Accounting Integration Manager

Are you a corporate accounting manager, assistant controller, accounting systems manager, finance transformation manager, or post-acquisition integration leader who wants broader impact than a traditional close-focused role, but does not want to leave accounting behind? Colliers Engineering & Design is seeking an Accounting Manager, Integration & Accounting Transformation to join or growing team.

The Accounting Manager, Integration & Accounting Transformation combines strong technical accounting judgment with project leadership and business systems fluency. The role partners with acquired-company leaders and colleagues across Corporate Accounting, Finance, Operations, Information Technology, Human Resources, Treasury, Tax, and other functions to align accounting policies, processes, systems, controls, and reporting requirements. The successful candidate will translate complex accounting and operational needs into practical plans, lead data and process transitions, and remain engaged in core accounting and continuous-improvement work beyond individual integrations.

This is a multifaceted accounting role for someone who values variety and thrives on bringing clarity and structure to newly acquired businesses—and leaving their fingerprints on the results. It is designed for an accomplished accountant who enjoys solving complex problems, improving systems and processes, and helping newly acquired teams succeed. You will lead accounting and finance integration work from diligence through stabilization while also contributing to corporate accounting, close and reporting improvement, internal controls, and broader finance transformation initiatives.

The mix of work will evolve with the acquisition pipeline, giving you both ownership of the accounting and finance aspect of integrations and meaningful opportunities to strengthen the ongoing accounting organization.

This position offers a hybrid work arrangement; however, candidates must be able to work a minimum of three days per week in our Denver, CO office to support collaboration and business needs.

• Oversee chart-of-accounts mapping, historical data conversion, opening balance sheet preparation, account reconciliations, and validation of migrated financial information.
• Apply sound U.S. GAAP and close-process knowledge to resolve accounting issues, strengthen reconciliations, and support accurate and timely financial reporting.
• Partner with Corporate Accounting on selected close, reporting, policy, control, and process-improvement initiatives, particularly between active integration phases.
• Help integrate acquired entities into ERP, expense, banking, billing, reporting, and related financial systems; translate accounting requirements for technical and implementation teams.
• Coordinate cutover readiness, including master data, user access, vendor and customer setup, banking and remittance changes, reporting, training, and support plans.
• Build trusted relationships with acquired-company teams, facilitate cross-functional decisions, and communicate clearly through periods of change.
• Develop and continuously improve scalable playbooks, templates, checklists, standard operating procedures, controls, and handoff practices.
• Coach accounting team members and acquired-company personnel, share knowledge, and support adoption of new processes and systems.

• Bachelor’s degree in Accounting, Finance, Business Administration, or a related field.
