Job description

World-Class Technology Company in Edinburgh are looking for a skilled Senior Software Engineer ( iOS ) to join one of their core product engineering squads. Hybrid working, cutting-edge tech, and a brilliant culture on offer.

They've been steadily growing for several years and have established themselves as one of the key players within their field - they're continuing to scale multiple squads and invest heavily in their mobile and platform engineering capability, so it's a really exciting time to join.

You'd be joining one of their core teams, working on foundational engineering and helping to improve the underlying frameworks, tooling, and performance that enable the company to deliver a world‑class customer experience. This team has a big focus this year, with several major initiatives planned around performance optimisation, scalability, and mobile innovation - so there's plenty of interesting and challenging work ahead.

You'll be working closely with both React Native and native iOS codebases, building and optimising select iOS components while enhancing the overall mobile platform performance. There's a real opportunity here to make an impact on platform quality, developer experience, and overall app performance.

You'll be regularly involved in design discussions and technical decisions, where you'll have the freedom to suggest solutions and help contribute to the team's wider technical vision. As a Senior Engineer, you'll also play an active role in mentoring others, sharing best practices, and helping strengthen the foundations of the mobile platform.

You'll ideally have good experience with the following;

• Delivering production React Native applications
• iOS development with Swift
• Mobile performance profiling and optimisation
• Advocate for best practices, testing, and CI CD pipelines

The following experience is highly desirable;

• Experience improving app scalability and performance
• Mentoring and supporting other Engineers

They've got custom-built offices in central Edinburgh, complete with games consoles, pool tables, and even their own gym - where they support hybrid working (ideally a couple times a week in office).

In return, they're offering a competitive salary (happy to discuss prior to application) and an excellent benefits package - including multiple bonuses and uncapped holidays.
