Taxfix

OUR STORY: Every year millions of people are either filing their taxes in fear or giving up on their tax refund altogether. We're working on fixing that. Our intuitive app enables anyone, regardless of education or background, to file their taxes with newfound confidence. Spread across Germany, Spain and the UK, the team at Taxfix Group with its brands Taxfix, Steuerbot and TaxScouts, is a compassionate group of solution-finders. We speak our minds openly, and with over 400 professionals, including tax experts, developers, and IT security experts, we're rich in ideas and voices. The group has facilitated more than 3.5 billion euros in tax refunds for its customers since its founding in 2016. YOUR CHALLENGE: Join our Marketing Analytics team as a Marketing Scientist, where your mission is to build the measurement and modeling capability that decides how we grow. You will own how Taxfix measures marketing causally and turn that into production models that directly shape CLV, CAC, and revenue. Your output is durable measurement infrastructure and models that the Growth Marketing, CRM, and MarTech teams operate every day to scale efficiently in competitive markets. YOUR RESPONSIBILITIES AND DECISIONS: * Own and advance our marketing measurement stack (attribution, MMM, incrementality testing, brand tracking) and set the causal-inference standard the marketing organisation uses to make budget, channel-mix, and retention decisions. * Build production-grade models (CLV, demand forecasting, propensity) that feed live decisions such as budget allocation and channel mix, not one-off analyses. * Own the model lifecycle together with Analytics Engineering: reproducible pipelines, validation, monitoring, and retraining, so models stay trustworthy once they are in production. * Design and run experiments as a discipline (geo tests, holdouts, incrementality) and act as the arbiter when measurement approaches disagree. * Apply advanced statistical and machine-learning methods (regression, Bayesian inference, causal inference, forecasting) to turn ambiguous marketing questions into clear decisions that move CLV and reduce CAC. * Communicate results persuasively to technical and non-technical stakeholders and drive adoption of the recommendation across Marketing. * Build and bring AI-native analytics workflows (agentic data exploration, LLM-assisted causal analysis) into the team's everyday practice. YOUR PROFILE: *  3+ years in marketing science or marketing analytics with hands-on modeling, ideally in B2C acquisition and retention. * Deep with attribution, MMM, incrementality testing, causal inference, and experimentation design across digital paid channels (search, social, programmatic) and CRM. Exposure to offline and brand measurement (TV, CTV, podcast) is beneficial. * Strong statistical and machine-learning foundation (regression, Bayesian methods, classification, clustering, forecasting) applied to marketing use cases such as CLV prediction, demand forecasting, and pricing-elasticity models. * Has taken models to production: reproducible pipelines, validation, and monitoring, and is comfortable partnering with Analytics Engineering on deployment. Advanced SQL and Python, with dbt for data modeling. Comfortable communicating results in BI tools such as Looker. * Strong ability to connect analysis to CAC, CLV, and retention outcomes and guide acquisition and retention strategy. * Proactive and outcome-driven, comfortable owning work end to end from data pipeline to business recommendation that drives measurable impact. * Practical experience applying AI-driven solutions such as prototyping with LLMs (e.g. Claude Code, Gemini CLI), automating workflows (e.g. LangChain, n8n), and using AI-powered IDEs (e.g. Cursor) to accelerate analysis.   WHY TAXFIX? * A chance to do meaningful, people-centric work with an international team of passionate professionals. * Holistic well-being with free mental health coaching sessions and yoga. * A monthly allowance to spend on an extensive range of services that you can use and roll over as flexibly as you like. * Employee stock options for all employees—because everyone deserves to benefit from the success they help to create. * 30 annual vacation days and flexible working hours. * Work from abroad for up to six weeks every year. Just align with your team, and then enjoy your trip. * Plenty of opportunities to socialise as a team. In addition to internal tech meetups, our international team hosts regular get-togethers—virtually and in person when possible. * Free tax declaration filing, of course, through the Taxfix app—and internal support for all personal tax-related questions. * Have a four-legged friend in your life? We’re happy to have dogs join us in the office. Excited? So are we.
