International Retirement Actuarial Consultant

We are seeking an actuarially trained consultant to join our Montreal-based team supporting multinational clients with international pension plan administration and the coordination of international pension accounting and disclosure deliverables.

International experience is an advantage but not required.

This is a hybrid role with a requirement to work at least three days per week in the office

Key responsibilities

International pension plan administration

• Serve as a primary point of contact for plan participants (often executives) and client stakeholders; triage, track, and manage requests via mailbox and phone line.
• Perform and/or review pension benefit calculations and prepare participant statements and other communications.
• Maintain accurate member records, trackers, and databases throughout the employment lifecycle.
• Lead recurring administration activities (as applicable), such as periodic website/modeler updates, monthly payments processing, and bank reconciliations.
• Identify opportunities to improve processes and administrative procedures while maintaining strong controls and documentation.

International pension accounting and disclosures (coordination and analytical support)

• Coordinate the consolidation of worldwide pension and other post-employment benefit information for financial reporting.
• Prepare IAS19 results, including non-routine events, based on inputs from local valuation actuaries.
• Liaise with local actuaries/consultants globally to obtain assumptions, disclosures, and supporting detail; coordinate timelines, deliverables, and follow-ups.
• Review inputs received from local actuaries for reasonableness, consistency, and compliance with applicable accounting standards (e.g., IFRS and other relevant frameworks), escalating issues as needed.
• Support production of client-ready materials for senior consultant review (including technical summaries, disclosure coordination trackers, and deliverable status reporting).

Consulting, project management, and advisory support

• Contribute to global benefits inventories, multi-country audits/benchmarking, and benefits reviews for multinational clients.
• Support senior consultants with retirement plan design considerations, funding strategy support, and competitive benefit analysis, as needed.
• Demonstrate strong project management discipline: plan work, manage priorities, and deliver high-quality outputs on time in a time-recording consulting environment.
• Work effectively within integrated teams across offices and disciplines; participate in peer reviews and knowledge sharing.

What you need to have: 

• 2–8 years of relevant experience in pension administration, retirement consulting, actuarial/benefits consulting, or related roles.
• Bachelor’s degree in actuarial science, mathematics, statistics, finance, business/commerce, administration, or a related field.
• Actuarial competency with strong analytical skills (e.g., comfort working with plan data, calculations, assumptions, and reconciliations). Progress toward actuarial credentials is an asset.
• Fluency in both English and French.
• Advanced Excel skills and strong proficiency in Microsoft Office (Excel, PowerPoint, Word).
• Strong attention to detail, sound judgment, and ability to be technically accurate in complex and/or uncertain environments.
• Strong communication skills (written and verbal) and ability to translate technical topics into clear client-ready messages.
• High sense of accountability with the ability to independently manage multiple tasks and competing deadlines.

What makes you stand out:

• Exposure to international benefits, multinational clients, or working with global stakeholders.
• Experience coordinating or supporting pension/post-employment benefit accounting disclosures.

Why join our team:
