• Contribute to IMDEX’s Nexus ML platform, including reusable tools, templates and CI/CD integration.
• Collaborate with Geo-Data Scientists, Product Managers and Software Engineers across discovery, development and release.
• Conduct experiments, benchmarking, model evaluation and error analysis using robust validation practices.
• Identify opportunities to improve model performance, delivery efficiency, maintainability and technical quality.
• Contribute to feasibility assessments, technical scoping, estimation, documentation and demonstrations.
• Communicate progress, risks, blockers and dependencies clearly to technical and project stakeholders.
• Take ownership of commitments, work collaboratively, seek feedback and constructively address issues.

To be successful

• Bachelor’s degree (or equivalent experience) in Computer Science, Data Science, or a related field.
• Proficiency in Python with demonstrated experience writing production-grade code.
• Exposure to ML frameworks such as PyTorch, TensorFlow, scikit-learn, and pandas.
• Understanding of ML lifecycle management, validation, and performance monitoring.
• Experience working in cloud or containerised environments (e.g., Docker, CI/CD pipelines).
• Strong collaboration and communication skills within multidisciplinary teams.
• Experience with MLOps tooling (model registry, automated evaluation, drift monitoring).
• Understanding of geoscience or spatial data.
• Experience contributing to documentation, playbooks, or internal enablement materials.
