Descripción del empleo

• see end of post for application details*

Most "Junior Developer" roles are just ticket-pushing in disguise. We’re doing something different at Adaptrix.

We are building AI analytics that runs entirely on-premise. No cloud dependencies. No API calls. Total data sovereignty.

To do this, we’re solving problems that don’t have a StackOverflow answer yet. We’re looking for a Junior Developer who wants to skip the "pixel pushing" and go straight to the core :

LLM Orchestration: Fine-tuning and deploying models on local silicon.

Infrastructure: Managing Kubernetes clusters that don't rely on AWS magic.

Data Velocity: Building real-time pipelines for massive enterprise datasets.

Why join us? In most companies, juniors are "resources." At Adaptrix, you're an owner. We prioritize learning velocity over years of experience. If you can read the docs, bridge the gap, and care about the craft of engineering, you belong here.

THE ROLE

• Build features that ship to production
• Work across our Next.js frontend and Node.js backend
• Collaborate directly with founders and senior engineers
• 0-2 years experience (or exceptional student)
• Fast learner who takes initiative

WE OFFER

• Competitive compensation
• Fully remote (EU timezone)
• Optional co-working in Palma or Zurich (residents of Spain preferred)
• Possibility of equity participation for those who prove themselves

How to skip the line : We don’t care about your CV as much as your code. We’ve set up a technical challenge that mirrors the real-world problems we solve every day.
