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.

- 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

- 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

- 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:
