We’re looking for a Growth Marketing Manager to own and optimize our end‑to‑end marketing engine—from partner co‑marketing and paid performance to brand campaigns, website experiments, and mobile‑app growth.

We’ve built a world‑class product suite—Letters, Memory Books, Community—and partnered with top organizations (Navy Federal Credit Union, Red Cross, and many more) to deepen our impact. Now, we need a Growth Marketing Manager who lives and breathes acquisition experiments, marketing funnels, and cares as deeply about our customers as you do activation, retention and new sign‑ups.

In this hands‑on role, you’ll own the end‑to‑end growth roadmap across paid, owned, and earned channels. From A/B testing our welcome flows with lifecycle marketing to scaling paid‑social at sustainable CAC, you’ll collaborate with teams like Product, Engineering and Ad Operations to turn data into playbooks—and playbooks into exponential user growth.

• Hyper‑growth phase: We’re scaling from 700k to 1m+ active users this year, and our current operations need structure, velocity, and surgical optimization.
• New product launches: Memory Books and premium Community features are live—time to drive self‑serve conversions at every stage of the funnel.
• Reactivating paid channels: We’ve neglected most paid search / social over the past year; it’s time to rebuild, re‑test, and systematically scale these acquisition levers.
• Cross‑functional alignment: We need someone who can serve as the glue between each team to ensure everyone’s efforts are coordinated, on‑time, and driving toward shared KPI targets.
• Strategic Partnership Coordination: Manage and coordinate partnerships across Army, Air Force, Navy, and commercial partners—aligning co‑marketing campaigns, joint activations, and demand‑gen initiatives.
• Content Marketing Optimization: You’ll own our website and blog end‑to‑end. You’ll revive neglected posts, optimize for AI‑driven search and SEO, tune headlines, experiment with new formats, and iterate based on engagement metrics so the blog becomes a true lead‑generation engine.

• Architect and execute co‑marketing campaigns internally and with partners
• Plan, launch, and optimize paid‑media across Meta, Google Ads, DSPs, and in‑app channels
• Lead brand initiatives—from concept through creative development and asset production (ads, video scripts, landing pages, print inserts)
• Drive website and mobile‑app growth via experimentation, funnel optimizations, and feature launch support
• Own end‑to‑end attribution and segmentation by managing our MMP and CDP (mParticle)
• Draft headlines, body copy, and CTAs; produce quick‑turn prototypes and layouts in Figma or Adobe Suite to support campaigns
• Plan, coordinate, and optimize all promotions—seasonal offers, partner co‑promos, referral incentives, in‑app and email blasts—to drive spikes in awareness, sign‑ups, and revenue
• Build and maintain dashboards in GA4, Looker and/or Looker Studio
• Craft slide decks and deliver regular presentations on performance, forecasts, and insights to stakeholders and leadership

• 5+ years in growth or performance marketing roles for mobile‑first or app‑centric products
• Proven…
