Front-end utvecklare - Lediga jobb

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. We're moving off legacy Objective-C toward a modern Swift, SwiftUI, and Combine stack, and shifting the architecture from VIPER to MVVM-C, all while continuously shipping product features to a global user base. 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.

Areas of ownership:

• Drive the modernization from legacy Objective-C to a modern Swift + SwiftUI stack

• Refactor code that slows us down and proactively pay down tech debt

• Build and modernize iOS features using Swift, SwiftUI, and Combine

• Contribute to architecture decisions (VIPER to MVVM-C transition, Combine, platform improvements)

• Collaborate closely with Android, Web, Product, Design to ship the right solutions

• Ship to the App Store and monitor what happens after release

• Improve tooling, testing practices, and CI/CD where needed

• Maintain and improve the overall health of the iOS platform

Requirements:

• 5+ years building iOS apps

• Proficient in Swift, SwiftUI, and Combine

• Comfortable maintaining and modernizing legacy Objective-C

• Solid grasp of iOS architecture patterns (MVVM-C, VIPER)

• Shipped production iOS apps to the App Store, including post-release monitoring

• Experience with REST and/or GraphQL, with solid error handling and async patterns

• Can work independently and ship without constant oversight

• Write unit tests, cover edge cases, and give code reviews that favor simple solutions

• Work effectively with AI coding tools

• Good English (we write and speak it all day)

Nice to have:

• Worked on large, mature products

• Mobile CI/CD, testing, and DevOps experience

• Audio or telecommunications experience

Why Rebtel?

Rebtel has been connecting people across borders for nearly 20 years. Today, we're profitable, growing, and at a pivotal moment in our journey. We make it cheap and easy for migrants to call and send money home. Millions of people move countries every year, and staying connected with family shouldn't cost a fortune. That's the problem we work on, from a small, international team based in Stockholm where speed and ownership matter more than process.

Benefits

• Pension Plan

• Health Checkups, Influenza shots, and Private Medical Insurance

• Dental Insurance

• Occupational insurance

• Wellness allowance (5,000 SEK)

• Discount on gym memberships

• Bonus program

• Extra parental pay

• 30 days annual vacation

• Monday breakfasts

• Relocation Support

Equal Opportunity

We are Rebtel. We come from all around the world to create products for anyone who has crossed a border. We believe in equal opportunity and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.

• A strong understanding of clean code, frontend performance and optimization

• Experience integrating AI-assisted workflows into frontend development, such as code review, test generation or automation

• Experience creating and maintaining executable specifications or living documentation alongside evolving code

• Familiarity with Model Context Protocol, MCP, and connecting AI tooling with internal systems

• Experience using AI-assisted code review as part of a development workflow

Nice to have:

• Experience with Node.js, other programming languages or full-stack development

• Experience with Redux, React-Redux or redux-saga

• Experience with styled-components or similar styling solutions

• Experience with Jest or other frontend testing frameworks

• Experience working with multimedia such as video, audio or image optimization

• Experience developing interfaces for networking, mobile or IoT products

• Experience with visualization libraries for topology maps, hierarchical graphs or interactive layouts

• Experience implementing interactive UI functionality such as zooming, panning, snapping or node-link editing
