Lead Data Intelligence Machine Learning Engineer

About Us

About The Role

Key Responsibilities

• Architect Labelling Pipelines: Design and deploy end-to-end automated labelling systems using frameworks like Snorkel, Cleanlab, or custom active learning loops.
• Develop "Human-in-the-Loop" (HITL) Systems: Build interfaces and workflows where models pre-label data and humans only intervene on high-uncertainty samples.
• Quality Assurance & Denoising: Implement algorithmic checks to identify and correct mislabelled or "noisy" data within existing datasets.
• Tooling & Integration: Collaborate with software engineers to integrate labelling tools with our existing data lakes and ML training infrastructure.
• Model Optimization: Fine-tune "teacher" models to generate high-quality pseudo-labels for "student" models.
• Set up and maintain robust data preparation infrastructure—optimising for data quality, speed, and seamless integration with downstream MLOps pipelines.
• Perform data visualization and in-depth analysis using advanced data and feature engineering techniques. You’ll help transform raw data into actionable insight, supporting both research and deployment.
• Work closely with Data Scientists, Software Engineers, and Product teams to ensure high data quality and usability across products and projects.
• About you
• At least 8+ years of professional experience in Machine Learning engineering, specifically focused on data centric-AI or computer vision/NLP pipelines.
• Proficiency in Python: Mastery of the Machine Learning stack (PyTorch or TensorFlow, NumPy, Pandas, Scikit-learn).
• Automated Labelling Expertise: Proven experience with Weak Supervision (labelling functions) or Active Learning strategies (uncertainty sampling, diversity sampling).
• Data Engineering: Experience with SQL and NoSQL databases, and managing large-scale unstructured data (images, text, or audio).
• Cloud Infrastructure: Familiarity with AWS (SageMaker Ground Truth), GCP (Vertex AI), or Azure ML labelling services.
• Version Control for Data: Experience with DVC (Data Version Control) or similar tools to track dataset iterations.
• Hands-on expertise building auto-labelling solutions or working with large-scale data annotation workflows.
• Advanced skills in Python (and/or other relevant languages), and experience with key ML/data science libraries (e.g. TensorFlow, PyTorch, scikit-learn, pandas).
• Experience designing, deploying, and maintaining scalable data pipelines, including data cleansing, transformation, and storage (cloud, on-prem, or hybrid).
• Strong background in feature engineering, data analysis, and data visualization—comfortable using tools like Jupyter, Tableau, or Power BI.
• Great communicator who documents solutions clearly and collaborates effortlessly across technical and non-technical teams.
• Able to balance speed and quality, stay curious about new developments, and deliver results in a fast-moving environment.
• Bachelor’s or Masters degree in computer science, Engineering, Mathematics, Data Science, or a related field.
• Dyson is an equal opportunity employer.
• We know that great minds don’t think alike, and it takes all kinds of minds to make our technology so unique.
• We welcome applications from all backgrounds and employment decisions are made without regard to race, colour, religion, national or ethnic origin, sex, sexual orientation, gender identity or expression, age, disability, protected veteran status or other any other dimension of diversity.
