- Play a key role in defining system architecture for the ML products and implementing specific components to enhance the user experience.
- Design and implement performant, scalable ELT (Extract, Load, Transform) data pipelines, considering an ML model's lifecycle (training and inference).
- Take responsibility for technical problem solving and meeting ML product objectives creatively in ambiguous scenarios.
- Participate in the on-call rotation for production support.
- Drive best practices including ML research methodologies, coding standards, code reviews, source control management, development processes, build processes, testing and release, and operational excellence.
Requirements
- Advanced degree in computer science, data science, machine learning, or related field, or equivalent work experience.
- 6+ years of professional experience in software engineering designing and building ML-driven products, with at least 3 years focused on production ML systems.
- Fundamental knowledge of Data Engineering and extensive experience in developing and deploying ML models, as well as building and maintaining ML pipelines and products.
- Experience in applying scientific method: hypothesis formulation and testing, exploratory data analysis, cross-validation, reproducible research, and structured reporting/documentation, result explanation and presentation.
- Experience designing, deploying, and operating scalable ML systems in production. This includes responsibility for model selection, performance benchmarking, and lifecycle management to solve real-world business problems.
- Proficiency in Python and general ML ecosystem tooling in data processing and modelling (such as NumPy, Pandas, Scikit-learn, PyTorch, etc.).
- Experience in designing and building products using public cloud services such as AWS.
- Excellent verbal and written communication skills in English, and ability to convey research findings and implications to both technical and non-technical audiences.
- Ability to work effectively in cross-functional and distributed teams across different time zones.
