## Company Description

## Job Description

At SIXT, data is at the heart of every smart marketing decision. As part of our Marketing Analytics team, you will work at the intersection of advanced statistical modelling, causal inference, and performance marketing — helping us understand the true impact of our investments and steer budgets more effectively across channels. You will collaborate with marketing stakeholders and cross-functional partners to turn complex model outputs into clear, actionable insights. If you’re passionate about using cutting-edge methods to solve real business problems, join Team Orange and apply now.

**YOUR ROLE AT SIXT**

– You uncover the true incremental impact of marketing investments using experimental and quasi-experimental methods — including Difference-in-Differences, Interrupted Time Series, and Bayesian Structural Time Series — to establish causal evidence where traditional A/B tests are impractical or unavailable
– You develop and maintain proprietary response-curve and elasticity models to reduce reliance on platform-native estimates and support better budget allocation decisions across channels and campaign types
– You support the development and maintenance of a Marketing Mix Model (MMM), contributing to model specification, prior elicitation, and validation, and translating outputs into actionable budget allocation recommendations
– You help extend the team’s bid-target steering framework beyond Google Search Ads to channels such as Display, Meta, and Bing Ads, adapting modelling approaches to each channel’s measurement and data characteristics
– You explore and evaluate data-driven attribution approaches, using web behavioural data to understand the customer journey and benchmark against existing third-party attribution
– You present model findings clearly to marketing and cross-functional stakeholders, contributing to internal dashboards and Streamlit applications that operationalise your work

**YOUR SKILLS MATTER**

– **Statistical Modelling & Causal Inference:** You have a solid grounding in Bayesian methods, causal inference (e.g. DiD, Interrupted Time Series, BSTS), and quasi-experimental design; familiarity with PyMC or comparable probabilistic programming tools is a strong plus
– **Python & Data Stack:** You are proficient in Python with hands-on experience using Pandas, NumPy, Scikit-learn, and visualisation libraries such as Matplotlib and Plotly, comfortable working in both notebooks and production codebases
– **SQL & Cloud Infrastructure:** You bring strong SQL skills and practical experience querying large datasets in AWS environments, ideally using Athena or Redshift; familiarity with Airflow or similar orchestration tools is a plus
– **Machine Learning:** You have a solid understanding of supervised and unsupervised ML techniques, model evaluation, and how to take a model from experimentation to a reliable, maintainable production output
– **Online Marketing Knowledge:** You are familiar with paid search and/or display advertising — including how campaign structures work, what tROAS and tCPA mean in practice, and how performance marketing metrics connect to business outcomes
– **Communication & Collaboration:** You can translate complex model outputs into clear, actionable narratives for marketing and business stakeholders; experience with Streamlit or a comparable dashboarding tool, as well as GenAI-assisted development approaches such as Spec-Driven Development, is a plus

**WHAT WE OFFER**

– **A Global Tech Hub in Lisbon** Join a thriving international tech community and work alongside engineers, product experts, and business teams who turn ideas into real impact. Our hubs at Factory Lisboa in Beato and ARTs Lisboa in Parque das Nações are where great tech gets built
– **Learning & Knowledge Exchange** Level up through regular events with internal and external speakers. We value curiosity, continuous learning, and open exchange – across teams, disciplines, and borders
– **Flexible Work Setup** Two office days a week, flexible hours, and modern spaces built for both deep focus and team collaboration – work the way that brings out your best
– **Time Off & Wellbeing** Enjoy 28 vacation days per year, an additional day off on your birthday, one volunteer day annually, and private health insurance that also covers your spouse and children free of charge
– **Practical Everyday Benefits** Get a yearly Coverflex allowance and a daily meal allowance to make everyday life a little easier
– **SIXT Perks** Get exclusive rates on all SIXT services, with special discounts extended to your family and friends. Because great perks are even better when you can share them

– Quality Assurance: Act as the lead technical reviewer for complex DAX, data models, and code merges, ensuring “pixel-perfect” and performant delivery.
– Al-Augmented Development: Lead the adoption of Al tools (Copilot in Fabric/Power BI) to accelerate DAX generation and documentation, tracking efficiency gains.
– Visual Governance: Enforce the ‘Mockup-First’ methodology, ensuring no development begins without a signed-off prototype from the UX/UI team.

## Qualifications

**Must-Have Technical Skills:**

– Power BI Mastery: Expert-level capability in DAX, Power Query (M), and calculation groups. You must be able to debug the most complex performance issues.

– Code-First BI Experience: Hands-on experience with Tabular Editor, TMDL, and Git integration.
– Data Modeling: Deep expertise in Star Schema design and Kimball methodologies.

**Broad Data Ecosystem Knowledge:**

– Proven experience connecting BI tools to non-Microsoft sources (e.g., Databricks Lakehouse, Google BigQuery, AWS Redshift). You understand the nuances of Direct Query vs. Import in these scenarios.

**Nice-to-Have Skills:**

– Tableau: Experience designing and deploying Tableau solutions (to support agnostic client requests).
– Python: Ability to use Python for light data engineering or scripting.
– dbt: Familiarity with dbt for transformation layers.

**Soft Skills:**

– Commercial Acumen: Experience in consulting pre-sales, commercial modeling, and writing proposals.
