Linux Systems Developer

Why Barbara?

We’re not just another SaaS company. We operate at the intersection of Industrial Edge, AI, and Cybersecurity. With 9 years of stability and backing from industry leaders like Iberdrola and Caixa, we provide the brains behind Industry 4.0.

You’ll be building the foundational operating system that runs critical infrastructure—where stability isn’t a nice-to-have, it’s a requirement.

‍

The Role

We’re looking for a technically mature Linux Systems Developer to join our OS team in Madrid. You’ll design, build, and maintain the operating system at the core of our Edge platform.

This is a low-level, systems-focused role, close to the hardware, where reliability, security, and deep debugging are part of everyday work.

‍

What You’ll Do

• Design and evolve Linux-based systems for high-reliability industrial environments.
• Develop and maintain OS generation pipelines (image creation, build tooling, CI).
• Drive hardware integration at OS level: bootloaders, kernels, drivers, networking, and storage.
• Perform root-cause analysis, debugging, and performance tuning in embedded/edge systems.
• Contribute to our Docker-based deployment platform and Yocto build infrastructure.
• Collaborate with QA and platform teams to resolve complex incidents and deliver solid releases.

‍

What You’ll Bring (The Essentials)

• Linux mastery: Deep understanding of user-space and kernel-space (systemd, networking, filesystems).
• Embedded DNA: Hands-on experience with real hardware, toolchains, debugging, and build pipelines.
• Strong engineering practices: Git, clean code, and collaborative development workflows.
• Automation skills: Proficiency in Bash and/or Python (Go is a plus).
• Language: Professional English for documentation and cross-team collaboration.

‍

Nice to Have (Where you can shine)

• Hardware: ARM and x86 experience (Jetson, NXP i.MX8, BCM), including flashing, BSPs, drivers, and HW interfaces (GPIO, serial, etc.).
• Kernel: Kernel modules, system hardening, bootstrapping concepts (Secure Boot, initramfs, recovery).
• Build systems: Proven experience with Yocto and CI tooling (e.g. Jenkins).
• Containers: Production-grade Docker usage, container isolation, and security.
• Process: Comfortable working in Agile environments with tools like Jira and Bitbucket.

‍

Who you are (Soft Skills & Mindset)

• Autonomous: You take ownership of complex problems and drive them to completion.
• Clear Communicator: You can translate complex "kernel-speak" into actionable insights for other teams.
• Methodical: You enjoy the "puzzle" of debugging and root-cause analysis.
• Geek at Heart: You have a passion for tinkering and are driven by a genuine love for the craft.

‍

What’s in it for you

• Impact: Work on technology that interacts with the real world.
• Tools: Top-tier equipment (tell us what you need to be productive).
• Hybrid Work: 2–3 days remote, the rest in our Madrid office.
• Flexible Benefits: Cobee for meals, transport, and training.
• Wellness: Wellhub subscription for gyms and mental health.
• Social: Epic BBQs on our terrace with a great team.
