About Valeria
Valeria is building the future of HR and payroll in Spain. We're an AI-native platform that automates contracts, payroll, and compliance for companies with high employee turnover (hospitality, delivery, events, agriculture). We're rethinking how an entire industry works—moving from manual, error-prone processes to intelligent automation.
We're a fast-growing startup backed by top investors, disrupting a €5B+ industry that's still stuck in spreadsheets and legacy software.

Valeria is an AI-native HR and payroll platform built for the way modern companies actually work. We automate the complex, compliance-heavy work that slows People teams down — so they can focus on what matters: their people.

What You'll Work On

As our AI Engineer Intern, you won't be watching from the sidelines — you'll be building real features that go into production and directly shape how HR teams experience AI.

AI & Document Intelligence

Build and improve LLM-powered pipelines for HR document processing (contracts, payslips, policies)
Work on extraction, classification, and structuring of unstructured HR data
Experiment with prompt engineering and RAG approaches to improve accuracy and reliability

Backend & API Development

Contribute to our Python (Flask) backend using clean architecture principles
Build and maintain RESTful APIs and async job processing pipelines on Azure
Work with PostgreSQL — designing schemas, writing queries, optimizing performance

Frontend & Product

Contribute to our React / Next.js / TypeScript frontend — connecting AI features to user-facing experiences
Collaborate closely with the product team to turn user needs into working features

Infrastructure & Observability

Work within our Azure cloud environment and CI/CD pipelines via GitHub Actions
Use Azure Monitor and Application Insights to understand how your features perform in production

Tech Stack

AI/ML — LLM integrations (OpenAI, Anthropic), Document processing, vector search

Backend — Python, Flask, clean architecture, async processing, webhooks

Database — PostgreSQL Frontend — React, Next.js, TypeScript

Cloud — Azure, GitHub Actions, Azure Monitor, Application Insights

What We're Looking For

Must-have

Currently in your final year of a CS, AI, Data Science, or related degree — or recently graduated / finishing a Master's
Solid Python fundamentals and genuine comfort working in a codebase you didn't write
Hands-on experience or strong academic knowledge of LLMs, prompt engineering, or AI pipelines
Ability to work independently: you don't wait to be told what to do next
Good written English — our team communicates async and in English

The X-Factor

We're a small team — every person here has a real impact. Beyond skills, we look for:

Genuine curiosity about AI
Product intuition — you care about the user, not just the tech
Low ego, high ownership — you're comfortable saying "I don't know" and figuring it out
Startup mindset — you thrive with autonomy and are energized by ambiguity

What We Offer

Paid internship
Free lunch when you're at the office (thanks to Nora & Kombo)
Real ownership from day one — you'll ship features that real users interact with
Hybrid flexibility — based in Barcelona, async-friendly setup
Direct mentorship — work alongside senior engineers and the founding team
Front-row seat to AI in production — see your work go live and iterate on real feedback

The Process

Intro call (30 min) — we get to know each other and answer your questions

Team interview — meet the people you'd be working with day to day
