Distributed Systems Software Engineer (Golang)

San Diego, California, United States Software and Services

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 and Watch Ultra when off the grid without cellular or Wi‑Fi coverage.

Every day, Apple customers use Emergency SOS, Roadside assistance, and Messages via satellite to stay connected when they 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. You will build and run an Apple service enabling platform that millions of customers may rely on every day.

You’ll also build and run the infrastructure that powers those services with emphasis on build, not just operate or implement. We’re looking for people who like to solve problems using software rather than shell prompts as we scale Apple’s services for customers around the world. Help us build the Apple experience on a global scale!

Apple is looking for a Senior Software Engineer with distributed systems and orchestration experience to join the Satellite Communications Group. Our team builds, monitors, and maintains large scale, highly resilient systems that enable our customers to access communications services via satellite. You’ll be contributing to distributed systems, architecture design, and cloud infrastructure (as code!) for critical and unique customer‑facing Apple services.

This is a rare opportunity to build and control the entire end to end infrastructure, along with all supporting components such as provisioning, monitoring, deployment, and software platforms, from the beginning within a team with a no‑ops culture.
