7NXT // Senior Data Analyst - Marketing Strategy & Insights (m/f/d)

Your Impact

As our Senior Data Analyst - Marketing Strategy & Insights (m/f/d), you will partner with Marketing & Product Managers and Heads of Marketing across 7NXT's multi-brand portfolio (Gymondo, 7Mind and Buddyfit) to drive clarity, challenge assumptions and unlock smarter marketing decisions across all growth channels.

This role is not about dashboards or reporting. It's about marketing decision intelligence: helping our teams understand what's really driving performance, what to do next and where to invest.

You'll go deep into user behavior, experiment design and marketing effectiveness with a strong focus on causal measurement, incrementality and subscription-building insights.

• 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)

Communication & Influence

• Coach marketers to become more data-literate and hypothesis-driven

• Elevate data quality, methodology and standards across the team
