Lead Data Scientist- Join AIDA Growth

Location: Bucharest, Romania

Who We Are

Hi, we are AIDA — we believe that great marketing is data-driven, customer-focused, and measurable.

Our mission is to help businesses grow by making smarter decisions and creating real connections with their audiences.

About the Role

We are looking for a Lead Data Scientist — not just someone who can build models, but someone who knows how to ask the right questions, challenge assumptions, and turn data into insights that matter.

This is a role that combines strategy and hands-on execution. You will lead the data science work across projects, ensuring the right questions, methods, and outcomes.

You’ll have ownership and autonomy in the analytical process, while working closely with the team — in a hybrid setup, combining remote work with in-person meetings in Bucharest when needed.

If you enjoy leading, thinking, and doing — and if you care about both precision and relevance — we’d love to meet you.

What you’ll be doing

  • Lead the analytical stream of projects, from design to delivery

  • Define the right questions, choose the appropriate methods, and validate results

  • Collaborate with data engineers to ensure data quality and preparation

  • Guide data analysts on supporting analyses, queries, reports, and visualizations

  • Connect data insights to business decisions — clearly and effectively

  • Document each step: assumptions, methods, results, next steps

  • Stay curious: explore new ideas, tools, and techniques in data science and AI

What we’re looking for

  • 5+ years of experience in data science, predictive modeling, or applied analytics

  • Proven ability to lead projects or analytical workstreams

  • Strong skills in Python and SQL, with experience using libraries like pandas, scikit-learn, numpy, etc.

  • Solid understanding of statistics and machine learning techniques

  • Comfortable working with real-world, messy, incomplete datasets — and finding practical solutions

  • Clear, structured, and persuasive communication skills

  • Business mindset — you understand how data connects to real decisions and outcomes

  • Bonus: experience with marketing data, segmentation, or engagement metrics

What We Offer

  • Freelance / part-time engagement, flexible schedule

  • Hybrid setup: remote work combined with in-person meetings in Bucharest when needed

  • Autonomy, ownership, and the space to do your best work

  • Projects that respect your time, skills, and expertise — no micromanagement

  • A team that values curiosity, clarity, and meaningful work over buzzwords
