Job description

As a Senior Data Analyst in the Funnel Efficiency & Conversion Rate Optimization team, you will play a key role in driving data-based decisions across our e-commerce operations. This isn't just about reading reports - we are looking for an experienced analyst who can build analytical processes from raw events to high-level strategic insights.

Our team is responsible for optimizing the traffic and conversion across all Allegro markets. Our goal is to transition to an “AI-first” model and achieve full automation of analytics. The new analyst will join the team of experienced analysts and serve as a key insights provider for performance marketing teams. You’ll also become the technical owner of projects such as Automated Anomaly Detection, Advanced Decomposition of Conversion Factors, and more, and you’ll work with us to develop the Google Looker BI tool.

Your main responsibilities:

Traffic and Conversion Analysis: Analysis of visits, conversion rate and transactions broken down by external traffic sources for 4 markets

Strategic Business Partnering: Acting as a dedicated analytical partner for performance marketing and growth teams (including PPC, SEO, MA, affiliate and app marketing), translating complex data into actionable business recommendations

Marketing & Customer Value Analytics: Developing and refining marketing attribution frameworks, analyzing Customer Lifetime Value (CLV), and evaluating campaign performance to support optimal budget allocation

BI & Self-Service Analytics: Leading analytical initiatives to build, optimize, and modernize reporting environments (including Looker) to empower business stakeholders with clear, interactive data visualizations

Data Quality & Anomaly Detection: Monitoring traffic health, analyzing bot patterns, and identifying data anomalies to maintain high data purity and reliable reporting

Ad-hoc & High-Impact Projects: Delivering fast-paced analytical support and actionable insights for strategic cross-functional initiatives and new product or commercial launches

Data Pipelines & Automation: Creating and optimizing automated reporting cycles and data workflows to streamline analytical processes and ensure efficient data delivery

This is the right job for you, if you:

Have strong experience in Data Analytics within E-commerce and/or Digital Marketing areas

Are proficient in SQL and experienced in working with BigQuery in Google Cloud Platform

Have hands-on experience with Apache Airflow for orchestrating and automating data workflows

Possess fluent English skills (B2 level) with proven confidence in presenting data insights to Senior Leadership and Executive Teams

Combine deep analytical skills with a proactive, PM-like approach – adept at managing multiple stakeholders, gathering requirements, and turning complex data into clear business recommendations

Hold a degree in a quantitative field (e.g., Mathematics, Economics, Statistics, or similar)

Are familiar with BI tools such as Looker or Tableau (experience in Looker migration is a big plus)

Have a basic understanding of marketing attribution concepts

Are open to leveraging AI tools (e.g., Gemini, Copilot, ChatGPT) to boost daily analytical efficiency and coding workflows

What we offer:

Employment contract for a temporary replacement period (maternity cover)

Flexible working hours in the hybrid model (4d office/1d home) - working hours start between 7:00 a.m. and 10:00 a.m. We also have 30 days of occasional remote work

A great learning opportunity, working with people coming from a lot of experience in top tier strategy consulting and e-commerce space

Well-located office in Warsaw (with e.g., fully equipped kitchens, bicycle parking, terraces full of greenery) and excellent work tools (e.g., raised desks, ergonomic chairs, interactive conference rooms)

A wide selection of fringe benefits in a cafeteria plan - you choose what you like (e.g., medical, sports or lunch packages, insurance, purchase vouchers)
