To continue this incredible adventure, we are currently looking for a Sr. Marketing Strategy Manager to join our talented Growth & Marketing team. This is a full-time position based at our Berlin HQ , with a hybrid setup of 3 office days per week. Reporting directly to our Director of Growth & Marketing , you will act as the analytical backbone of the Marketing & Growth function. Through a mix of cross-functional collaboration and direct ownership, you will use data to drive the strategy and performance of our marketing across all channels. Your scope is broad: from delivering our marketing data strategy and onboarding new tooling, to building out reporting, owning analysis, and launching your own performance-improving initiatives. This is a high-leverage role where your work directly shapes how we acquire customers and scale efficiently. 🎯 What you will own & build: Marketing Data Strategy: Help deliver our marketing data strategy, including the onboarding of new marketing data tooling and the refresh of our MMM/MTA capabilities with an external partner.

Analysis & Insight: Own the analysis across the Growth & Marketing function, self-serving your own data and answering the questions that matter most to our commercial performance. CAC & Spend Optimization: Build our understanding of marginal CAC and how to maximize spend across channels - scaling efficiently while improving performance. Decision-Making & Initiatives: Go beyond analytics production - own decisions off the back of your analysis, and start and deliver your own initiatives that improve marketing ROI. Cross-Functional Collaboration: Work closely with Growth & Marketing, Category Management, Commercial Strategy, and Product to make data the driver of commercial decisions. 🤝 What you bring: SQL Mastery: Strong experience writing complex SQL (BigQuery, Snowflake, Redshift, or similar) - you pull your own data and self-serve your own answers in the data warehouse.

Cross-Functional Fluency: A track record of working effectively across teams and translating data into action for commercial stakeholders. Mindset: Curious, commercially minded, approachable, collaborative, and an effective builder. Bonus Points: Experience with Snowflake, DBT, and Looker, and an understanding of the mechanics of key performance marketing channels (Google Shopping, Meta Ads, TikTok Ads, etc.). 🚀 The Grover Way - How We Drive Success: Own It: We take ownership seriously and define what success looks like. We drive shared ownership and don't wait - we drive. We keep one another accountable and take responsibility when issues arise. Challenge, Decide, and Commit: We engage in proactive support, active listening, and healthy conflict to reach the best outcomes. We value diverse perspectives and, once a decision is made, we commit to it fully. Empower and Grow: We enable, tru…
