As an AI/ML Senior Data Scientist, you will work with Pie’s data science, data/ML engineering, and product teams to conceptualize, build and enhance data-driven AI/ML solutions to address business challenges–having the opportunity to immediately impact various business functions through your efforts. As Senior Data Scientist, you will also get to explore the frontiers of deep-learning, Natural Language Processing/Generative AI, along with supervised/ unsupervised/semi-supervised ML algorithms to build more elegant ML solutions, engineer novel features, and construct automated capabilities. Ultimately, you will help ensure that using AI/ML is key to how we operate, and as easy as Pie.

How You’ll Do It

Working collaboratively with our Product, Data Engineering and MLOps teams, you will be actively involved in the entire Model Development Life Cycle from conceptualization to deployment. You will help conceptualize, design, generate and test hypotheses, construct features, build and validate models–leveraging your deep-learning and NLP skills to develop language-based features, build semantic indexing, construct domain-specific corpus, fine-tune pre-trained models, and build foundation and/or generative ML solutions.

The Ideal Candidate Will Be Able to -

• Understand analytics & modeling needs; build validated data pipelines to extract internal and external data, conduct exploratory analysis
• Build new high-signal features; build, strengthen, and validate robust AI/ML solutions
• Develop and implement feature engineering strategies to extract meaningful features from raw structured data and text-based data to optimize model performance
• Conceptualize, prototype, and implement Generative and Augmented AI solutions, leveraging LLM, Image processing, and deep-learning capabilities
• Work with both data engineering and analytics teams to find useful data sources; ensure data quality and consistency
