Job description

We’re looking for a Senior Backend Engineer to join an AI team working on a Secure GPT platform (an internal ChatGPT-like solution) used across a global environment.

The focus of the role is to build real AI features in production, making them scalable, secure, and actually useful for the business.

What you’ll be doing

Building and improving backend features (mainly Node.js / TypeScript)
Working on GenAI use cases like:
- document understanding
- translation
- agent-based workflows
- APIs and automation
Owning your work end-to-end (from design to production and monitoring)
Defining and tracking how features perform (KPIs, usage, etc.)
Collaborating with product and tech teams in an international setup
Continuously improving how things are built and scaled

️ Tech environment

Backend: Node.js, TypeScript
Frontend: React / Next.js (light involvement)
Cloud: Azure (App Services, Cosmos DB, monitoring)
CI/CD and DevOps practices
GenAI: OpenAI, Azure AI, RAG, agents, prompt engineering

Job requirements

✅ What we’re looking f

Solid backend experience (ideally 5+ years)
Strong Node.js / API development background
Hands-on experience with AI in real use cases (LLMs, RAG, agents…)
Comfortable working in cloud environments (Azure is a plus)
Someone who takes ownership and can work end-to-end
Practical, problem-solving mindset
Comfortable working in English

➕ Nice to have

Terraform / Bicep
Observability / monitoring experience
Exposure to regulated environments or security topics

Why it’s interesting

You’ll be working on AI that is already in production, not just experiments
Real ownership of what you build
Modern stack + interesting technical challenges
Strong mix of backend + AI

Hybrid

Barcelona, Catalunya [Cataluña], Spain
