Platform Engineer
PLATFORM ENGINEER
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.
