Junior AI Engineer / Data Scientist

Lund / Halmstad · Hybrid · Data/Engineering

At Effektify, we help companies make better marketing decisions by turning complex data into clear insights and useful actions. We are now looking for a Junior AI Engineer / Data Scientist to join our AI team and help build the next generation of AI and ML capabilities in the platform.

About the role

You will work across the full AI stack — from data pipelines, analysis, and model experimentation to product-facing AI features and agent-based workflows. The role is broad by design and gives you the chance to build practical experience across both engineering and data science in a real product environment.

You will not be expected to have done everything before. What matters most is that you have a strong foundation, enjoy solving problems, and are excited to learn by building.

What you will work on

Your work will include a mix of:

Building and improving data pipelines and workflows as data volumes and use cases grow

Developing AI features and agent-based workflows that turn connected data into clearer recommendations, insights, and next steps

Working with data from ad platforms, analytics tools, e-commerce systems, and financial systems

Taking ideas from exploration to production together with product and engineering

Examples of projects and focus areas

In the first phase, your work may include areas such as:

Help build functionality that uses campaign, conversion, sales, and business data to surface clearer recommendations on what to prioritise, investigate, or act on next.
