Senior Software Engineer - Location Technologies, Sensing & Connectivity

Summary

The Sensing and Connectivity Location team creates the software and infrastructure that powers positioning on Apple products. Through the integration of multiple on-device sensor suites, broad network provisioned aiding, and state of the art estimation and fusion algorithms, our team enables precise workouts, pinpoint mapping, and accurate navigation wherever the user desires to go.

Description

In this role, you will advance the accuracy and availability of Apple's on-device location services via curated, network-delivered aiding data to close gaps in the device's knowledge of its environment and operating context.

Responsibilities

• Define and drive the development of network data services and develop the back-end algorithms that animate them.
• Build and maintain monitoring, alerting, and data-quality tooling for production services, in partnership with other internal location teams.
• Own technical relationships with external data vendors or partners.
• Support qualification and commercialization of location-service features, including integration of on-device sensor and telemetry data, shipped to iPhone, iPad, and Apple Watch.

Minimum Qualifications

• BS or MS in EE, CS, Aerospace, Geomatics, or equivalent, plus 5+ years of software or positioning experience.
• Strong software development skills: C/C++ for embedded, Java for server-side, and/or Python for data analysis and visualization.
• Demonstrated depth in at least one of the following, plus working familiarity with the other two:
• 1. GNSS positioning concepts and ephemeris/orbit data.
• 2. Cloud-based service design and operations (AWS, GCP, Azure, or equivalent).
• 3. Production monitoring, alerting, and data-quality systems.

Preferred Qualifications

• Working knowledge of RF or alternate location-sensing technologies beyond GNSS.
• Experience developing or shipping software for embedded or consumer hardware platforms.
• Experience with crowd-sourced, sensor, or telemetry data systems.
• Experience working directly with external vendors or partners on technical data-integration efforts.
• Experience presenting technical findings or recommendations to management or non-technical audiences.
• Experience leveraging GenAI and Agentic work flows to development and analysis tasks.
• Genuine passion for location technologies and a drive to continuously innovate in ways that make a real difference in people's lives.
