Apple services need world class libraries in order to operate in a distributed, performant, and reliable fashion. We are responsible for delivering the libraries that meet the needs of Apple services. Examples of these libraries are Netty (https://netty.io/) and ServiceTalk (https://servicetalk.io/). Our team is passionate about enabling our partners, whether that's delivering library changes, configuration changes, or guiding our peers on how to tune their applications. If you are interested in digging into networking protocols all the way up to exposing these capabilities in a user friendly fashion then we'd love to hear from you!
As a software engineer you will contribute to and build libraries that enable services at Apple's scale. This is an opportunity to develop and demonstrate your leadership skills, influencing and improving the networking stack for Apple services. You will have the opportunity to work with a team which is focused on impact across Apple. Engineers will learn how to excel at making informed technology choices within complex architectures. You will develop deep understanding of the organization's business, products, customers, and strategy will empower us to pinpoint opportunities aligning with our team's mission. Navigating ambiguity is our strength - you will gain skills on how to concentrate on the broader objectives, goals, and desired impact, taking deliberate steps forward. Our dedication extends to coaching and mentoring teammates, considering their unique skills, backgrounds, and working styles. You will actively seek and provide constructive feedback to foster growth within our team.
