About the role

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

Design and operate cloud infrastructure for large-scale consumer platforms with a strong focus on compute, networking, GPU resource management, and cost efficiency as a first-class engineering priority

Build Kubernetes-based orchestration systems with deep understanding of resource scheduling, isolation boundaries, failure propagation, and operational reliability

Build high-performance ML model serving infrastructure supporting concurrent model versions, canary and shadow deployments, and low-latency inference delivery within the performance and reliability constraints of a live consumer product

Build CI/CD pipelines that give the team the deployment confidence and velocity of a dedicated platform engineering function

Design data architecture with built-in classification, retention policies, access controls, and audit logging from day one

Build comprehensive observability infrastructure including distributed tracing, model performance monitoring, cost tracking, and intelligent alerting for full production visibility

Minimum Qualifications

MSc in Computer Science, Software Engineering, or a directly related field from KTH, Chalmers, or an institution of equivalent standing - or equivalent demonstrated production experience in lieu of formal qualification

2 or more years of experience originating and operating production infrastructure at meaningful scale; has designed systems that real products depend on, not maintained existing ones

Kubernetes expertise below the configuration layer; real understanding of scheduler behavior, runtime characteristics, and resource contention

Experience operating ML workloads in production; model versioning, inference scaling, and GPU resource management

Infrastructure-as-code practice applied comprehensively and without exception

Preferred Qualifications

Experience with GDPR obligations applied at the infrastructure and data architecture level

Background from Spotify infrastructure, Ericsson cloud, King platform engineering, or Einride

Demonstrated track record of provisioning production-grade infrastructure at a pace that sets a new reference point for teams around you

2–7 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.
