Sr. AR Specialist

About Engine

At Engine, we’re transforming business travel into something personalized, rewarding, and simple. For too long, managing travel and spend has been overwhelming and fragmented — we’re here to change that. We believe the future of travel should be seamless and powered by technology that delights customers at every step. That’s why we’re building a platform that brings together corporate travel, a powerful charge card, and modern spend management in one place.

To make this vision real, we’re looking for exceptional, mission-driven people to help redefine how businesses manage and experience travel.

More than 20,000 companies already rely on Engine to support over 1 million travelers and billions in annual bookings each year. Cash flow positive with rapid growth, we pair exclusive Engine-only rates, industry-leading rewards, and intelligent automation to help businesses save money while delivering world-class personalization and convenience.

Backed by Telescope Partners, Blackstone, and Permira, Engine has been recognized as one of the fastest-growing travel and fintech platforms in North America, with honors including the Deloitte Fast 500 and Built In’s Best Places to Work.

Your Mission

As part of the Engine team, you’ll play a vital role in an environment where innovation meets collaboration. Here’s what you’ll take charge of:

• 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.

What You’ll Bring to Engine

We’re looking for someone who’s ready to make an impact and grow alongside us:

• 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.

Applications for this role will be accepted through 8/14/26 or until the role is filled. We encourage you to apply early, as we may begin reviewing applications before the deadline.
