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 Senior 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

This is a senior, hands-on role across AI Engineering and Data Science, where you will work closely with Max, our AI Lead, and Martin, our CTO, in a small team with broad scope and a high degree of ownership.

You will work end-to-end, from data and ML infrastructure to modeling, experimentation, evaluation, and product-facing AI features.

What you will work on:

Your work will include a mix of:

Building and improving data and ML infrastructure as data volumes and use cases grow

Designing, testing, and refining models, algorithms, and decision logic used in the product

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:

Recommendation features based on connected performance data

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

Detection of shifts, anomalies, and performance drivers

Improve how the platform identifies meaningful changes, ranks what matters most, and helps users understand why performance is moving.

Agent-based workflows for insight automation

Build systems that combine platform data, AI models, and product logic to automate parts of the insight work and help users move faster from data to action.
