ML Data Engineer (m/f/d) - Sensor Data & Pipelines

What we offer

• Work in an international, agile team creating the future of autonomous systems


• Grow your career in a expanding and ambitious engineering team


• Build innovative products using state\-of\-the\-art technologies in AI, robotics, and autonomy


• Benefit from a steep learning curve and continuous development


• Enjoy team events and a strong, collaborative culture

Your mission

This role sits at the core of our perception systems, owning the data that directly drives model performance in real\-world environments. You will work closely with ML, perception, and robotics teams, focusing on building, curating, and continuously improving datasets behind object detection — turning raw sensor data into reliable, high\-performing systems.

You will take end\-to\-end ownership of the ML data lifecycle, from data collection and ingestion to labeling, quality assurance, and continuous dataset improvement, ensuring data is representative, high\-quality, and production\-ready.

What you'll do:

• Design and maintain scalable pipelines to ingest, organize, and preprocess large volumes of time\-series camera and multi\-sensor data (RGB, IR, thermal, depth, IMU)


• Own and continuously improve object detection datasets, ensuring quality, diversity, and statistical representativeness


• Build and operate active learning loops, connecting model performance with data selection and improvement


• Manage labeling workflows end\-to\-end, including tooling, QA validation, consistency checks, and coordination of annotation efforts


• Collaborate with ML Engineers to evaluate models and translate weaknesses, bias, and drift into actionable dataset improvements


• Plan and execute data collection campaigns (e.g. field recordings, drone/video capture) to acquire high\-value real\-world data


• Create internal tools and dashboards to analyze dataset quality, distributions, and performance gaps

Your profile

• Strong experience in Python and data processing frameworks (Pandas, NumPy, vectorized operations, multiprocessing).


• Hands\-on experience building ETL/ELT pipelines for ingesting, transforming, and structuring large video and sensor datasets.


• Experience with data orchestration and lifecycle management for ML and computer vision workflows, including dataset versioning and reproducibility.


• Solid understanding of object detection pipelines (Detectron2, MMDetection, COCO format, bounding\-box standards).


• Experience with active learning, uncertainty sampling, or semi\-supervised dataset workflows.


• Familiarity with data annotation platforms (CVAT, Label Studio) and automated QA/consistency checks.


• Strong grasp of evaluation metrics for object detection (IoU, mAP, precision\-recall curves, class\-wise metrics).


• Comfortable with databases (SQL/NoSQL), file systems, and the management of large\-scale image, video, and sensor datasets.


• Ability to work cross\-functionally with perception, deployment, robotics, and data infrastructure teams.


• Fluent in English, German and/or French are a plus

Nice to have

• Experience with cloud storage and MLOps tools (AWS S3, MinIO, ClearML, MLFlow, Weights \& Biases).


• Familiarity with ROS / robotics data formats (bag files, TF trees, sensor\_msgs), Docker, or embedded ML workflows.


• Prior work with robotics, drones, or multi\-sensor perception systems, including IR, LiDAR, radar, or audio datasets.

What else

• 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.

Why us?

Join us to shape the future of AI\-driven defense!

About us

The world is changing. Exponential technologies are enabling new types of security threats. ATS is committed to staying ahead by building nimble, scalable, and cost\-effective defences. We are looking for passionate team members who are eager to create exceptional products, safeguard our freedom, and strengthen the resilience of democracies.
