Linux Engineer – Shape the Future with Code

Linux Engineer – Help Build the First True AI Operating System

KerrOS – Where code becomes intelligence, and infrastructure learns to think.

At KerrOS, we’re not building just another Linux distro or fancy shell. We’re building a self-learning, AI-driven operating system—a foundation where specialized AI agents collaborate, create tools, automate workflows, and evolve with you. Think of it as a living system that understands your infrastructure, respects your stack, and makes your business run ten times more efficiently.

This isn’t just about automating tasks—it’s about transforming how work gets done.

We’re looking for a Linux Engineer who lives and breathes systems. Someone who’s passionate about simplicity, open source, and hacking smarter—not harder. Someone who knows the command line is still the most powerful UI ever built, and that beneath every flashy tool is a well-behaved process.

🧠 About You – The Linux Purist with AI Curiosity

Curious Explorer: You’ve probably installed more distros than you can remember. You know why Alpine exists, and you’ve got Opinions™ about init systems. You’re deeply curious and love dissecting how things work at the OS level.

Prototype Builder: Your GitHub is a museum of cool side projects—some rough, some polished, all driven by curiosity. You build because it’s fun, and you learn by getting your hands dirty.

Simplicity Seeker: You believe in the Unix philosophy and admire tools that do one thing well. When you spot complexity, your instinct is to refactor it away.

AI-Powered Engineer: You’ve embraced AI tools not as gimmicks, but as powerful collaborators. You move faster, explore deeper, and think bigger because you know how to prompt, test, and integrate AI into your workflow.

Initiative Taker: You don’t wait for specs—you define them. You think in systems and build with intent. You prefer launching imperfect solutions over endlessly planning perfect ones.

Mission-Driven Teammate: You want to work on something that matters—with people who care. You’ve got a passion for elegant systems and a distaste for bureaucracy.

🧬 Our Mission

At KerrOS, we’re building the world’s first true AI Operating System—a platform where:

  • AI agents build their own tools, connectors, and flows
  • Complex business logic is orchestrated automatically
  • The system learns from how you work, not the other way around
  • Everything runs securely on your own infrastructure, respecting your stack
  • Human expertise is preserved and extended—not replaced

We’re creating an OS that starts as an empty canvas, learns from your environment, and evolves into a system that fits you like a glove.

🛠 Your Role – Let’s Build Smarter Infrastructure Together

System Architecture: Help shape and evolve the core infrastructure of KerrOS—from process orchestration to service management to secure agent execution.

Service Creation: Build new services and foundational components that will power our AI agents and automation layer.

Low-Level Wizardry: Work close to the metal, from kernel configs to network tuning, helping ensure the OS layer is fast, secure, and rock-solid.

Tooling and Automation: Help us automate everything—because the best shell script is the one that writes itself (or gets written by AI).

AI-Native Integration: Collaborate with our AI team to ensure the system can be introspected, monitored, and controlled by intelligent agents.

🌍 What We Offer – Why Join Us?

  • Fully remote – Work from anywhere in Sweden, with full autonomy
  • No meetings culture – We believe in deep work, async comms, and smart people not needing constant oversight
  • Elite team – Work with developers who care deeply about quality, and are at the top of their game
  • Open source mindset – Build with, and for, the community. We don’t gatekeep knowledge—we share it
  • Work with AI, not around it – Be part of a system that puts AI where it belongs: everywhere

✨ Why This Isn’t “Just Another Job”

Because you’re not just maintaining systems—you’re inventing the next layer of computing. You’re helping build a platform that learns and adapts to its environment. You’re joining a team that codes because it’s fun and fulfilling. You’re entering a space where one developer with AI can do what used to take a whole team.

If that excites you, we’re probably already aligned.
