Senior Marketing Decision Analyst (m/f/d)

Your Impact

At 7NXT (Gymondo, 7Mind, Buddyfit), we use data to drive how millions of people build healthier routines.

As our Senior Marketing Decision Analyst , you partner closely with Marketing & Product Managers as well as Heads of Marketing across our multi-brand portfolio. You challenge assumptions, bring clarity into complexity and enable smarter investment decisions across all growth channels.

This role is not about reporting. It’s about decision intelligence : understanding what truly drives performance, what to do next and where to invest. Your work directly influences budget allocation, marketing efficiency and subscription growth across all brands.

Your Mission

Decision Intelligence & Strategic Sparring

• Act as a strategic thought partner in marketing decision-making
• Translate data into simple, actionable language: turn complexity into clarity
• Help prioritize investments, guide strategic bets and unlock growth

Impact Measurement & Causal Inference

• Move beyond attribution: measure true incremental impact
• Design structured experiments (e.g. geo splits, holdouts, uplift tests) and analyze results using robust statistical methods

Cross-Brand & Channel Insights

• Compare what works (and what doesn’t) across brands, markets and campaigns
• Identify repeatable growth levers and help to decide where budget should be invested
• Translate insights into actions for CRM, Paid Social, Search, Influencer and new growth channels

Experimentation & Behavioral Analysis

• Model user behavior, funnels, retention loops and conversion flows
• Own and evolve our experimentation practice (incl. CRO, AB tests)
• Use behavioral signals to improve creative strategy and campaign timing

Communication & Influence

• Tell stories that matter: explain what’s happening, why and what to do about it
• Coach marketers to become more data-literate and hypothesis-driven
• Elevate data quality, methodology and standards across the team
