Senior Marketing Business Intelligence Analyst

As a Senior Marketing Data Analyst in the Marketing Analytics team, you will own the Virality Analytics space, focusing on our Referral / Refer-a-Friend (RAF) programs across 12+ HelloFresh markets and multiple brands. You will be the analytical voice behind referral products, shaping how we measure them, how we grow them, and how we prove their value to the C-suite.

What you'll do

• Act as the trusted analytics partner to the Virality Marketing, CRM, and Growth stakeholders — translating broad, ambiguous business questions into structured, prioritized analytical work
• Own the Virality marketing reporting (WBRs, QBRs and Forecasting) as well as funnel-level diagnostics across sender and friend journeys
• Represent Virality analytics in cross-functional forums with Product, Marketing, Data Engineering, CRM Ops, and Finance
• Co-design, quality-control, and analyze A/B tests on referral incentive structures, entry points, share flows and CRM comms
• Apply rigorous experimentation methodology — power analysis, primary metric selection, guardrail metrics, sample-size-aware interpretation
• Analyze customer value contribution using MPC2 predictions, sender-reward cost, friend-discount cost, and cost-per-conversion economics
• Mentor more junior analysts on structured problem-solving and stakeholder communication

What you'll need

• 6+ years of experience in Marketing, Product, or Customer Analytics — ideally in a fast-paced B2C, subscription, or growth-oriented business
• Advanced SQL proficiency — comfortable with window functions, CTEs, complex joins, and performance-tuning queries on large event-level tables
• Strong hands-on experience with A/B testing design and analysis, including statistical significance, power, guardrails, and small-sample handling
• Proven ability to build and maintain BI dashboards (Tableau, Databricks, or similar) that reach senior leadership
• Experience designing and working with GenAI designed end to end workflows from problem definition to documentation and creating reproducible research
• Strong problem-solving skills with a track record of translating ambiguous business challenges into structured, data-driven projects
• Excellent stakeholder management skills, with experience influencing cross-functional Product, Marketing, and Engineering partners

Nice to have

• Prior experience with referral / virality / growth-loops programs, or with acquisition-channel economics (CAC, LTV, ROI)
• Experience with CRM analytics (email, push, in-app) — including deliverability, engagement, and unsubscription guardrails
• Python for data transformation, ad-hoc analysis, or lightweight modeling
• Familiarity with Databricks / Spark SQL, dbt, or similar modern data-stack tooling
• Experience with Statsig, Optimizely, or similar experimentation platforms

What they offer

• Modern working space in Berlin-Kreuzberg with flexible working hours and Work From Home/Work from Abroad options
• Discount for HelloFresh boxes and Convini products
• Development possibilities with internal trainings and yearly Learning & Development budget
• Home office setup budget and monthly transportation budget via NAVIT
• Well-being initiatives including Headspace, Spill, discounted fitness offers, and yoga classes
• Childcare and company pension scheme benefit
