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.

About The Role

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.

What you will do

Core Product Engineering

• 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.

Quality & Craft

• 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.

Collaboration & Growth

• 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.

You should have

• 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.

Strong signals

• 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.

What we offer

• 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.

We’re a growing team based in central Stockholm, working closely across disciplines to build products people love. We care deeply about craft, collaboration and creating a place where everyone can learn and grow.
