About The Position

ProSomnus Sleep Technologies is a medical device company focused on precision oral appliances for the treatment of obstructive sleep apnea and snoring. We manufacture custom devices prescribed by dentists and sleep physicians, and we partner with dental practices across the country. Our finance team supports a growing organization with a strong emphasis on disciplined processes, clean documentation, and audit-ready records. This role begins with a focused scope on cash applications and broader Accounts Receivable support, with a clear opportunity to grow into a more typical collections role over time. To start, you will help match and apply incoming customer payments, research unapplied cash and discrepancies, and keep clean supporting documentation. As you build fluency in our systems and process, the role can expand into customer outreach, aging follow-up, and dispute resolution. This is a learning-focused position designed for a student or early-career candidate who wants hands-on exposure to the order-to-cash cycle in a real finance organization. You will work closely with the General Ledger Accountant.
