# Full Stack Junior-Mid (Next.js + TypeScript)

- **Company:** Biotasmart
- **Location:** Valencia, Spain
- **Contract:** Permanent contract
- **Skills:** Application Programming Interfaces (APIs), Software as a Service, Databases, Liquibase, Next.js, TypeScript, Network Routers, Tailwind, Spring-boot, Backend, Kotlin, Crud
- **Published:** August 20, 2026
- **Apply:** https://www.studentjob.es/ofertas/8257280-full-stack-junior-mid-next-js-typescript/solicitudes/nueva

## About the Role

No hace falta que llegues sabiendo Kotlin ni Spring Boot, lo valoramos como plus, no como requisito. Lo que sí necesitas es la base para poder aprenderlo rápido trabajando codo a codo con el CTO., * Features de frontend sobre tickets ya definidos, con criterios de aceptación claros

 * Alguna tarea de backend (CRUD, un caso de uso nuevo, un fix) según vayas ganando contexto
 * QA estructurado de lo que entregas: reproducir, validar, comprobar que no rompiste nada
 * Trabajar con Claude Code como herramienta diaria, sobre código propio y ajeno.

## Description

El grueso de tu trabajo es frontend, la web de profesionales y pacientes está en Next.js 16 (App Router) + TypeScript + Tailwind. Vas a construir pantallas reales, no maquetas ni prototipos.

Con menos peso, pero presente desde el primer mes, tocarás backend, el API está en Kotlin + Spring Boot y de ahí saldrán tareas de complejidad creciente (un endpoint nuevo, una migración de base de datos con Liquibase, una regla de negocio en la capa de dominio).
