• Combine deep analytical skills with a proactive stakeholder management approach.
• Understand marketing attribution concepts.
• Are open to using AI tools (e.g., Gemini, Copilot, ChatGPT) to boost daily efficiency.

What we offer:

• 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

• English classes that we pay for related to the specific nature of your job
• A training budget and an internal learning platform where you will find multiple trainings
