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.
About the team and work culture
You will join a small AI team, which means short paths, broad scope, and plenty of room to shape both solutions and technical direction.
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.
Who we are looking for
Required
3+ years of experience in AI, machine learning, data science, or closely related work
Strong skills in Python and SQL
Experience with one or more ML frameworks such as PyTorch or TensorFlow
Experience building and shipping AI, ML, LLM, or agent-based functionality in production
Strong understanding of statistics and machine learning fundamentals
Comfortable working with Git
Fluent English, written and spoken
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 AWS
Experience with Snowflake or modern data warehousing
Experience with TypeScript or JavaScript
Swedish language skills
Experience from a startup, scale-up, or other growth-stage environment, or a strong interest in working in that kind of setting
More about Effektify
Effektify (www.effektify.com) is a profitable scale-up with 50+ employees and 400+ customers. Since 2021, we have grown from a small founding team into a multi-office company with strong momentum, a working product, and a lot of room to shape what comes next.
At Effektify, we help companies understand what drives marketing performance and what to do next.
Our platform brings together data from sources such as Google, Meta, LinkedIn, TikTok, analytics tools, Shopify, WooCommerce, and financial systems. That creates a rich data environment across spend, traffic, conversion, revenue, and business performance.
For you, that means access to large and varied datasets, connected across several domains, and a chance to work on technically demanding problems with clear business relevance. It also means building product features where improvements can quickly reach customers and make a visible difference.

Location: Flexible hybrid setup, with a preference for Lund or Halmstad. We also have offices in Stockholm, Gothenburg, and Jönköping
