Part-Time Staff Accountant (Construction & Project Accounting)

About RES

Renewable Energy Services (RES) is a locally owned and operated solar system installer, with 30 years of experience providing innovative power solutions. We are passionate about the benefits of solar power and committed to its safe, reliable, and artful use on Hawaii Island today, and securing a sustainable future for generations to come.

Over three decades of service, RES has evolved beyond a traditional solar installer. Today our work includes residential and commercial construction projects, ongoing system maintenance and service, warranty support, inventory management, and long-term customer relationships. Our accounting environment reflects this complexity, combining elements of construction accounting, project accounting, inventory accounting, and service operations within a small business setting.

We are looking for someone who is comfortable working in an environment where operational decisions, project progress, and accounting are closely connected.

Position Summary

The Part-Time Staff Accountant (Construction & Project Accounting) is responsible for maintaining day-to-day accounting operations and supporting accurate financial reporting in a complex accrual-basis environment.
