Q Innovations; Stockholms kommun; On-site; SEK 700,000 - 1,100,000; Full time

Job summary

Q Innovations in Stockholm is seeking a Platform Engineer to design and operate cloud infrastructure for large-scale consumer platforms, focusing on compute, networking, GPU management, and cost efficiency.

You will build Kubernetes-based orchestration systems, ML model serving infrastructure with canary/shadow deployments, and low-latency inference within production constraints. Apply CI/CD, data governance, and full observability to ensure reliability.

Qualifications

• Master's degree in Computer Science, Software Engineering, or equivalent; or proven production experience.
• 2+ years of experience operating production infrastructure at meaningful scale.
• Kubernetes expertise at scheduler/runtime level, not just config.
• Experience operating ML workloads in production (model versioning, inference scaling, GPU management).
• Infra-as-code practices applied across the stack.

Responsibilities

• Design and operate cloud infrastructure for large-scale platforms, focusing on compute, networking, GPU management, and cost efficiency.
• Build Kubernetes-based orchestration systems with robust scheduling, isolation, and reliability.
• Develop ML model serving infrastructure with multi-version support and low-latency inference.
• Create CI/CD pipelines to enable fast, confident deployments.
• Design data architectures with access controls and audit logging from day one.
• Build observability tooling for distributed tracing, monitoring, and alerting in production.

Job description

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.

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.

Equal Opportunity

We are an equal opportunity employer committed to building an inclusive, high‑performance culture where everyone can do their best work and reach their full potential. We welcome applicants of all backgrounds and do not discriminate on the basis of race, color, religion, national origin, gender, gender identity or expression, sexual orientation, age, disability, or any other characteristic protected by applicable law.

Application

To apply, send your CV/resume with direct references, GitHub profile, LinkedIn profile, and a brief note on how and why you would like to contribute to our mission to [e-mail]. Upon initial acceptance, an in‑person interview will follow shortly in Stockholm, Sweden.

Please note that all applications and interviews are conducted in English. Fluency in written and spoken English is a requirement for all roles.

All applications are treated with strict confidentiality.
