About The Position

We’re hiring an AR & AP Associate to support our portfolio of clients by owning day-to-day accounts receivable and accounts payable processing. This role is critical to keeping our clients’ financial operations running smoothly and predictably.

The right person enjoys context, takes pride in clean execution, and knows when to escalate versus when to solve independently. Success in this role means AP and AR are accurate, timely, and predictable across the portfolio; clients view you as a trusted, reliable point of contact; risks and issues are surfaced early; and processes continuously improve, allowing engagement leads to spend less time firefighting and more time advising.
