Middle Full Stack Developer (Generative AI)

Location: Spain (100% Remote)

Type: Full-time

Compensation: 35K-45K

About the Role

We’re looking for a Middle Full-Stack Developer to build and deploy cloud applications for Generative AI within the Microsoft ecosystem. The role leans toward backend (Python or .NET on Azure), where most of the work happens, with frontend work in React/Next.js when a feature needs it end-to-end. We work across both languages, so being comfortable with either is essential, and experience with both is a real plus.

You’ll own the full lifecycle of cloud services (development, deployment, monitoring, troubleshooting, and maintenance) with a strong focus on practical AI solutions built around LLMs, RAG, and agent-based architectures.

This is a fully remote position based in Spain , ideal for someone who enjoys innovation, ownership, and collaboration.

Cloud: Microsoft Azure
AI / GenAI: LLMs, RAG, agentic frameworks
Frontend: React, https://jobeax.com/link/Z30sZYC3jcRenVso

Observability: Logging, monitoring, tracing
Infrastructure as Code: Pulumi (or equivalent: Terraform, Bicep)

Key Responsibilities

Design, develop, and maintain production-grade full-stack applications and APIs powered by Generative AI.
Build scalable backend and frontend solutions in Azure.
Integrate Generative AI technologies (prompt engineering, RAG, Agents, MCPs...).
Collaborate with technical and business teams to define and implement solutions.
Ensure code quality, performance, and system reliability.
Stay updated on emerging technologies and AI trends.

Requirements

3+ years of professional software development experience, ideally building cloud applications.
Strong backend experience with Python and .NET .
Practical experience with Microsoft Azure .
Experience with Azure DevOps, Git and CI/CD pipelines .
Experience building applications that integrate LLMs, RAG or AI agents .
Working knowledge of Infrastructure as Code (Pulumi, Terraform, Bicep or similar).
Comfortable contributing to a React/Next.js frontend when needed.
Understanding of observability concepts (logging, monitoring, tracing, troubleshooting).
Professional working proficiency in English .
Must reside in Spain and have legal authorization to work in Spain.
Strong communication, organization and stakeholder management skills.
Experience working in Agile teams using Azure DevOps, with a strong foundation in Agile principles and a mindset shaped by practical experience in real delivery environments.

Nice to Have

Experience with both Python and .NET .
Vector databases or vector search.
Interest in data : Databricks (Unity Catalog, Genie) or Azure Data Platform (Fabric, Data Factory, Data Lake Gen2).
Experience in monitoring or evaluating GenAI applications in production .
Azure or Databricks certifications.

What We Offer

Permanent employee contract (Spanish payroll).
100% remote within Spain, flexible working environment.
30 days of paid vacation.
3 team-building events per year
Dedicated budget for training and certifications.
Hands-on work with Generative AI, RAG and agent-based architectures.
Ownership across the full lifecycle of cloud-based AI applications.
