Senior Site Reliability Engineer

At Apple, we strive every single day to craft products that enrich people's lives. Our successes are the result of skilled domain experts working in an environment which encourages creativity, collaboration, and re-thinking of old problems in new ways! As a member of the Satellite Connectivity Group, you will work on the satellite network that enables connectivity to iPhone when off the grid and without cellular or Wi-Fi coverage. Every day, Apple customers use Emergency SOS via satellite to access emergency assistance when they are in need of help and have no other means to communicate. You will have the unique and rewarding opportunity to shape this and other critical services, to the benefit and safety of millions of Apple device users.

Description

Apple is looking for an SRE (or Software Engineer) to join a small passionate team that builds, monitors, automates, and maintains a sophisticated system for a critical and unique customer-facing Apple service. This is a rare opportunity to help build and run systems and software for a service that customers will rely on every day on a team with a no-ops culture. We're looking for people who like to solve operational problems using software rather than shell prompts as we scale Apple's services. You should be a forever learner with a bias toward action and positive energy. Job duties include participating in on-call rotations occasionally. Help us build the Apple experience on a global scale!
