work-life balance.\nOffer excellent benefits!\nMinimum Qualifications\nB.S. in Computer Science or equivalent experience\n5+ years of relevant industry experience\nProfessional expertise in software engineering\nSkilled with one or more advanced programming language such as C, C++, Java or Go\nFull product lifecycle ownership mindset (design → implementation → production)\nExperience with core production engineering best practices (e.g., designing for operability and scalability, adopting SLOs, eliminating toil).\nPreferred Qualifications\nPassionate about improving the team and partners you work with.\nExtensive professional expertise in Traffic/Edge Engineering or Cloud Networking\nExpertise and experience in developing extensions/filters for Envoy\nProven expertise with Linux network stack\nUnderstanding of performance analysis and optimizations\nPassionate about enabling internal partner teams\nPassionate about contributing to open source projects such as Envoy (http://envoyproxy.io/ (http://envoyproxy.io/)) and working across a large organization to meet Apple’s dynamic traffic
