Senior Software Engineer, iOS

Join us in building a world-class creative platform used by millions of people.

Our product, SCRL, is a powerful photo and video editing platform loved by millions of creators worldwide. We're looking for a Senior iOS Engineer to help build what comes next.

This isn't a typical iOS role. SCRL is a tool people use to create, not just consume. That means you'll be working on things most apps never touch: real-time image and video manipulation, complex multi-touch interactions, advanced layout systems, and performance-sensitive rendering pipelines.

You'll work across the full depth of the app, from pixel-level rendering to fluid, responsive UI that feels effortless to use. The problems are hard, the users are demanding, and the bar for quality is high.

• Build and evolve SCRL's editing engine, working on image processing, video rendering, and real-time visual effects.
• Design and implement complex interaction models: multi-touch gestures, precise object manipulation, drag, resize, snap, and transform.
• Solve hard problems in coordinate geometry, layout systems, and state management.
• Push performance to its limits, optimising rendering, memory usage, and responsiveness across a wide range of devices.

• Own features end to end, from planning through to delivery.
• Write code that is fast, correct, and maintainable.
• Sweat the details that make the difference between a good tool and a great one.
• Work closely with design to get interactions, animations, and transitions feeling exactly right.

• Contribute to architecture decisions and help shape the technical direction of the iOS codebase.
• Participate in code reviews, planning sessions, and technical discussions.
• Share knowledge and help raise the bar across the engineering team.
• Stay sharp on the latest in the iOS ecosystem and bring ideas back to the team.

• Extensive experience in iOS development and Swift.
• Strong computer science fundamentals: data structures, algorithms, and an intuition for performance.
• Experience building complex, interactive, gesture-driven interfaces.
• A deep understanding of UIKit, Core Animation, and the iOS rendering pipeline.
• The ability to reason about performance at a low level: frame rates, memory, GPU vs CPU tradeoffs.

• Experience with image processing, video rendering, or real-time graphics on iOS.
• Familiarity with Metal, Core Image, AVFoundation, or similar frameworks.
• Background in creative tools, design software, or editor-style applications.
• Experience working on consumer apps with large user bases.
• Interest in geometry, math, or computational problem solving.

• The chance to work on genuinely hard, interesting problems every day.
• A product that millions of people use to create, not just another feed or dashboard.
• Real ownership and direct impact in a small, focused team.
• Great colleagues and office in central Stockholm.
• Competitive compensation and opportunities for professional development.
