AI Solutions Architect / AI Infrastructure Engineer – Barcelona / Remote (Hybrid)

Are you ready to work at the intersection of Artificial Intelligence, cloud architecture, and large-scale production systems?

We are currently partnering with a fast-scaling European tech startup with offices in Barcelona in the search for an AI Solutions Architect / AI Infrastructure Engineer. This is a rare opportunity to join a high-growth environment where AI is not just a feature — it is a core part of the product and platform strategy.

This role is designed for highly experienced engineers who can bridge the gap between AI systems, cloud infrastructure, and scalable production architecture.

The position is hybrid in Barcelona, with strong flexibility for remote work depending on experience and profile.

The Opportunity

This is one of the most in-demand and hardest-to-fill AI roles in today’s European tech market.

You will be responsible for designing and scaling AI-ready infrastructure and production environments, ensuring that machine learning and generative AI systems can run reliably, securely, and at scale across cloud platforms.

You will act as a key technical bridge between:

AI/ML engineering teams
Data engineering
Cloud & platform engineering
Product & architecture leadership

This is not a research role — it is a production-focused, architecture-driven AI engineering position.

What You Will Be Doing

Design and build scalable AI infrastructure and cloud-native architectures.
Lead the deployment of AI/ML models into production environments.
Define and optimize end-to-end ML pipelines and LLM-based systems.
Architect distributed systems for AI workloads and real-time data processing.
Work on GPU-based infrastructure for training and inference workloads.
Implement and improve MLOps and LLMOps frameworks.
Ensure performance, scalability, reliability, and cost efficiency of AI systems.
Collaborate with data engineers, ML engineers, and DevOps teams.
Drive best practices in AI security, governance, and compliance.
Support multi-cloud and hybrid cloud strategies when required.

Tech Stack & Environment (2026)

The company operates in a modern, cloud-native AI ecosystem including:

AWS / Azure (multi-cloud environment)
Kubernetes & container orchestration
Terraform (Infrastructure as Code)
GPU infrastructure (NVIDIA-based systems, cloud GPU clusters)
ML pipelines (Kubeflow, Airflow, or similar)
LLMOps frameworks (LangChain, LlamaIndex, etc.)
Vector databases (Pinecone, Weaviate, FAISS)
Distributed systems architecture
Data engineering tools (Spark, Kafka, dbt)
CI/CD for ML systems
Observability & monitoring (Datadog, Prometheus, Grafana)
Security, IAM, and cloud governance

Candidate Profile

5–10+ years of experience in Cloud Engineering, Data Engineering, ML Engineering, or AI Infrastructure roles.
Strong background in cloud architecture (AWS or Azure essential).
Proven experience building and scaling production AI or ML systems.
Deep understanding of distributed systems and scalable architectures.
Hands-on experience with Kubernetes, Terraform, and CI/CD pipelines.
Experience with LLM-based systems and modern AI frameworks is highly valued.
Strong focus on reliability, performance, and security at scale.
Ability to work in fast-moving, product-driven environments.

Language Requirements

English: Native or bilingual level (mandatory) for daily communication in an international environment.
Additional European languages (French, German, Dutch, Italian, Nordic languages) will be considered a strong plus due to the company’s expansion strategy across Europe.

What’s On Offer

Hybrid working model based in Barcelona, with flexible remote options.
Opportunity to join a fast-scaling European AI-driven tech company.
Work on cutting-edge AI infrastructure and production-scale systems.
High level of ownership and technical influence on architecture decisions.
International, engineering-led culture with strong technical autonomy.
Competitive compensation package aligned with senior AI infrastructure profiles.
Long-term growth opportunities in one of the most strategic areas of tech: AI systems at scale.

As a recruitment partner specialized in AI recruitment, cloud engineering hiring, and international tech talent acquisition in Spain, we work with high-growth startups and scale-ups building next-generation AI and data-driven platforms.

If you are looking to take ownership of complex AI systems, architecture challenges, and production-scale infrastructure, this could be your next step.

We would be happy to speak with you confidentially.
