Software Engineer – Machine Learning Intern/Co-op

About Bree

Bree is a consumer finance platform that brings better, faster, and cheaper financial services to over half the Canadian population who live paycheck to paycheck. We operate in a huge, but overlooked market in a country with the least amount of financial technology innovation in the developed world. Our first act is to become the cheapest and best provider of short-term credit to the 20 million people in Canada who live paycheck to paycheck.

500,000+ Canadians have already signed up with Bree and we believe we are just scratching the surface. We are at an exciting intersection of product market fit, explosive growth, and a clear path to becoming one of the most important FinTechs in Canada.

We are at 8-figures of annualized revenue, growing rapidly, profitable, and have had zero voluntary employee churn. We were part of Y Combinator's Summer 2021 batch and raised a $2M seed round shortly after.

About the Role

We’re looking for a Software Engineer, Machine Learning Co-op to build and scale high-impact, world-class ML systems. You’re passionate about deploying AI solutions, optimizing performance, and driving measurable results. Your work will power critical decisions and shape the future of our technology.

We are open to 4, 8 and 12 month co-op terms.

What You'll Do

• Design, develop, and deploy end-to-end machine learning pipelines, ensuring efficiency in training, validation, and inference.

• Implement MLOps best practices, including CI/CD for ML models, model versioning, monitoring, and retraining strategies.

• Optimize ML models using feature engineering, hyperparameter tuning, and scalable inference techniques.

• Work with structured and unstructured data, leveraging Pandas, NumPy, and SQL for efficient data manipulation.

• Apply machine learning design patterns to build modular, reusable, and production-ready models.

• Collaborate with data engineers to develop high-performance data pipelines for training and inference.

• Deploy and manage models on cloud platforms (AWS, GCP, Azure) with containerization and orchestration tools like Docker and Kubernetes.

• Maintain model performance by implementing continuous monitoring, bias detection, and explainability techniques.

What You'll Need

• Proficiency in Python and familiarity with ML libraries like Scikit-learn, LightGBM, and PyTorch.

• Strong understanding of machine learning algorithms, including supervised and unsupervised learning techniques.
