Assistant Controller at McKinley Children's Center – San Dimas, California

Assistant Controller

San Dimas, CA | Full-Time | Exempt

Numbers matter. So does impact.

At McKinley, finance isn’t just about closing the books; it’s about ensuring children and families receive the services they depend on.

We are a multi-service nonprofit organization with an annual operating budget of nearly $50 million, funded through a diverse mix of federal, state, county, and private sources. Our financial environment is sophisticated, regulated, and mission-driven — and we’re looking for an Assistant Controller who thrives in that complexity.

If you are a sharp, detail-oriented accounting professional ready to step into a broader leadership role — while still staying hands-on — this could be your next move.

The Opportunity

Reporting directly to the Controller, the Assistant Controller plays a critical role in safeguarding the organization's financial integrity. This is not a purely supervisory position — it’s a leadership role for someone who enjoys rolling up their sleeves to help shape processes, structures, and financial clarity.

You’ll help oversee the accounting operations of a $50M nonprofit, lead the close process, support audits, strengthen internal controls, and ensure compliance with complex government funding requirements.

You will also serve as the Controller’s right hand — stepping in when needed and helping elevate the finance function.

Compensation and Benefits:

The pay range we’re offering is $100,000 - $110,000 annually.

What You’ll Be Responsible For

• Leading monthly and year-end close processes

• Preparing and reviewing journal entries, reconciliations, and financial statements

• Overseeing grant accounting, restricted funds, and contract billing

• Supporting annual audits and serving as a key liaison to external auditors

• Ensuring compliance with GAAP and OMB Uniform Guidance

• Strengthening internal controls and improving accounting processes

• Supervising and mentoring accounting staff

• Supporting budgeting, forecasting, and financial analysis

• Preparing reports for executive leadership and the Board

This role requires someone who understands both the technical precision of accounting and the operational reality of a growing nonprofit organization.

Who You Are

You might be:

• A Senior Accountant ready for your first Assistant Controller role

• An Accounting Manager looking for broader exposure and leadership

• A CPA who wants meaningful work in a mission-driven organization

• A nonprofit accounting professional who enjoys complexity and problem-solving

You are:

• Technically strong in GAAP and nonprofit fund accounting

• Comfortable working with large datasets and advanced Excel

• Experienced in managing full-cycle accounting

• Confident in audit environments

• Detail-oriented but able to see the bigger financial picture

• Comfortable holding high standards for yourself and others

Qualifications

• Bachelor’s degree in Accounting, Finance, or related field (required)

• CPA strongly preferred

• 5+ years of progressive accounting experience

• Supervisory experience preferred

• Nonprofit accounting experience required

• Experience with $20M+ organizations strongly preferred

• Experience with SAGE 100 or similar ERP systems preferred

Why This Role Stands Out

This is a real growth opportunity.

You will gain exposure to executive leadership, Board reporting, government compliance, and complex funding structures, all while making a direct impact in the community.

You won’t be siloed.
You won’t be just reviewing spreadsheets.
You will be helping shape financial operations that support children and families every day.

If you’re ready for a role that challenges you technically, grows you professionally, and aligns with meaningful work, we would love to meet you.
