Senior Technical Support Engineer (T3)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Technical Support Engineer (T3) based in Canada.

This is a senior technical support role serving as the highest escalation point within a sophisticated support organization.
You’ll tackle complex, ambiguous customer issues that require deep investigation, debugging, and close collaboration with engineering teams.
The role sits at the intersection of software development, cloud infrastructure, SaaS integrations, and customer support.
You’ll diagnose root causes, reproduce difficult bugs, analyze logs and APIs, and use code to validate hypotheses and fixes.
You’ll also support critical enterprise customers, including complex onboarding, data restoration, and high-priority incident resolution.
Beyond resolving individual issues, you’ll identify recurring patterns and help improve products, documentation, and internal support capabilities.
This opportunity is well suited to a technically curious problem-solver who thrives in high-stakes environments, values ownership, and enjoys turning difficult customer problems into durable solutions.
