Software Engineer, iOS SDK

London, England, United Kingdom · Engineering


Permutive is looking for an iOS engineer to help connect our real-time data platform to the rest of the world.

Our iOS SDK is responsible for tracking billions of events every day, syncing with our cloud infrastructure, and reacting to events in real-time. This is not a typical SDK: it is highly complex, involving the sequencing of asynchronous code and careful state management, and runs at scale on millions of devices every day. This presents a number of interesting engineering challenges, and for this reason, we believe a computer science degree and some experience in backend engineering is essential for this role. We'll be happy to discuss this in more detail if you come in for interview.

The SDK is written in Objective-C, which can then be used with Swift and Objective-C by our customers as part of their iOS apps. We are looking for an engineer to take full ownership of this important part of our product, maintaining the roadmap and planning new features from inception to deployment.

An ideal fit is a candidate with a technical, computer science background and some commercial experience. You should be keen to join a fast-growing startup in a role where you'll have ownership of a core part of the platform.
