Join PJX’s growing team of passionate OOH experts! We are looking for a precise, proactive, and analytical teammate to join our finance and accounting operations. Project X Media is an award-winning, independent OOH media agency and a key subsidiary of Talon, a UK-based global Out of Home business. We partner with a diverse range of clients, from independent agencies of all types to leading and challenger-level brands.

The Senior Accounts Payable Specialist plays a critical role in our media agency finance function, overseeing the accuracy and efficiency of both media owner payments/reconciliations and company overheads. In addition to managing complex AP workflows, this role will directly oversee and review the work of our offshore AP support team, serving as the primary quality control point for invoice coding and payment file preparation.

Audit and validate payment files prepared by the offshore team for accuracy, cash flow alignment, and strict payment approval compliance before submission, while continuously identifying opportunities to refine and optimize the payment workflow.

• Supplier Onboarding & Compliance: Ensure strict compliance across all supplier onboarding procedures, vendor master data maintenance, payment term validations, and internal payment approval controls.

• Offshore Team Oversight & Quality Control: Oversee day-to-day outputs of our offshore AP team who handle high-volume invoice coding, data entry, and initial payment file preparation; review work for accuracy, provide ongoing guidance, and maintain clear standard operating procedures.

• Media Accounts Payable & Reconciliations: Perform high-level matching, auditing, and reconciliations of media owner/vendor invoices against campaign buy data and internal financial systems; manage complex discrepancies and high-priority accounts.

• Overheads Accounts Payable: Oversee end-to-end processing for company overhead vendor invoices (e.g., IT, subscriptions, consultants, and general operational costs), ensuring proper contract matching and approval workflows.

• Vendor Relations: Serve as the main escalation point for vendor statement reconciliations, billing disputes, and payment status inquiries.

• Mailbox & Workflow Management: Manage the AP queue and mailbox, ensuring queries are triaged effectively between the internal team and offshore partners.

• Month-End Close Support: Support the month-end close by ensuring accurate and timely AP sub-ledger close, reconciliations, and accruals.

• Process Improvement: Identify and implement improvements to AP processes, increasing efficiency and scalability

• Cross-Functional Collaboration: Partner cross-functionally across operations, media, client development, and finance to streamline billing workflows, improve data integrity, and maintain strong internal controls.

We’re looking for a precise, smart, and team-oriented person with:

Core Qualifications:

• Experience: 3-5+ years of progressive, hands-on Accounts Payable experience handling high-volume supplier and vendor invoices, supplier onboarding, and payment runs.

• Delegation: Proven experience auditing payment files, reviewing work, and coordinating workflows with offshore, third-party, or junior team members.

• Industry Background: Media industry or advertising agency experience is strongly preferred (OOH experience is a major plus); experience in a high-volume, multi-vendor transactional environment required.

• Technical & System Skills: Advanced proficiency in MS Excel (vlookups, pivot tables). Experience with ERP systems such as Sage Intacct or NetSuite preferred.

Mindset & Key Attributes:
