- 4+ years of experience in marketing analytics, data science, or experimentation roles, preferably within performance marketing teams
- Proven expertise in incrementality measurement techniques, including geo experiments, conversion lift studies, synthetic control, or uplift modeling
- Strong proficiency in SQL and Python, including libraries for statistical modeling (e.g., causal inference packages like Meta GeoLift, Causal Impact etc.)
- Hands-on experience analyzing performance marketing channels such as Paid Search, Shopping, PMAX, SEO, App campaigns, Youtube, Meta, TikTok, Affiliates and Podcast
- Familiarity with A/B testing, media mix modeling, and attribution modeling frameworks
- Experience working with large-scale marketing datasets, visualization tools (e.g., Tableau, Looker), and cloud-based data platforms (e.g., Big Query and Google Cloud Platform)
- Excellent communication skills and a proven track record of:
- Translating complex data insights into business impact
- Educating non-experts about benefits of experimentation, being the go-to person about marketing tests, spread the “test & learn” approach in the organization
- Strong analytical rigor and judgment, including:
- Critical thinking and problem-solving skills
- Rigorous statistical capabilities and logical reasoning
- Experience with both qualitative and quantitative data analysis

- You will design and implement advanced incrementality measurement frameworks across performance marketing channels, including Paid Search, Shopping, PMAX, SEO, App campaigns, Meta, TikTok, Affiliates and Podcast
- Leveraging causal inference techniques such as conversion lift studies, geo experiments, and synthetic control, you’ll provide data-driven insights that directly inform budget allocation, campaign strategy, and growth decisions
- Design and execute incrementality measurement approaches (e.g., geo experiments, conversion lift studies, holdouts) to evaluate the true impact of digital marketing channels such as Paid Search, Shopping, PMAX, App campaigns, Youtube, Meta, TikTok, Affiliates and Podcast
- Build models to quantify incremental return on ad spend (iROAS), channel lift size and measure cross-channel interactions
- Develop frameworks to continuously monitor and optimize campaign performance based on causal impact rather than last-click attribution
- Collaborate with channel managers to translate insights into bidding strategies, budget reallocations, and creative optimizations
- Apply state-of-the-art causal inference methods (e.g., synthetic control, uplift modeling, difference-in-differences) to assess the impact of paid media strategies
- Create scalable and automated measurement pipelines in partnership with data engineering teams
- Contribute to the development of media mix modeling (MMM) frameworks to complement incrementality experiments
- Build predictive models for audience segmentation, conversion propensity, lifetime value (LTV), and bidding optimization
- Use time-series modeling and forecasting to predict performance trends and seasonality effects
- Ensure statistical rigor through robust model validation, assumption testing, and experimentation best practices
- Partner closely with performance marketing, finance, data engineering, and product analytics teams to build the experimentation calendar, align on measurement methodologies and KPIs
- Present complex analytical findings and experiment results to both technical and non-technical audiences, influencing marketing strategy and budget decisions
- Champion a culture of incrementality testing and data-driven decision making within the marketing organization (knowledge sharing, peer review)
Our take
At a time when new smartphones launch frequently but with fewer new features and when individuals want to contribute to sustainability and the circular economy, Back Market is setting out to provide customers with a viable option of purchasing refurbished electronics goods.
The vision of the company is to become the default choice when it comes to electronics purchases, irrespective of the customers' budget. In order to materialise this vision, Back Market guarantees that all the devices sold on its platform are 100% functional. The company screens sellers before allowing them to join its platform and it monitors their performance in real-time by collecting detailed customer feedback. By doing this, it hopes to restore trust in refurbished devices and to make sustainability an easy, safe, and affordable choice.
Back Market operates in 17 counties and has a client roster that includes Netflix, Disney, BBC, Sony, and Apple. The company has also raised over $1 billion in capital, which has been invested in expansion across new and current markets. And with the recommerce market only growing, Back Market has a lot of room for exciting future growth.
