No other bank is doing what we do.
At BDC, we’re devoted to Canadian entrepreneurs. We’re also dedicated to our employees. Adaptable. Inspiring. Different. There’s a reason we like to work here and we think you’ll like it too.
BDC is looking for bright, knowledgeable and motivated Senior Data Scientists experienced with the state-of-the-art (SOTA) Machine Learning (ML), Deep Learning (DL), and big data architectures.
As a Senior Data Scientist, you will be working within the AAAI team and contribute to enterprise-wide best practices, processes
The bulk of the work will be in framing the problem, data exploration and preparation, statistical hypothesis testing, feature engineering, modelling, model fine-tuning, storytelling with data, operationalization and model tracking.
Responsibilities / Accountabilities
• Accessing, profiling, and analyzing various relational databases, datalake (HDFS), unstructured data (files, images), NoSQL or graph databases
• Applying statistical analysis and visualization techniques to various data, such as hierarchical clustering, t-distributed Stochastic Neighbor Embedding (t-SNE), LLE, EM, Ward, and PCA
• Generating hypotheses about the underlying mechanics of the business process
• Testing hypotheses using various quantitative methods
• Networking with business subject matter experts, product owners and product managers to better understand the business mechanics that generated the data
• Analysis of the data through descriptive, exploratory, inferential, and causal techniques
• Preparation of the data through standardization, normalization, imputation, cleansing, outlier detection, and formatting
• Engineering features for continuous and discrete data utilizing domain knowledge and statistical techniques
• Applying various ML, DL, Reinforcement Learning (RL) and Advanced Analytics techniques to create supervised, semi-supervised, self-supervised, and unsupervised models
• Evaluation and testing of AI models through cross-validation, A/B testing, bias and fairness evaluation, and Explainability / interpretability
• Utilizing SOTA methods in ML and DL to achieve the superior model performance
• Implementing novel deep learning architectures and employing the Neural Architecture Search (NAS), and Meta Learning techniques
• Collaboration with the Data Product Manager, Data Analysts, other Data Scientists, MLOps Engineers, ML Engineers, and Data Engineers to evaluate, implement, and deploy to production enterprise-grade Machine Learning and Deep Learning models
