Senior Engineer, Satellite Resource Optimization

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 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.

Apple is seeking a Senior Engineer with wireless and software engineering experience to join our Satellite Communications Group radio algorithm optimization team. Our team develops the network layers, monitoring systems, and large‑scale resilient infrastructure that enable customers to access critical communications services via satellite—even in the most remote  this role, you will architect and implement scalable solutions that optimize global satellite resource usage.

You'll design algorithms and systems that balance efficiency, reliability, and customer experience in a distributed architecture supporting unique, customer‑facing Apple services.

This is a highly visible role where your work directly impacts users in critical situations, offering the opportunity to solve complex technical challenges at the intersection of satellite communications, distributed systems and resource optimization.

• Design and implement algorithms for efficient satellite resource allocation and network optimization across global infrastructure
• Develop and optimize network protocols and layers for satellite communication systems
• Build monitoring, telemetry, and automation systems to track performance and resource utilization at scale
• Analyze system performance data to identify bottlenecks and implement algorithmic improvements
• Collaborate with RF engineers, operations teams, and product managers to define requirements and deliver end‑to‑end solutions
• Participate in technical design reviews, contribute to architectural decisions, and mentor team members
• Support production systems through on‑call rotation and drive continuous improvement initiatives

• Deep expertise in distributed systems architecture and implementation, particularly in satellite networks or similar large‑scale communication systems
