Accounting/Office Assistant

Paradigm Mechanical Corp. • Santee, CA

9d • $28 - $33 • Onsite

About The Position

We're a mechanical contractor in East County San Diego, built from scratch over 15 years into an $18–24M commercial and federal construction business, with a refrigeration service company we acquired and are growing. Two brands, one team. Our purpose is simple: we solve complex challenges for our clients in ways others can't or won't. That takes people who care about getting it right. We're looking for an organized, detail-driven accounting assistant to run our accounts payable and purchasing. It's a real job with real ownership — you'll be the person who keeps money moving correctly between us, our vendors, and our subcontractors.

Requirements

• 2+ years of accounts payable or bookkeeping experience.
• Genuinely accurate data entry — this job rewards people who catch things.
• Comfort in Excel and an accounting system.
• Follow-through. A lot of this role is chasing paperwork until it shows up, without being reminded to.
• A friendly, professional way with vendors, subcontractors, and the field.

Nice To Haves

• Construction AP experience — lien releases, preliminary notices, subcontractor billings, retention.
• ComputerEase, Foundation, Sage 300 CRE, Viewpoint, or similar.
• Experience with W-9s and 1099 reporting.
• Purchase order and PO log experience.

Responsibilities

• Accounts payable for both brands — enter and code invoices in ComputerEase, prepare payment runs, and keep the AP files clean and current.
• Purchase orders — issue vendor POs, enter them in ComputerEase, and reconcile the PO log at month end.
• Vendor management — set up new vendors, maintain the vendor list, and keep W-9s, terms, and contact information current.
• Subcontractor administration — track subcontractor invoices, change orders, insurance certificates, preliminary notices, and lien releases, and follow up until they're in hand.
• Credit cards — reconcile, code, and pay company credit card accounts.
• Office support and data entry — assemble job books, manage the accounting inbox, and keep the office running.

Benefits

• $28 – $33 per hour depending on experience
• 401(k) Plan with Profit Sharing
• 100% Employer-Paid Health Insurance (choice of Sharp, Kaiser, or Scripps); optional dependent coverage via payroll deduction
• Voluntary Dental, Vision & Disability Coverage
• Generous Paid Time Off — vacation, sick leave, and paid holidays
• A small team where your work is visible and your name is known
