Accounts Payable Specialist - US

About the Role

KMC Solutions is hiring a Mid to Senior Accounts Payable Specialist to join as a dedicated, full-time member of the finance team at our client. This role owns corporate card administration and vendor billing, and reports directly to the client's US Accounts Payable Manager. The role is expected to work independently with minimal supervision, with a partial daily overlap with US business hours to support real-time collaboration with the US AP team. This is not an entry-level position: we're looking for someone with proven AP experience who can self-manage their workload and catch their own errors before work is submitted for review.

Key Responsibilities

• Corporate Card Administration: Manage the end-to-end corporate card program (Ramp), including transaction coding, receipt collection and matching, spend-policy compliance checks, timely reconciliation, and resolution of disputed or flagged charges.
• Vendor Billing: Process vendor invoices end-to-end — intake, GL coding, matching against POs or contracts where applicable, routing for approval, and payment scheduling — while maintaining accurate vendor records and responding to vendor inquiries.
• Ramp Platform Ownership: Act as the team's power user of Ramp for card and bill-pay workflows, including approval routing, categorization rules, and day-to-day platform administration.
• Traditional AP Processing: Handle AP work outside of automated tooling as needed, including manual invoice entry, check or wire runs, vendor tax documentation (W-9/1099 support), and vendor master maintenance.
• AP Automation Tools: Work confidently across other AP and spend-management tools as Sigma's stack evolves (e.g., Bill.com, Expensify, Concur, Tipalti, or similar), and help evaluate or improve AP workflows.
• Self-Review & Quality Control: Independently self-check completed work for coding accuracy, duplicate payments, and policy compliance before submission; this role is expected to produce clean, audit-ready work with minimal rework.
• US Team Collaboration: Coordinate daily with Sigma's US AP Manager and AP team during the shared overlap window to align on priorities, escalations, and deadlines.
• Month-End Support: Support AP-related month-end close activities, including accrual schedules, AP aging analysis, and open-item reconciliations.
• Process Improvement: Flag and recommend improvements to AP workflows, controls, and documentation as the team and tooling scale.

Qualifications & Experience

• Bachelor's degree in Accounting, Finance, or a related field.
• 4+ years of progressive, full-cycle Accounts Payable experience — this is a mid-to-senior role, not a junior or entry-level position.
• Hands-on experience with Ramp, or a comparable corporate card / spend-management platform, strongly preferred.
• Solid understanding of full-cycle AP: invoice processing, matching, and vendor management.
• Exposure to at least one other AP automation or spend tool (e.g., Bill.com, Expensify, Concur, Tipalti).
• Demonstrated attention to detail and a track record of self-reviewing work rather than relying on downstream catches.
• Excellent written and verbal English communication skills; comfortable working directly with a US-based finance team.
• Prior experience supporting a US-based, VC-backed, or multinational software company is a plus.
