Collabera is seeking two Senior Python Developers to support a Ticketing Automation Project within the Public Markets Technology team with an investment Industry in Downtown Toronto. This role is focused on modernizing and automating legacy ticketing workflows, transitioning from a manual, inefficient process (legacy Dash system) to a scalable, automated solution.

• 8–10+ years of experience as a Python Engineer
• Strong hands-on Python development experience
