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 is still stuck in spreadsheets and legacy software.
Your Role
You'll be a core member of our product engineering team, designing and building the infrastructure that powers Valeria. From architecting scalable APIs to integrating with Spanish government systems and building AI‑powered features, your work will directly impact how thousands of employees get hired, paid, and managed.
- Design and build scalable backend services using Python (Flask), with clean architecture patterns and modern Python practices
- Architect cloud‑native solutions on Azure with focus on reliability, performance, and cost‑efficiency




- Build and integrate AI capabilities into the product: document processing, contract generation, compliance automation, and intelligent workflow optimization
- Develop complex integrations with external systems: Spanish Social Security (Seguridad Social), SEPE, payroll providers, e‑signature APIs—handling real‑world edge cases and compliance requirements
- Implement event‑driven architectures and async processing for high‑volume operations (batch payroll for thousands of employees)
- Optimize database performance: design PostgreSQL schemas, write efficient queries, implement caching strategies with Redis
- Contribute to frontend when needed (React/TypeScript stack)—we value full‑stack mindset
- Establish engineering best practices: CI/CD pipelines, comprehensive testing (pytest, integration tests), code reviews, monitoring and observability
- Own features end‑to‑end: from technical design and architecture discussions to deployment
