Retention Specialist

About Darkroom

Darkroom 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

We are hiring a Retention Specialist — a strategic, hands-on lifecycle marketer with a proven track record in email and SMS for DTC brands. You'll partner closely with Associate Directors of Retention and cross-functional teams to develop and deploy high-performing campaigns for some of the fastest-growing DTC brands in the world — translating data into strategy and strategy into revenue.

Darkroom is a career accelerator for marketers who want to operate at the intersection of creativity, commerce, and performance - while mastering the tools and tactics of modern CRM strategy.

• Contribute to monthly retention marketing calendars and proactively bring creative campaign concepts to clients and internal teams.
• Lead portions of client calls - presenting content ideas and managing the revision and approval process with confidence.
• Partner with the in-house design team to shape the creative direction of campaigns and flows, ensuring visual and copy are working together to drive results.
• Build, audit, and optimize automation flows, pop-up logic, segmentation strategies, and app integrations.
