Job Description

The Accounts Payable Representative II plays a key role in supporting a high-volume, fast-paced, and operationally complex environment. This position is best suited for a highly capable, detail-oriented professional who thrives in ambiguity, adapts quickly to change, and can consistently deliver accurate results under pressure.

This role requires strong analytical thinking, sound judgment, and the ability to independently manage competing priorities. The successful candidate will demonstrate ownership, accountability, and a proactive approach to identifying issues, driving resolution, and contributing to process improvements.

Why This Role Stands Out

This is not a transactional AP role—this is an opportunity to operate as a trusted, high-impact contributor within a fast-moving organization. You will be expected to think critically, act decisively, and continuously improve how work gets done.

• Own the end-to-end processing of invoices, ensuring accuracy, completeness, and timeliness in a high-volume environment
• Critically review invoices and supporting documentation; identify discrepancies and independently drive issue resolution
• Execute accurate and efficient data entry within ERP systems while maintaining strong internal controls
• Review and validate employee and contractor expense reports, ensuring strict adherence to company policies; provide clear guidance and challenge where appropriate
• Act as a trusted partner to internal stakeholders and external vendors, resolving inquiries and driving accountability
• Maintain and update vendor master data with a strong focus on data integrity and compliance
• Support month-end close processes, including accruals and reconciliation activities
• Identify inefficiencies, recommend process enhancements, and contribute to continuous improvement initiatives
• Manage competing priorities effectively while consistently meeting daily, weekly, and monthly deadlines

• High School Diploma or GED (Bachelor’s degree preferred)
• 2+ years of Accounts Payable or relevant accounting experience in a fast-paced, high-volume environment
• Demonstrated ability to operate effectively in a rapidly changing and complex setting
• Strong critical thinking and problem-solving skills with the ability to navigate ambiguity
• High level of ownership, accountability, and attention to detail
• Excellent communication skills, with the ability to engage professionally across all levels of the organization
• Proven ability to prioritize, multi-task, and meet deadlines without sacrificing quality
• Advanced proficiency in Microsoft Excel (including data analysis and reconciliation)
• Experience working independently with minimal oversight while contributing to a collaborative team environment

Preferred Qualifications

• Bachelor’s degree in Accounting, Finance, or related field
• Experience with Oracle Financials or comparable ERP systems
• Experience with Concur or other expense management platforms
• Exposure to process improvement initiatives or automation efforts
