AI ENGINEER PERSONALIZATION

Stockholm On-Site Full-Time Immediate Start

Who We Are

We are a well-funded early-stage technology company on a mission to fundamentally redefine the way the world searches discovers and transacts built on a philosophy that puts the user first at every step.

The user is not simply a means of transaction. They are a valued participant whose data works for them not against them enriching their world and their own experience within it with them retaining full control.

Our mission is underpinned by proprietary patent-pending technology built on a novel engine and system.

The Problem You Will Be Solving

The internet was built to inform the many not to serve the individual. Platforms optimize for engagement extraction and consumption at global scale. AI has made this model even more efficient with the user still largely remaining the input not the full beneficiary.

The problem is not information. The world has never had more. The problem is that people give away a lifetime of data without receiving the personalized experience it should enable.

People should not have to search. They should simply find.

Who You Are

Highly talented and motivated to build products with people for people

You thrive in zero-to-one environments and find genuine satisfaction in creating from scratch

A fast-paced thinker with a relentless desire to learn improve and raise the standard around you

Able to inspire elevate and collaborate; you make the people around you better

A great communicator; you express complex ideas with clarity precision and confidence across all levels of the organization

Able to transform ideas into working systems and technical milestones with light speed and precision

Highly ambitious and action-driven; you thrive under pressure and find genuine energy in working at the edge of what is considered possible

Capable of designing and building production-grade systems in a fourth of the time most experienced and sane professionals would consider possible

What You Will Do

Build personalization systems that combine behavioral modeling dynamic user representations and real-time context-aware content delivery

Design and operate feature engineering pipelines that transform high-volume behavioral event streams into model-ready inputs within the latency and reliability constraints

Build recommendation systems that scale seamlessly from cold-start to data-rich production environments without requiring architectural changes

Implement exploration-exploitation frameworks such as contextual bandits online learning or reinforcement learning approaches that continuously optimize content delivery without heavy offline retraining cycles

Build feedback and learning infrastructure that translates user interactions into measurable model improvements on a continuous basis

Design evaluation frameworks capable of distinguishing genuine personalization quality from overfitting to easily measured proxy metrics

Requirements

Minimum Qualifications

MSc in Machine Learning Computer Science Statistics or a directly related quantitative field from KTH Chalmers ETH Zurich EPFL or an institution of equivalent standing

Deep theoretical and applied understanding of recommendation systems; has implemented methods from the literature and shipped them to real users

Experience with sequential modeling applied to user data; recurrent architectures attention-based sequence models or equivalent

Production ML engineering discipline; code that serves reliably in production not only evaluates well in notebooks

Demonstrated ability to take a recommendation system from research to production

Preferred Qualifications

PhD in Machine Learning Computer Science or a directly related quantitative discipline; given significant weight in our assessment

Research depth in recommendation sequential modeling or online learning

Experience with privacy-preserving approaches to behavioral modeling

25 years of experience; exceptional graduates assessed on equal terms with experienced engineers

A body of independent work; published research open source contributions or personal projects that demonstrate what you build without instruction
