The posting
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
What You Will Do • Design and build the core API platform and integration framework with strong versioning, consistency, and deep awareness of production consumer dependencies • Build extensible third-party integration frameworks that connect external services across multiple domains through clean, unified interfaces • Design and build unified identity and profile systems that deliver consistent, real-time user state across the platform • Build high-reliability event streaming infrastructure as the backbone for real-time data flows, with strong guarantees around ordering, consumer management, and failure recovery • Implement authentication and authorization infrastructure including OAuth 2.0, OIDC, fine-grained permissions, and secure multi-tenant access control suitable for consumer platforms with enterprise customers • Build enterprise integration layers with secure API surfaces and data exchange protocols that allow institutional customers to reliably embed platform capabilities into their own systems
Minimum Qualifications • MSc in Computer Science or Software Engineering from KTH, Chalmers, or an institution of equivalent standing • Demonstrated experience originating distributed system architectures; you have designed systems, not implemented designs made by others • Production experience building APIs that multiple consumers depend on; with experience managing the operational consequences of that dependency • Deep understanding of event-driven architecture and the consistency trade-offs inherent in distributed data synchronization
Preferred Qualifications • Background from Klarna, Tink, Trustly, Bambuser, or comparable platform-focused companies in the Stockholm ecosystem • Experience with identity federation and secure multi-tenant system design at scale • A track record of designing platform systems that other engineering teams depend on in production without requiring significant architectural revision • Demonstrated track record of delivering reliable platform infrastructure faster than peers scope it • 3–8 years of relevant experience
What We Offer Expect the most talented, rigorous, and driven colleagues you have worked with; people who lift each other up and hold each other to the highest standard. This company is driven by ideas and innovation, regardless of age, position, or background. The best ideas must win and the people behind them recognized and rewarded. A home for exceptional people and geniuses within their domain; those who have always known what they are capable of and have been waiting for the environment to prove it to the world, whilst first being seen and supported by their coworkers. Compensation includes an attractive salary and meaningful equity ownership for an early-stage startup.
