Harbinger: Familiar Form, Revolutionary Foundation.

We are seeking an experienced, self-directed Accounts Payable Accountant to own the full procure-to-pay (P2P) cycle across multiple legal entities and business units. The right candidate brings solid GAAP knowledge, familiarity with SOX internal controls, and the professional maturity to work accurately and independently in a dynamic, multi-entity environment. This is not a role for someone who needs everything figured out before they can be effective.

You will be expected to execute at a high level, stay organized under competing demands, identify and clearly communicate issues to management, and adapt as processes and systems evolve around you. WHAT YOU’LL WALK INTO We believe in being upfront about the environment you’re joining: The Current Environment A multi-entity, multi-business-unit structure requiring careful entity-level coding and cost allocation AP processes that are being actively assessed and improved by management Data quality issues that are being identified and remediated — your accuracy and attention to detail matters here Systems that may be mid-configuration or in transition A team rebuilding its foundation — reliability, consistency, and clear communication will be valued above all If you’re the kind of person who looks at that list and thinks “I can work in this,” we want to talk.
