Senior Machine Learning Engineer in Bristol

What you will do as a Senior ML Engineer

• Design, build, and optimise machine learning models, including NLP, computer vision, and predictive analytics.
• Own the ML lifecycle from data preparation through training, evaluation, and deployment.
• Implement and maintain MLOps workflows for continuous integration and delivery of ML models.
• Collaborate with Data Engineers and DevOps teams to ensure production readiness and scalability.
• Contribute to architecture decisions for ML pipelines and data flows.
• Apply secure coding and configuration practices in line with compliance standards.
• Mentor junior engineers and share best practices across the team.
• Support innovation by researching emerging ML techniques and tools.

What you’ll bring

• Proven experience developing and deploying machine learning models in production environments.
• Proven experience with the OpenCV framework and various object detection models, including YOLO, RCNN, and Vision models, along with a clear understanding of when to apply each model.
• Proficiency with object detection concepts. Experience in video analysis, particularly optical flow and object tracking.
• Solid knowledge of Optical Character Recognition (OCR) models, with the ability to fine-tune these models using custom datasets.
• An understanding of how to measure the accuracy of text extractions through metrics like Character Error Rate (CER) and Word Error Rate (WER) is also crucial.
• Strong proficiency in Python and ML frameworks (e.g., TensorFlow, PyTorch).
• Understanding of ML architectures, hyperparameter tuning, and performance optimisation.
