Full job description

Position Summary

The Assistant Controller supports day-to-day accounting operations and helps maintain accurate, complete, and timely financial records across multiple entities within our group of companies. Reporting to the Controller, this role supports general ledger integrity, contributes to month-end and year-end close, and helps ensure financial information is prepared in accordance with internal policies and applicable accounting standards.

The successful candidate will work alongside the Controller and an established finance team (which includes dedicated resources for accounts payable, payroll, accounts receivable, and cash flow management), progressively taking on broader responsibilities. This role will also serve as the Controller’s backup, stepping in to cover controllership responsibilities during absences and providing continuity of the finance function. As the group continues to grow, additional opportunities will become available for the right candidate to expand their scope and advance their career.

Working closely with the Controller and cross-functional teams, this position prepares journal entries, performs reconciliations, investigates variances, and supports audit-ready financial reporting. The Assistant Controller is expected to manage competing priorities, maintain strong documentation, and actively identify opportunities to modernize processes, strengthen controls, and increase the efficiency of the close cycle, including through the thoughtful adoption of AI and automation tools.

Key Responsibilities

Support month-end and year-end close across multiple entities, ensuring deadlines are met and deliverables are completed accurately and on time
Prepare, review, and post recurring, standard, and adjusting journal entries with supporting documentation
Maintain the close checklist, track outstanding items, and follow up with stakeholders to keep the close process on schedule
Maintain general ledger accuracy by reviewing account activity, verifying coding, and ensuring transactions are recorded correctly
Prepare bank reconciliations and investigate reconciling items to ensure cash balances are complete and accurate
Prepare and review balance sheet reconciliations, identify variances, and resolve discrepancies in a timely manner
Manage related-party and intercompany transactions, including reconciliations and resolution of out-of-balance items
Reconcile subledgers, including accounts receivable, accounts payable, and payroll, to the general ledger
Maintain organized supporting schedules and documentation for internal review and external audit requirements
Follow internal controls, accounting policies, and standard procedures to support accurate and compliant financial reporting
Assist with internal and external audit requests by preparing schedules, gathering documentation, and responding to information requests
Support revenue recognition, accruals, prepaid expenses, and other month-end accounting activities as needed
Cross-train with the Controller on cash flow management, financial reporting, and group-level consolidations, providing coverage and continuity as needed
Partner with operational and technical teams across the group to investigate and resolve issues that affect financial reporting (e.g., GL coding errors, billing or provisioning discrepancies, sales-to-GL reconciliation issues)
Champion the adoption of AI tools, automation, and modern accounting technology to streamline workflows, improve accuracy, and reduce manual effort across the finance function
Identify opportunities to improve accounting processes, strengthen documentation, and increase team efficiency
Provide ad hoc accounting and financial support to the Controller and finance team as needed

Qualifications

Education & Experience

Bachelor’s degree in accounting or finance, or equivalent related experience
CPA designation, or actively enrolled in the CPA Professional Education Program (PEP) with a clear path to designation, is required
3–5 years of progressive accounting experience, preferably in a multi-entity environment
Experience with month-end close and general ledger activities
Experience with related-party and intercompany transactions and reconciliations
Experience in a multi-currency environment
Experience supporting or leading process improvement, system implementation, or finance transformation initiatives is an asset
Exposure to telecommunications, ISP, subscription-based, or recurring-revenue businesses is an asset

Technical Skills

Strong knowledge of accounting principles; ASPE or IFRS experience preferred
Knowledge of revenue recognition principles, particularly in subscription or recurring-revenue environments
Proficiency in Microsoft Excel and accounting systems such as QBO and Spire
Intercompany accounting experience is an asset
Demonstrated curiosity about and practical experience using AI tools (e.g., Claude, ChatGPT, Copilot) to improve productivity, analyze data, draft documentation, or automate routine accounting tasks
Comfort working with modern finance tools and an openness to moving away from manual processes in favour of automated, integrated workflows

Core Competencies

Strong attention to detail and accuracy
Ability to manage multiple priorities and meet deadlines
Strong analytical and problem-solving skills
Strong organizational and documentation skills
Ability to work independently and collaborate across teams
Forward-thinking mindset, actively looking for better, faster, smarter ways to do the work rather than defaulting to “how it’s always been done”
Leadership potential and the ambition to grow into a Controller-level role over time
Strong communication skills, with the ability to work across technical and non-technical teams
