Senior Tax Manager

About The Role

We're seeking a Senior Tax Manager to own the Canadian tax function. Please note this is a hands-on Individual Contributor (IC) role; you will own and execute the work—including preparing work papers and reconciliations—without direct reports. You bring deep Canadian tax expertise, cross-border experience, and a forward-looking mindset around AI-driven practice improvement. As a real part of our lean global tax team, you will apply sound technical judgment to make the function faster and better than you found it.

• Own Canadian corporate income tax compliance — oversee the full compliance process across all required schedules and applicable provincial jurisdictions, and ensure quality and accuracy at every stage
• Own GST/HST and applicable provincial indirect tax compliance
• Maintain transfer pricing documentation and intercompany agreements — ensuring positions are technically sound, contemporaneous, and defensible under tax authority scrutiny; advise Finance and Legal on cross-border arrangements before decisions are made, not after
• Own the Canadian component of tax reporting, coordinating with the US team
• Stay ahead of Canadian tax change — federal, provincial, Pillar Two — and translate what matters into decisions Finance can act on before the deadline, not after
• Own the tax authority relationship: respond to correspondence and see inquiries through to resolution

• Flex into US income tax provision, federal and state compliance review, and month-end close as a meaningful contributor — not just backup capacity, but a senior person who can carry real workload when it counts
• Contribute to public company tax reporting on a shared basis with the broader team

• Reach for AI first — use Claude, Claude Code, and similar tools to accelerate research, draft technical memos, analyze notices, run calculations, and design repeatable workflows.
• Default to AI, don’t defer to it. The tools give you leverage; the work is still yours. Every output you put your name on — whether it’s a written position, a calculation, or a workflow result — is something you can explain and stand behind
• Tax work is multi-layered — some steps demand deep judgment, others not as much.
• Map the difference. Automate what's mechanical, build structured workflows for what's in between, and protect your focus for the analysis and positions that actually require you

• 10+ years of Canadian tax expertise, with a track record of being a senior Canadian tax voice in the room — the person others deferred to on technical questions
• Background at a major accounting firm in a Canadian corporate or international tax group
• Multinational tax experience — you’ve worked across US and Canadian tax obligations and understand how cross-border arrangements function in practice, not just in documentation
• Transfer pricing expertise beyond documentation review — you understand what makes a position defensible and you’ve had to defend one
• The ability to translate complex technical positions into clear, actionable guidance — you know the technically correct answer and you know which version of it the business should actually implement
• Meaningful US tax experience — sufficient to flex into provision, compliance, or month-end close and carry real workload during crunch periods
• CPA (Canada) or equivalent
• A track record of making the tax function faster and lighter than you found it — not just maintaining what exists, but leaving it better
• You've rebuilt something because of AI and it runs faster now. When something new lands, you don't prompt and paste — you interrogate it, pressure-test it, and know exactly where it's wrong before anyone else does

• Public company experience
• Experience at a technology company or business with material cross-border activity
• Familiarity with Net Suite, Snowflake, or similar finance and accounting platforms
