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
This is a junior, hands-on role across AI Engineering and Data Science. You will join a small AI team and work closely with Max, our AI Lead, Martin, our CTO, and other developers and technical colleagues across the broader tech team.
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
Supporting the design, testing, and refinement of 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
Help 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
Support work on models and logic that help the platform identify meaningful changes, rank what matters most, and explain why performance is moving.
Agent-based workflows for insight automation
Contribute to 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.
About the team and work culture
You will join a small AI team and be part of a broader tech organisation, which means short paths, broad scope, and close collaboration across product and engineering.
A large part of the broader tech team is based in Halmstad (our HQ), while Max is based in Lund. For that reason, Halmstad and Lund are especially relevant locations for this role. At the same time, we are flexible around remote and hybrid setup.
At Effektify, we value clear thinking, low prestige, and useful discussions. We care about quality, progress, and building things that hold up in practice. This is a good environment if you are curious, forward-leaning, and motivated by learning fast in a team where ideas are shared openly and responsibility grows quickly.
Who we are looking for
Required
0-2 years of experience in AI, machine learning, data science, or closely related work — or strong relevant internship or project experience
Strong skills in Python and SQL
Experience with one or more ML frameworks such as PyTorch or TensorFlow
Strong understanding of statistics and machine learning fundamentals
Comfortable using AI tools to support your work
Fluent English, written and spoken
A strong interest in learning new technologies and developing quickly in a practical environment
Preferred
A Master’s degree in mathematics, physics, machine learning, computer science, or a related field
Experience working with marketing, e-commerce, or other high-volume behavioural data
Experience with TypeScript or JavaScript
Swedish language skills
