Data Engineer / Data Scientist (Imaging & Data Labelling)

Location:Southwest UK (On-site/Hybrid)

Clearance:Sole British National with active SC Clearance

Engagement:Contract – Outside IR35

Overview:

We are seeking a skilledData Engineer / Data Scientistwith strong experience indata labelling and imaging datasetsto support a critical defence-related project in the Southwest UK. The ideal candidate will have a solid background in building and managing data pipelines, annotating and labelling image-based data for machine learning workflows, and working within secure environments. You will be a key contributor in preparing high-quality datasets to support AI and ML initiatives in a mission-critical context.

Key Responsibilities:

• Develop and maintain robust data pipelines to ingest, clean, transform, and store large volumes of imaging data.
• Lead and support the data labelling process—developing tools and workflows for efficient annotation of image and video data.
