AR & Billing Specialist

About Darkroom

Darkroom (Darkroom Digital, Inc.) is the leading next-generation growth marketing firm engineering the brands of tomorrow. Founded in 2017, we set out to redefine what a modern agency could be, by replacing the inertia of legacy advertising behemoths with a model built for speed, intelligence, and measurable impact.

At our core, Darkroom is a human services company powered by Shadow, a universal AI commerce layer that integrates executive-level strategy with proprietary agentic technology. This fusion enables our teams to deliver outsized returns by enhancing creative output, operational efficiency, and revenue generation across every stage of the customer journey.

Our track record speaks for itself: billions in attributable revenue driven across e-commerce marketplaces, media networks, DTC ecosystems, and social commerce platforms. Every engagement feeds into our proprietary data infrastructure, enabling a continuous feedback loop that accelerates growth, improves margins, and compounds results across our client portfolio.

What began as a boutique design studio has evolved into one of the fastest-growing private companies in America (Inc. 5000) and among the most effective performance media agencies of the 2020s (Varos). Our founders were recognized by Forbes 30 Under 30 for advancing the intersection of technology, marketing, and advertising, cementing Darkroom’s role as a defining player in the future of media innovation.

About the Role

Darkroom is hiring an AR & Billing Specialist to join the Finance team. You’ll own billing, collections, accounts payable, creator payments, and cash visibility across more than 80 client accounts and around 100 invoices a month. You’ll report to the SVP of Finance and work closely with the Finance Operations Manager, who sets our collections strategy, as well as our account leads and external bookkeeper.

This is not a reminder-sending role. We want someone who knows every account, spots payment risk early, and decides how to approach each client so we get paid on time without damaging the relationship.

This role is built for someone who sees AI as a core part of how finance gets done. You’ll use tools like Claude to check calculations, automate repetitive billing and follow-up work, and build workflows that raise both the speed and accuracy of our output.

This is a fully remote role supporting a team in the EST time zone (9 AM–5 PM EST).

What You’ll Do

• Prepare and issue all client invoices each cycle, including recurring retainers, one-off projects, variable and performance fees, and hourly web-support work.

• Reconcile tracked hours and variable-fee calculations against contracts and scopes before invoices go out.

• Keep the billing schedule current as clients start, change scope, pause, or offboard.
