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.

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
