• Lead and supervise the marine acoustic data labelling process, ensuring the quality, consistency, and traceability of labelled datasets.
• Lead and supervise the marine visual data labelling process, ensuring the quality, consistency, and traceability of labelled datasets.
• Coordinate, train, and support students and part-time labellers, including task allocation, technical guidance, and quality monitoring.
• Define, document, and continuously improve annotation protocols, categories, criteria, and workflows.
• Review and validate annotations, resolve ambiguous acoustic events, and monitor inter-annotator agreement.
• Annotate and validate marine acoustic data, including cetacean vocalisations and other biological, environmental, and anthropogenic sound sources.
• Annotate and validate marine visual data, including fish, cetacean and reptiles.
• Work with the AI team to prepare and assess training, validation, and test datasets for underwater sound&vision detection and classification algorithms.
• Ensure appropriate organisation and traceability of recordings/images, annotations, metadata, and dataset versions.
• Contribute to the continuous improvement and automation of labelling, quality-control, and human-in-the-loop workflows.
• Report on labelling progress, dataset quality, limitations, and data requirements to the AI team.

Expertise Needed

• Degree in Marine Biology, Bioacoustics, Marine Science, Biology, Ecology, Acoustic Engineering, Computational Vision, or a related field.
• Practical experience in marine bioacoustic data annotation and analysis, including cetacean vocalisations and spectrogram interpretation.
• Hands-on experience with acoustic annotation tools such as Raven Pro, PAMGuard, Audacity, Triton, Kaleidoscope, or equivalent.
• Experience or demonstrated ability to coordinate, train, and supervise labellers and ensure annotation quality.
• Understanding of how labelled datasets are used for AI/ML training, validation, and testing.
• Strong organisational and communication skills, with good written and spoken English.
• Authorisation to work in Portugal.

Added Value (Two of Any of These Skills Are Needed)

• Knowledge of audio formats, sampling rates, hydrophone calibration, acoustic metadata, and annotation protocols.
• Experience with AI model evaluation, human-in-the-loop/active-learning workflows, or annotation quality control.
• Experience/knowledge with AI/ML.
• Experience/knowledge with Computer Vision.
• Experience/knowledge of field sensorization and ocean campaigns.
• Basic knowledge of Linux.
• Basic knowledge of Git.
• Experience coordinating annotation teams or contributing to national or European research projects.
