Funciones del cargo
Buscamos un/a Backend & Infrastructure Engineer para liderar tres áreas críticas de la plataforma: la API pública, las integraciones con CRMs y la infraestructura cloud. Será responsable de la API REST usada por desarrolladores y partners para generar vídeos de forma programática, diseñando nuevos endpoints, gestionando autenticación, rate limiting, webhooks, monitorización y documentación, así como mejorando la experiencia de desarrollador.
También desarrollará integraciones con CRMs inmobiliarios y otras plataformas externas, creando pipelines de sincronización de datos, arquitecturas orientadas a eventos, gestión de OAuth y claves API, y coordinándose con el equipo de negocio para priorizar alianzas.
En infraestructura, gestionará y optimizará entornos en Google Cloud y AWS, garantizando fiabilidad, escalabilidad y eficiencia de costes. Esto incluye servicios como Cloud Run, Pub/Sub, S3 o Lambda, además de CI/CD, despliegues automatizados, monitorización, alertas y seguridad en todos los entornos. Administrará contenedores Docker, configuraciones y variables de entorno.
No es un rol de soporte: diseñará sistemas, tomará decisiones arquitectónicas y desarrollará funcionalidades end-to-end, trabajando directamente con el CTO y teniendo un impacto clave en la evolución técnica del producto.

Requerimientos del cargo
What We Are Looking For
Must Have
3+ years of professional experience building and operating backend services
Strong TypeScript / Node.js skills in production environments
Hands-on experience with Google Cloud Platform (Cloud Run, Cloud Tasks, or similar)

Experience with PostgreSQL (or similar relational databases) in production
Familiarity with Docker and container-based deployments

Ability to work autonomously, make decisions, and communicate clearly

Ship the right solution for today, not an over-engineered abstraction for hypothetical tomorrow.
Clear communication.

Curiosity about the product.
Understand why we build what we build, not just how.

Nice to Have
Experience with AWS services (S3, Lambda)

Familiarity with observability tools (Sentry, Grafana, Prometheus)
Experience with OpenAPI specifications and API documentation tools
