About the role

Lone Tree Inc. is a Lethbridge-based family enterprise with a small, close-knit team that handles a wide range of work under one roof: accounting, HR, IT, marketing and real estate administration. We're looking for an experienced Senior Corporate Administrator to work directly with our CEO and keep the business running smoothly.

This is a senior role. You'll own the books, lead how our office systems and processes work, and support the CEO on strategic planning. If you've run an office before and want a job where your judgment is trusted and your work is visible, this is it.

What you'll do Accounting and financial administration

• Oversee full-cycle accounts receivable and payable, including invoicing, collections, vendor payments and reconciliations.
• Lead month-end and year-end processes and prepare financial reports for the CEO.
• Review the accuracy of transactions processed by team.

Strategy and CEO support

• Support the CEO in completing the annual strategic plan and each division's annual objectives, including KPI tracking (Scaling Up methodology).
• Build and maintain the corporate calendar for the Board, CEO, corporate functions and divisions.
• Prepare materials for the Board and investors, and keep the investor portal up to date.

Systems, technology and process improvement

• Lead improvement projects: standardize tools, automate recurring reports and simplify administrative processes.
• Manage the SharePoint site and company websites, and coordinate IT support with outside providers.
• Write and maintain process and procedure manuals for each functional area.

HR administration

• Keep HR policies and records current.
• Run the quarterly performance review and STIP processes on schedule, and help managers handle HR tasks on their own.

Leadership

• Build strong working relationships with management, staff, vendors, investors and community partners.

Requirements What you bring

• At least 5 years of senior administrative, office management or executive support experience.
• Full-cycle bookkeeping or AR/AP experience, including month-end. A diploma or coursework in accounting or business administration is an asset.
• Strong skills in Microsoft 365 (Excel, Word, Outlook, Teams, SharePoint) and accounting software. Experience with Dext, Adobe or website platforms is a bonus.
• A track record of improving processes, not just following them.
• Experience supervising or guiding other staff.
• Sound judgment and discretion with confidential financial, personnel and investor information.
• Clear communication with everyone from the CEO and Board to outside vendors.

Why Lone Tree

• Growth. Assist the company with long term growth, allowing you to grow with the company.
• Direct access to the CEO. Your input shapes real decisions.
• Flexibility. 30 to 40 hours a week, with flexibility for the right person.
• Variety. Accounting, strategy, systems and people work, all in one role.
• A small team where everyone's contribution matters.
