Java Kotlin Agile Microservices

¿Que es Shifty?

Shifty es un marketplace que conecta a empresas con trabajadores operativos de forma ágil, flexible y bajo demanda. Comenzamos en el sector de la hostelería —cubriendo turnos de camareros, ayudantes de cocina y personal de eventos— pero nuestra ambición es mucho más amplia: estamos construyendo la infraestructura tecnológica que permita redefinir cómo se accede al trabajo blue collar en Europa. Queremos que cualquier persona pueda trabajar cuándo, dónde y cuanto quiera, sin papeleos ni fricciones.

Desde el lado técnico, Shifty automatiza el emparejamiento entre oferta y demanda de personal, integrando módulos de disponibilidad, geolocalización, sistema de reputación, logística y control horario. Las empresas pueden solicitar trabajadores en segundos desde una app, mientras que los trabajadores eligen turnos según sus preferencias y cobran en pocos días. Es un ecosistema en tiempo real, impulsado por datos y diseñado para escalar.

Shifty busca CTO para unirse al equipo y liderar la evolución de nuestra plataforma marketplace, definiendo la arquitectura de microservicios, potenciando el backend en Java y el frontend móvil en Kotlin Native, e incorporando soluciones de IA/ML que optimicen la asignación de turnos y eleven la calidad del servicio en el sector blue-collar en España.

Lo que harás

• Definir y ejecutar la visión tecnológica de la plataforma.
• Diseñar y mantener arquitecturas basadas en microservicios.
• Desarrollar en Java para el backend y Kotlin Native en el frontend móvil.
• Integrar soluciones de IA/ML para optimizar la asignación de turnos y mejorar la calidad del servicio.
• Implementar metodologías ágiles (Scrum/Kanban) para el desarrollo rápido de nuevas funcionalidades.
• Formar, liderar y mentorizar un equipo de desarrolladores de primer nivel.
  
  

Lo que buscamos

• 8–10 años de experiencia en desarrollo de sistemas escalables y arquitectura de software.
• Experiencia previa en roles de liderazgo técnico o CTO en startups de rápido crecimiento.
• Dominio de Java y arquitecturas de microservicios; Kotlin es un plus, pero estamos abiertos a que lo aprendas.
• Conocimientos sólidos de despliegue en la nube (AWS/GCP/Azure).
• Experiencia aplicando IA/ML en proyectos de matching o recomendación.
  
  

Qué ofrecemos

• Salario competitivo más paquete de stock options.
• Puesto presencial o híbrido (la persona debe residir en Madrid).
• Flexibilidad horaria y cultura de autonomía.
• Un reto de alto impacto: liderar la tecnología que transformará el acceso al trabajo blue-collar en España.
  
  

¡Impulsa el futuro del trabajo blue-collar en España con Shifty: únete a nosotros y lidera la próxima generación de talento!
