, ensuring statistical robustness, diversity, and representativeness.
• Build and operate active learning loops to select high-value samples, reduce annotation cost, and continuously improve model performance.
• Write robust preprocessing pipelines using Python, NumPy, Pandas, and augmentation libraries like Albumentations.
• Manage labeling workflows, including QA rules, label consistency checks, vendor coordination, and dataset versioning.
• Collaborate with ML Engineers to fine-tune, train, and evaluate object detection models and feed insights back into the data pipeline.
• Analyze model weaknesses, uncover blind spots, and drive dataset improvements through statistical diagnostics and drift/bias detection.
• Create internal tools to visualize, audit, and analyze dataset quality, diversity, long-tail performance, and failure modes.

Your profile

• Strong experience with Python and data-processing frameworks (Pandas, NumPy, multiprocessing).
• Familiarity with ETL/ELT pipelines for ingesting, transforming, cleaning, and structuring large video or sensor datasets.
• Experience with data orchestration and lifecycle management for ML workflows (preferably with high-bandwidth video/sensor workloads).
• Understanding of object detection pipelines and formats (COCO, Detectron2, MMDetection, label schemas).
• Experience with active learning, uncertainty sampling, or semi-supervised labeling workflows.
• Familiarity with annotation tools (CVAT, Label Studio) and quality-assurance processes.
• Solid understanding of model evaluation metrics (IoU, mAP, precision-recall, confusion matrix).
• Comfortable working with databases (SQL/NoSQL), file systems, and large-scale image/video dataset organization.
• Ability to collaborate effectively with perception, deployment, and robotics engineers across the product lifecycle.
• Fluent in English, German and/or French are a plus.

Nice to Have:

• Experience with cloud storage systems and MLOps platforms (AWS S3, MinIO, MLFlow, ClearML, Weights & Biases).
• Familiarity with ROS / robotics data formats (bag files, TF trees, sensor_msgs), Docker, or embedded ML stacks.
• Prior work with drone, robotics, or sensor-rich environments, including IR, LiDAR, radar, depth, or audio systems.

Meta:

• Outside-the-box creativity with a blend of conceptual and systematic design thinking.
• High intrinsic motivation, attention to detail, and strong problem-solving mindset.
• Structured, methodical, and reliable execution, even under uncertainty.
• Humble, collaborative, and mission-driven — values collective success over ego.
• High ethical standards and disciplined work ethic.
• Extra-curricular achievements, leadership, or unique projects are a plus.
• NATO-aligned nationality or close ally citizenship is required.
• Successful candidates must obtain security clearance.
