Are you passionate about Video on Demand? Are you a Mobile engineer who is curious about — or already working with — Kotlin Multiplatform? Rakuten TV is looking for a Mobile Engineer with strong iOS roots and a multiplatform mindset to join our growing engineering team in Barcelona. Work with a team of wildly talented and highly motivated coworkers in the fast-growing industry of Video on Demand in one the most exciting cities in Europe, Barcelona.
You will contribute to mobile products at different stages of their lifecycle — from maintaining and evolving a mature, high-quality native iOS application used by millions of customers, to building new multiplatform experiences using Kotlin Multiplatform and Compose Multiplatform.
This role requires you to be comfortable in both worlds: writing clean, idiomatic Swift for native iOS and contributing to a shared KMM codebase where business logic, networking, and data layers are written in Kotlin and run across platforms.
You will be part of an end-to-end product team alongside developers, QA engineers, designers, and product owners — from concept to deployment and maintenance.
