Geo-Technology Associates, Inc. (GTA) is seeking a talented Payroll & HRIS Specialist to join our team in Abingdon, Maryland. 

Own payroll. Improve processes. Help modernize our systems.

We’re a growing, project-driven AEC firm looking for a high-caliber Payroll Specialist who wants to do more than just push buttons. If you love accuracy, thrive in a fast-paced environment, and get excited about making processes better, this role gives you the chance to own payroll from end to end and play a key role in how we scale.

You’ll collaborate every day with HR, Accounting, Finance, and IT, support compliance across multiple states, and be hands-on as we evaluate and select our next HRIS/payroll system. This is the ideal role for someone who enjoys both the precision of payroll and the creativity of improving how it all works.

If you’re detail-obsessed, improvement-minded, and want your work to matter, you’ll love it here.

What You’ll Do

• Run accurate, timely payroll for all employees

• Maintain employee payroll data (new hires, terms, benefits, pay changes)

• Reconcile payroll accounts and proactively resolve discrepancies

• Support audits, reporting, tax filings, and multi-state compliance

• Partner with HR, Accounting, and IT to streamline and modernize workflows

• Contribute to the RFP, evaluation, and selection of our future HRIS/payroll platform

• Cross-train across HR, Finance, and Accounting — grow your skillset beyond payroll

• Bring new ideas, help us automate, and champion continuous improvement
