Tax Director

We are seeking a Tax Director who will own the company’s global tax function end to end. This is a high-visibility, high-autonomy role that reports directly to the VP Finance & Controller and operates at the organizational level: setting strategy, establishing cross-functional standards, and addressing complex challenges that shape how the company is structured and how it scales toward a potential liquidity event.

Our C-level team is based in Boston, while the global finance function is split between Montreal and Athens. This role is based in Montreal, alongside the VP Finance & Controller. This is a senior individual contributor role with no direct reports.

• Maintains awareness of permanent establishment risk, withholding tax obligations, and treaty positions across the company’s operating footprint.
• Designs and implements a transfer pricing framework appropriate for a multi-entity, multi-jurisdiction SaaS business, including intercompany service agreements and IP licensing arrangements.
• Prepares or oversees preparation of transfer pricing documentation in line with OECD guidelines and local requirements.
• Partners with Finance, Legal, and Operations to ensure intercompany cost allocations reflect arm’s-length pricing and are consistently documented.
• Manages transfer pricing exposure in connection with any intercompany financing, restructuring, or entity-level changes.

Tax Planning & Structuring

• Orchestrates and optimizes the external tax advisor network across jurisdictions, driving better strategic advice at lower total cost.
• Identifies and evaluates tax planning opportunities, including SR&ED and US R&D tax credits, as well as equivalent incentives in applicable international jurisdictions.
• Advises on the tax implications of business decisions, including new market entry, entity restructuring, contract structures, legal entity structure, and revenue recognition approaches for SaaS and project-based engagements.
• Supports the CFO and Controller on tax-efficient structuring as the company positions for growth, M&A activity, or a potential exit.
• Assesses the tax treatment of software and services revenue across jurisdictions, including permanent establishment and nexus considerations.

Audit Defense & Controversy

• Manages all income tax audits and examinations, coordinating with external counsel and advisors as needed.
• Maintains documentation and technical positions sufficient to defend returns and uncertain tax positions.
• Tracks and resolves notices from tax authorities across all jurisdictions in a timely and organized manner.

Indirect Tax — Oversight

• Maintains oversight of the company’s indirect tax compliance program (US sales tax, Canadian GST/HST/QST, VAT/GST across international jurisdictions), with execution managed within the controllership function.
• Provides technical guidance on indirect tax matters arising from new products, jurisdictions, or contract structures.
• Ensures the company’s indirect tax obligations are appropriately reflected in billing systems, customer contracts, and financial reporting.

• Deep technical command of ASC 740 and the US federal income tax regime.
• Hands‑on experience with multi‑jurisdiction transfer pricing, including documentation and intercompany agreement design.
• Track record with R&D tax credits and the tax characterization of SaaS and software revenue.
• Strong written and verbal communication skills, with the ability to translate technical tax matters for a diverse audience.
• Track record coordinating work across Finance, Legal, Operations, and external advisors — building trusted networks and driving alignment without direct authority.

Nice to have

• Working knowledge of Canadian corporate tax, including hands‑on experience with SR&ED claims.
• Experience advising on or executing M&A diligence, post‑acquisition integration, or entity restructuring from a tax perspective.
