Creative Data Analyst

Who are we?

At Publicis Groupe, we work around the needs and desires of our clients. We operate as one organization and under one P&L, integrating our specialties. This allows us to fulfil our clients' needs in creativity, media, technology, data, and production. We collaborate in multidisciplinary teams, giving our clients access to all our talents, expertise, and tools, both locally and internationally. This enables us to deliver integrated creative marketing and technology solutions where quality, speed, and cost are prioritized for our clients.

The role

We’re looking for a Creative Data Analyst to support the global creative-intelligence program for Mars (Pet & Snacking) as part of the Creative Engineering Workstream.
You will work across creative asset libraries, media plans, brand-lift data, and platform analytics to identify what makes content perform - then package those findings into clear, repeatable guidance for markets, creatives, and strategists.

This is a hybrid analytical and operational role: you’ll clean and merge datasets, code creative attributes, test and scale statistical models, and assist with making dashboards, cheat-sheets and playbooks that help 70+ markets improve asset effectiveness.

Why this role matters

• You will be building the intelligence layer that enables Mars to design smarter, faster, more effective creative—not just in one market, but globally;
• Instead of analysing “one campaign at a time,” you will help build a scalable system that is continuously learning from thousands of assets over hundreds of campaigns.

Creative Engineering Workstream

You will join a dedicated workstream that combines data engineering, creative scoring, media performance, and brand-lift modelling into a single intelligence layer. This workstream powers use cases such as:

• Identifying creative elements that correlate with lift in penetration, sales, and brand metrics;
• Standardising creative taxonomies and metadata ingestion;
• Automating mid-flight insights for media and creative teams;
• Reducing manual post-campaign analysis for 70+ markets;
• Building “what good looks like” frameworks for future asset development.

Key responsibilities

1. Creative Data Structuring

• Assign and validate creative attributes across large asset libraries (via Python/SQL + computer-vision tools);
• Maintain consistency in metadata, taxonomies, and tagging across markets and formats;
• Support ingestion of new datasets from partners (CreativeX, VidMob, Kantar, RealEyes, etc.);
• Lead exploration of emerging creative-tech tools and methodologies.

2. Insights & Analysis

• Analyse media & creative performance to spot patterns (platform × format × objective × audience);
• Conduct descriptive + exploratory analysis to understand what drives uplift in key metrics;
• Act as the local bridge between creative, media, and data teams. Bringing insights into workshops and ideation sessions;
• Run hypothesis testing and build regression/forecasting models where relevant;
• Support mid-flight insight generation for high-priority campaigns.

3. Integration & Automation

• Combine creative, media, and brand-lift data using SQL/Python;
• Build and maintain datasets powering dashboards and internal reporting views;
• Identify manual tasks that can be automated (tagging, refreshes, ingestion checks).

4. Output & Storytelling

• Turn analyses into 1-page outputs, benchmarks, “what good looks like” frameworks, and creative cheat-sheets;
• Present findings to strategy, creative, and media teams in a clear, non-technical way;
• Translate global learnings into actionable local strategies, ensuring cultural relevance and creative resonance;
• Help scale learnings to new markets, brands, or platforms;
• Represent the workstream in client-facing innovation sessions and internal knowledge-sharing forums.

What are we looking for?

• 2–4 years of analytical experience in marketing, advertising, or creative-effectiveness work;
• Strong skills in Python and/or SQL for data manipulation and analysis;
• Familiarity with statistical testing and regression methods;
• Experience working with media or creative datasets (paid social, video, display, etc.);
• Ability to turn complex data into simple, structured insights for non-technical audiences;
• Bonus: exposure to object-recognition tools (Gemini), CreativeX/VidMob, or brand-lift datasets.

What can you expect from us?

• A team that fully utilizes your skills and talents, and where you can learn a lot from experienced teammates;
• A broad role with plenty of learning and growth opportunities;
• Various training and development options;
• A competitive salary with excellent secondary benefits;
• A super friendly office where you can bring your dog, featuring a beautiful terrace and our own bar on the 6th floor;
• Tasty lunches and drinks (Thirsty Thursdays and Friday drinks!);
• The Work Your World Program: the chance to work from anywhere in the world for 6 weeks a year;
• Discounts on ClassPass, a bike plan, and a clothing repair service;
• A work environment where everyone feels heard, valued, and respected.
