Consider joining a small team writing the software which provides mail services to iCloud customers. We are looking for an extremely capable engineer who has a strong background in building high-performance, scalable and extensible systems. In this highly visible position, the successful candidate will both further develop existing mail systems while collaborating with cross-functional engineering teams to define and implement new mail anti-abuse systems.
There have been some hiccups with Apple’s iCloud mail service in the past (apart from frequent iCloud service outages), including a problem with the service’s automated spam filters that caused legitimate emails to be sent to spam. Apple does have a way for users to report spam and set up filters with iCloud mail, but complaints of users frustrated with spam have continued.
