Job description

Most AR/AP openings hand you one side of the work and a stack of invoices. This one is both sides, in a 40-person company where you will know the jobs behind the numbers you are processing.

Athena Engineering is a family-owned mechanical HVAC and building automation contractor. We hold our own prime contracts and self-perform the work with our own crews. We have been in business 41 years, we are based in San Dimas, and we work from Santa Barbara to San Diego on commercial, industrial, and institutional buildings. You would join an accounting department of three, reporting to the Accounting Manager.

You do not need a degree for this job. Plenty of employers ask for one on a role like this out of habit. We care what you have actually done in a construction accounting office. An Associate in accounting is helpful and it is not a requirement.

What you will do

You will process and input vendor and subcontractor invoices, code them to the right job and cost code, write purchase orders, and match invoices against those purchase orders and contracts. You will create customer invoices, keep accounts current, and make the calls and send the emails that bring past-due money in the door.

You will request lien waivers from subcontractors and suppliers, maintain the preliminary notice file, process customer credit applications, and set up new vendors with the documentation we need before anyone gets paid. Billing is a team function here, split across accounting, the Project Managers, and the Project Administrators by skill and seniority, and you will carry the portion assigned to you.

You will also be in Excel constantly, building spreadsheets that calculate on their own.

What you need

• One to two years of accounting experience covering both accounts payable and accounts receivable. Experience on only one side does not qualify.
• One year of commercial construction accounting.
• Hands-on experience in a true construction or mid-market ERP system, such as Sage ERP, Oracle, Trimble, or NetSuite. QuickBooks on its own is not equivalent for this role.
• Advanced Excel. You should be able to build a calculating spreadsheet from a blank sheet, write and troubleshoot formulas, and run basic macros.
• Real command of math, numbers, and logic. One transposed number means somebody gets paid or billed the wrong amount, and somebody else spends hours finding out why.
• A high school diploma or GED. No college degree is required for this position.

What helps

Experience with Sage Intacct and Procore, since both are used here every day. Experience working with subcontractors and material vendors. Familiarity with lien waivers, preliminary notices, and California lien deadlines.

Who fits here

The person who does well in this seat is organized, direct, and quick with numbers, and does not need somebody standing over them. The one who does not do well is the one who says "that's not my job." We cover a lot of territory with 40 people, and everyone here steps outside their own lane when the work calls for it.

Pay, schedule, and benefits

Pay: $25.00 – $30.00 per hour, non-exempt.

Schedule: Monday through Friday, 7:00 AM to 4:00 PM, on site at our San Dimas office. This is not a remote or hybrid position. Occasional overtime comes up during busy billing periods.

Benefits

• Medical coverage with PPO and HMO plan options
• Dental, employer-paid for the employee
• Vision, employer-paid for the employee and family
• HSA and FSA options
• 401(k) with company match
• Paid time off and paid holidays
• Life insurance and an Employee Assistance Program
• Wellness benefit through Holisticly
