Every day, millions of people use SCRL to create and share content across social platforms. Behind the product is a small, profitable, and fully self-funded team based in Stockholm.

We’re looking for a Senior Backend Engineer to help shape that foundation. You’ll work on the systems powering user identity, content delivery, subscription management, and data synchronization across iOS, Android, and web, while helping define the architecture and engineering standards behind the platform long term. What you will do In this role you will own the backend that powers SCRL across iOS, Android, and our upcoming web platform. You will work both on the bigger architectural decisions with our CTO and Head of Data, and on the new features together with the frontend team during our sprints. Day to day, that means: Building and maintaining the APIs and services that deliver content to millions of users Designing systems that scale as we grow, without scaling our costs at the same rate Owning our PostgreSQL database and how we store and serve content Building scalable and cost-efficient systems for storing and delivering images and creative assets using AWS and S3 Making sure premium status stays in sync across iOS, Android, and web Implementing proper security and access control, and making sure we stay GDPR compliant as we start storing user generated content in the cloud What we are looking for Several years of experience building and operating backend systems in production Strong foundations in TypeScript and PostgreSQL Experience working with cloud infrastructure on AWS or GCP Experience building systems that have scaled in terms of users, traffic, or complexity Comfortable being a senior voice in discussions around architecture, tradeoffs, and long-term platform decisions What we offer We are a small, international team based by Slussen in central Stockholm.

What will you do? As a Senior iOS Engineer at Rebtel, you will be part of our Frontend team, helping modernize and evolve the Rebtel iOS app. The iOS team is two engineers, and you'd be the third.

You'll work in a small, empowered team where your technical decisions matter. This role is a mix of building new features, refactoring legacy code, collaborating cross-functionally, and shaping the future of our iOS platform.

Rebtel has been connecting people across borders for nearly 20 years. Today, we're profitable, growing, and at a pivotal moment in our journey.
