Senior Data Scientist

Helcim Inc•Calgary, AB

8d•Hybrid

About The Position

We are looking for a puzzle-solving data detective who sees the freedom to build and experiment in high-impact areas for the awesome opportunity and responsibility it is. Join Helcim in the sweet spot of our growth. We have matured into a high-growth scale-up, retaining the agility and ambition of a startup while providing the stability, infrastructure, and resources of an established company. As a Senior Data Scientist, you will step into an environment primed for advanced data solutions. You won’t just be inheriting legacy systems. Instead, you will take ownership of developing data products, design autonomous agents, lead by example and mentor colleagues, and set the standard for how data science is done, all in the name of elevating our analytics and operations across the organization. On this team, you own the full lifecycle of our ML models and data products: from initial ideation and complex modeling to collaborating with our Data Platform team on deployment and monitoring. What we ship doesn't sit on a shelf. We solve complex problems around payments, fraud, credit, and marketing to deliver impact on two fronts: Supporting Independent Businesses: Every model you push out helps thousands of businesses across Canada and the USA thrive, directly supporting local economies and the people who run them. Improving Internal Operations: You will build models and systems that reduce manual bottlenecks. Your work directly improves the effectiveness and lives of the people in the office with you, helping us scale our operations smoothly. We operate with mature development processes, deploying in rapid 2-4 week cycles. We work hard to balance this speed with quality, remaining deeply accountable because we know how many people rely on the systems we build.
