Senior Growth Marketing Manager

Beam is hiring a Senior Growth Marketing Manager to own and expand its paid marketing channel portfolio. The role involves building new acquisition channels from the ground up, managing budgets and performance, implementing tracking and measurement, and using data to guide channel investment decisions.

Responsibilities:

• Maintain a live pipeline of untested channels with a prioritized case for each — Reddit, Pinterest, direct mail, CTV self-serve, streaming audio, sampling, comparison and marketplace placements, co-marketing, whatever the category hasn't figured out yet
• Run each new channel as a real experiment: sized hypothesis, committed test budget, tracking and measurement stood up before spend starts, defined kill criteria, and defined graduation criteria
• Own the unglamorous parts of standing up a channel — vendor diligence, contracts and insertion orders in partnership with Legal, UTM and promo code taxonomy, pixel and postback implementation, reporting that connects to Shopify
• Write the playbook for every channel you prove out so it can be handed off, staffed, or scaled without you being the single point of knowledge
• Say no to your own ideas quickly. Most tests won't work, and the value of this role is how cheaply and honestly you learn that
• Own CAC, contribution margin, and new customer volume for every channel in your portfolio, with a defensible view of incrementality rather than a platform-reported number
• Work in Shopify as source of truth and know exactly where and why platform reporting diverges from it
• Build the reporting yourself — weekly channel reads, monthly incrementality and cohort views, and a clear forecast you're willing to be held to
• Bring the allocation argument, not just the report: where the next dollar should go, what it's coming out of, and what you expect it to return
• Flag data quality problems before they become decisions. Tracking gaps, promo code leakage, and attribution artifacts are yours to catch

Requirements:

• 5+ years in growth, performance, or acquisition marketing at a DTC, subscription, or ecommerce brand
• Hands-on ownership of at least one of digital marketing channel and demonstrated range across several other channels — we're hiring a generalist, not a specialist
• A real 0→1 story: a channel you started from nothing and grew into a meaningful, forecastable line. Be ready to walk through the first $10K, what you got wrong, and how you knew when to double down
• Strong analytical chops. Comfortable in spreadsheets at a level most marketers aren't, fluent in cohort and LTV:CAC thinking, and appropriately skeptical of last-click attribution
• Agency and vendor management experience, including negotiation and the willingness to hold a partner accountable or replace them
• Scrappy and self-sufficient. You build the tracking, write the brief, pull the data, and make the deck — and you don't wait for a process to exist before you start
• Direct communicator who can make a clear recommendation under uncertainty and change position when the data changes
• Location: Boston, MA or New York, NY (Hybrid, 2-3 days/week in-office) or Remote
