As our Senior Tax Analyst, you will play an important role in supporting the tax function of a rapidly scaling Canadian technology leader. Reporting directly to the Senior Tax Manager, you will gain hands-on visibility across corporate income tax, indirect tax, and ASC 740 provisions, working shoulder-to-shoulder with finance partners, external advisors, and cross-functional teams.

If you have a solid foundation in Canadian corporate tax and want to expand your toolkit into US state/federal, global compliance, and modern tax automation, this role could be right for you.

StackAdapt is a Remote First company; we are open to candidates located anywhere in Canada for this position.

• Innovation & AI: Experiment with AI tools and automation to eliminate manual routine tasks, rethink legacy processes, and streamline reporting.

• Tax Accounting & Reporting: Co-lead quarterly and annual income tax provisions under ASC 740, including building/updating provision models, calculating return-to-provision true-ups, preparing audit-ready financial statement disclosures, and liaising with external auditors.
