Senior AR Specialist

Job Description: • Execute across both customer and supplier AR workstreams—including invoicing accuracy, cash application, supplier reconciliations, and collections follow-up—operating as an owner across both sides of the portfolio. • Monitor customer and supplier invoice data for anomalies, errors, and billing discrepancies—proactively, not reactively. • Own resolution outcomes, not just escalation. When an issue surfaces—drive it across teams (Engineering, Client Ops, BPO) until it is closed cleanly, with documentation on root cause and resolution. • Serve as AR’s operational voice in Product and Engineering conversations: surface data integrity issues, validate billing logic changes, and flag when new product flows create AR risk before launch. • Support month-end close activities including AR reconciliations, aging review, and bad debt input preparation for the Sr Manager. • QA the BPO agent workflow: review output quality, identify recurring errors, and escalate training gaps or process failures rather than working around them. • Support automation initiatives by mapping manual steps, identifying handoff points, and validating outputs post-implementation. Requirements: • 3–6 years of AR, billing operations, or accounting experience in a high-volume, transaction-heavy environment. • Hands-on experience with billing disputes, reconciliations, cash application, and collections execution across both portfolios. • Demonstrated ability to identify root causes, not just process symptoms—and a track record of driving issues to resolution rather than handing off and waiting. • Experience working alongside Engineering or Product on billing data, payment flows, or system fixes. • Strong analytical skills: comfortable working in spreadsheets and data tools to investigate discrepancies, track issue patterns, and support aging and reconciliation analysis. • Familiarity with BPO-managed workflows and the ability to QA agent output, flag errors constructively, and identify training or process gaps upstream. • NetSuite & Salesforce experience preferred. Comfort interfacing directly with customers and suppliers on complex billing or invoice matters. Benefits: • Compensation: Competitive base pay tied to role and experience, with opportunities for bonuses, commissions, and equity. • Benefits: Check out our full list atengine.com/culture. • Environments for Success: Different roles have different needs in terms of the environments that drive success which is why we have a hybrid-hub model.
