Our engineering team architects, develops, and tests our products. As a Full-Stack Engineer, your mission is to build features end to end, from the browser to the database, on a platform that serves millions of views every month.

As a member of an international, cross-functional Product Experience Team (PXT), you work closely with your Product Manager to architect, implement, and ship concepts and upcoming changes. You will write automated unit, integration, and end-to-end tests. You will take part in cross-team initiatives: architectural changes, refactoring, and best practices.

- Experience with a modern web framework like Symfony, Laravel, Next.js, or React
- Hands-on experience using AI tools in your everyday engineering work
- Experience with automated testing on the unit, functional, and/or acceptance level
- An interest in big datasets in relational databases, search indexes, or key-value stores
- Excellent English, written and spoken, as it is our company language
- Strong communication skills and a self-motivator, used to working with multiple teams across disciplines in a fully remote setting
### What we value

- Bettering our skills, teaching each other and learning ways to build better software
- User testing, experimentation, automated testing, and continuous integration to gain meaningful feedback
- Fostering collaboration and cooperativeness
Technologies we use: PHP, Symfony, MariaDB, Solr, RabbitMQ, Redis, Memcached, Behat, PHPUnit, TypeScript, Next.js, React, TanStack Query, MUI

Where we work: We work fully remote and are looking for people based in Spain who already have the right to work there. Twice a year the whole team meets in person, travel and accommodation covered.
