iOS Engineer

At Thread we’ve set out to rethink clothes shopping for the digital age. By combining talented stylists, powerful AI, and a marketplace with one of the largest fashion ranges in the world we’ve created a truly unique online platform that gives everyone in the world their own personal clothes store. 

A store where everything suits you, fits you and works with what you already own. A store that gives you confidence in the choices you are making, inspires you to step out of your comfort zone and helps you feel your best every time they get dressed. 

Over 1 million people and counting use Thread. We’ve recently launched womenswear which is growing faster than our menswear business and, for 25% of our customers, we’ve become the only way they shop. 

There’s a $10bn+ opportunity globally to build the Spotify of retail, and we’re leading the way.

The Role

We’re looking for a passionate iOS engineer to help us evolve Thread’s app into THE clothing app on the App Store. You’ll be the first hire in a brand new iOS team and be responsible for shaping our iOS culture and technical decisions as we grow the team further this year and beyond. We’ve just released a new version of our app that is showing great traction. We see the app as critical to Thread’s future and we’re looking for somebody to own mobile engineering and help fulfill the vision of our app.

Our brand new Swift codebase is highly modularised, designed to scale and built directly on top of the latest iOS frameworks, including SwiftUI and Swift Packages. We have a clean and tidy App Delegate class, we have continuous integration for builds and all App Store uploads are automated in CI. We make use of code generation for all of our API types and calls, as well as for our translated strings and asset catalog references. We only support iOS 14 and above and are only committed to support the current and previous iOS releases. We also have zero build warnings!

We want to raise the bar for online shopping apps by delivering breakthrough, AI-assisted personal styling in the shape of a world-class iOS app with outstanding user experience. We are at the early stage of our iOS team, with the vision of gradually scaling towards a model in which iOS expertise is ubiquitous in our product teams and is involved in designing every aspect of the Thread product whilst also maintaining its unique identity.

At Thread we offer hybrid working, and flexible working hours. We benchmark twice a year, against similar size start-ups, to ensure we are paying in the top percentile.
