Onyx Accounting Group

Scottsdale, AZ (Hybrid or Remote)

Onyx Accounting Group is a boutique accounting and advisory firm supporting closely held businesses with bookkeeping, controller, and CFO-level services. We work with clients who value accuracy, organization, and proactive financial partnership.

We’re seeking an experienced Controller to take full ownership of day-to-day financial oversight for a portfolio of clients and serve as a senior-level resource within our accounting team. This role is intended for candidates who are already operating at a controller level and are comfortable independently overseeing work, making judgment calls, and interfacing directly with clients.

What You’ll Do

• Own the month-end close process for multiple clients, from review through final delivery

• Oversee and review reconciliations, journal entries, and financial statements

• Ensure accuracy and consistency across client financials and reporting

• Prepare and review balance sheet and P&L analyses with supporting explanations

• Identify discrepancies, investigate variances, and determine appropriate corrections

• Serve as the primary controller-level point of contact for assigned clients

• Review work prepared by staff accountants and provide clear direction and feedback

• Collaborate with CFO and leadership on workflow improvement and process documentation

• Maintain organized, audit-ready client workpapers and support documentation

What We’re Looking For

• 7 years of progressive accounting experience with meaningful controller-level responsibility

• Demonstrated experience owning month-end close, not just assisting with it

• Strong working knowledge of GAAP

• Significant experience reviewing and approving work prepared by others

• Advanced proficiency in QuickBooks Online

• Strong Excel skills and comfort working independently with detailed financial data

• Ability to manage multiple clients and deadlines with minimal oversight

• Clear, professional communication skills with clients and internal team members

Nice to Have

• Experience in public accounting or outsourced accounting environments

• Prior client-facing advisory or controller-for-hire experience

• Familiarity with multi-entity structures

• Interest in process improvement and documentation

Why Onyx

• Flexible work environment

• Collaborative, experienced team

• Opportunity to work closely with CFO-level leadership

• Clear expectations and organized workflows

• Meaningful client impact

Compensation: Commensurate with experience
