- Run controlled experiments to evaluate the impact of training strategies, hyperparameter changes, data balancing, and architectural tweaks on model performance.
- Contribute to the development and refinement of false positive filtering pipelines, including ensemble and verification-based approaches.
- Assist with data labelling workflows, quality checks, and dataset preparation for training and evaluation.
- Maintain clear records of experiments, results, and model performance metrics to support reproducibility and team knowledge sharing.
- Perform research into latest AI/ML techniques that bring business value.
- Work on ML Backend development for the production system and support infrastructure.
Requirements
- 2+ Years of experience with Python programming and general Machine Learning.
- Experience with computer vision Deep Learning models.
