Original job description

We are TRADER, a Canadian leader in digital automotive solutions. Our flagship brands - AutoTrader.ca, AutoSync, Dealertrack Canada and CMS - help Canadians buy, sell, and finance vehicles with confidence.

Learn more at tradercorporation.com.

As part of AutoScout24 group, Europe’s largest online car marketplace, we’re shaping the future of automotive retail in Canada and beyond.

As Senior Data Scientist, you will be key contributor within our global Data Science organization, shaping AI and machine learning systems that sit at the core of our marketplace platforms across Europe and Canada.

You design, build, and operate machine learning and GenAI systems that run in production and matter to the business. You work on complex, ambiguous problems, exercise strong technical judgment, and take responsibility for outcomes - not just models. While this is a hands-on role, you are also expected to influence technical direction, raise the bar for engineering practices, and enable other data scientists and engineers to succeed. This position is permanent and based in Toronto.

What you’ll do

Own ML and GenAI systems end-to-end in production, including problem framing, system design, deployment, monitoring, and continuous improvement

Make sound architectural and methodological decisions for ML systems on AWS, balancing robustness, observability, cost, and long-term maintainability

Partner closely with Product, Engineering, and Business leaders to turn ambiguous problems into ML-enabled product solutions with clear outcomes

Operate and evolve ML systems deployed across multiple countries and markets, accounting for differences in data distributions, regulations, and constraints

Mentor other data scientists through hands-on technical guidance, design reviews, and shared ownership of systems

What you’ll need

Advanced degree in Computer Science, Engineering, Mathematics, or a comparable field

6+ years of experience building and owning production ML systems end-to-end in a real-world environment

Strong hands-on expertise in Python and modern ML frameworks, with the ability to ship, operate, and evolve ML systems in production

Solid experience with AWS and MLOps practices, including deployment, monitoring, and operating ML systems at scale

Practical experience applying GenAI / LLMs in applied or production contexts, with a clear understanding of trade-offs and limitations

Ability to influence technical decisions through clear judgment and collaboration, not formal authority

Experience supporting and guiding more junior data scientists through hands-on collaboration, code reviews, and technical feedback

Strong sense of ownership and accountability for outcomes, with a pragmatic approach to trade-offs and delivery

What’s in it for you

We understand that there is life at work and life outside of work. Here are a few benefits that support us to be our creative best.

Gym discounts
Employee and Family Assistance program
Virtual wellness events
Conferences & training budget
Regular internal training programs
Financial planning with 3% matching Pension
Competitive salary
Annual bonus structure

The base salary range for this position is CAD $180k – $210k.
