Accounting Manager

Anaheim, CA - Fully Onsite) | Travel to Lake Elsinore HQ Every Other Week

A rapidly growing Southern California company in the manufacturing/distribution space is seeking a hands-on, highly driven Accounting Manager to build and lead its accounting function from the ground up. This is a unique opportunity for someone who thrives in fast-moving environments, enjoys creating structure where none exists, and wants to have a real seat at the table as the business scales.

This is not a plug-into-an-existing-team type of role. There is currently no formal internal accounting department, and this person will play a critical role in transitioning accounting operations from an outsourced model to a fully internalized function over time. The ideal candidate is resourceful, detail-oriented, adaptable, and comfortable operating independently in an entrepreneurial environment.

What You’ll Be Doing:

  • Build and establish the accounting department from scratch, including processes, workflows, controls, and reporting structure
  • Partner closely with the outsourced accounting firm during the transition period, with the long-term goal of bringing accounting fully in-house
  • Own day-to-day accounting operations, bookkeeping, month-end close, reconciliations, payroll coordination, and financial reporting
  • Develop scalable accounting infrastructure to support rapid company growth
  • Work cross-functionally with leadership and operational teams to improve visibility, organization, and financial processes
  • Manage inventory and cost accounting functions related to manufacturing/distribution operations
  • Help create a more organized, process-driven financial environment while maintaining flexibility in a fast-paced culture
  • Travel to the Lake Elsinore headquarters approximately every other week for visibility and collaboration

What They’re Looking For:

  • Bachelor’s degree in Accounting, Finance, or related field required
  • 5+ years of accounting leadership experience in manufacturing, retail, or distribution environments
  • Experience building or rebuilding accounting processes and infrastructure
  • Strong understanding of inventory accounting and operational accounting workflows
  • Ability to work independently with minimal oversight
  • Someone who is proactive, adaptable, and comfortable in an evolving environment
  • Creative problem solver who can “figure it out” and keep things moving
  • Experience with QuickBooks, Xero, or similar ERP/accounting systems preferred

Culture & Environment:

This company is entrepreneurial, collaborative, and growth-focused. Leadership is looking for someone who can roll with change, help create structure, and become a trusted business partner as the company continues to scale.

The right person will enjoy building, creating, improving, and having direct impact on the future of the organization — not simply maintaining an already polished accounting department.

Benefits & Perks:

  • Medical coverage available, including PPO/HMO plan options
  • Company currently covers 100% of employee healthcare premiums, including family coverage
  • Opportunity to build and lead an accounting function from the ground up
  • High visibility role with direct partnership alongside ownership and leadership
  • Long-term career growth as the company continues scaling rapidly
  • Ability to make a real impact on operational and financial strategy
  • Entrepreneurial environment where ideas, process improvements, and initiative are valued
  • Strong sense of ownership and autonomy — not a micromanaged environment
  • Collaborative, team-oriented culture focused on growth and adaptability
  • Stable and growing company within the manufacturing/distribution industry

We look forward to your application!
