More about the role

Senior iOS Developers are responsible for the development, unit testing, and maintenance of new and existing features on our iOS App. They guarantee that the features meet the functional and non-functional requirements, and quality standards required by New Look.

Senior iOS Developers monitor the quality of the released features/changes by regularly reviewing crash reports, performance analytics for live environments, and triaging bugs with the testing team.

Senior iOS Developers work closely with other developers on the Mobile Team, with other domains within New Look, with third-party suppliers, on-site or offshore, and with guidance from the Engineering Lead to deliver the best, and most cost-effective solution for our customers on the iOS App.

Senior iOS Developers are responsible –alongside the Engineering Lead, Test & Automation Lead, and DevOps– to identify opportunities for automation to speed up the development, testing, and release cycle of the iOS App within a CI/CD pipeline.

Senior iOS Developers are accountable for the quality of the application, and features released, and that the quality is maintained or improved with each release by avoiding the introduction of regression bugs, and peer reviewing the code to be delivered.
