Job Description and Responsibilities:

Fraunhofer Portugal AICOSis seeking a talented Junior Privacy-Preserving ML Scientist to join our dynamic and multidisciplinary team within the Intelligent Systems group. In this role, you will be at the forefront of technological innovation, working on applied research projects that bridge the gap between cutting-edge research and real-world impact. You will contribute to initiatives that enhance industries, promote social well-being, and improve quality of life. Specifically, you will contribute to the research and development of methodologies to improve the privacy and robustness of ML models. You will also contribute for testing a flexible distributed software framework, which includes federated learning and data governance to support the deployment of privacy-preserving ML pipelines.

 

Your role:

- Research and develop on collaborative, privacy-preserving and responsible ML in development of computer vison models for image classification, and validation of model evolution;

- Reuse existing federated learning infrastructure, a privacy preserving machine learning approach that enables data scientists and ML engineers to train models without moving the data;

- Train an existing model with more private data, including data diversity assessment and model robustness evaluation to detect weaknesses:

>  Apply transparent reporting mechanisms, such as data and model cards, to communicate findings effectively and guide decision-making;

> Evaluate the utility of data augmentation with generative AI (using existing models at Fraunhofer).

- Work closely with multidisciplinary teams to integrate into existing processes:

> Maintain and refine current codebases, adhering to best practices in software development and reproducible research;

> Contribute to strategic discussions on advancing research directions, staying updated on cutting-edge ML methods related to privacy-preserving and responsible ML methodologies.

 

Your profile:

 

Academic Qualifications:

- Master’s degree or equivalent qualifications in Biomedical Engineering, Computer Science and Engineering, Electrical and Computer Engineering, Artificial Intelligence, or related studies.
