NXT​/Senior Marketing Decision Analyst

Your Impact

As our Senior Marketing Decision Analyst (m/f/d), you will partner with Marketing & Product Managers and Heads of Marketing across 7

NXT’s multi-brand portfolio (Gymondo, 7

Mind 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.

• 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

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

• 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

• 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

• 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
