About The Position

Our Sensing and Connectivity team is seeking a Software Integrity Engineer to validate and advance the next generation of location algorithms powering every Apple product. Our proprietary positioning stack fuses GNSS, Cellular, Wi-Fi, and Bluetooth signals to deliver the location experience behind Maps Navigation, Fitness applications, Emergency SOS via Satellite, and more. As a Software Integry engineer, you will directly measure, characterize, and improve the accuracy, reliability, and performance of these algorithms — ensuring hundreds of millions of users can trust the blue dot. The Software Location QE team operates at the intersection of algorithm development and quality engineering. We design experiments, build analysis pipelines, and run validation campaigns that prove (or disprove) that location algorithms meet Apple's rigorous standards across real-world and simulated environments. We're looking for an engineer with a deep understanding of what quality means for GNSS positioning. You will play a hands-on role in sustaining the operational foundation of our validation infrastructure, owning the health, configuration, and readiness of devices, test rigs, and receivers to ensure continuous, uninterrupted test execution.

Requirements

• Bachelor's degree in Computer Science, Electrical Engineering, Applied Mathematics, or equivalent experience
• 3+ years of experience in GNSS testing, positioning validation, or wireless system verification
• Proficiency in Python for data analysis, scripting, and automation
• Experience with GNSS/A-GNSS simulation equipment (Spirent, LabSat) and live signal roof top testing for functional & performance validation
• Familiarity with QA methodologies and test automation strategy
• Experience in debugging logs to triage and root-cause issues
• Ability to drive cross-functional communications and understanding dependencies while also ensuring a tight timeline can be maintained

Nice To Haves

• Development of custom analysis scripts
• Experience in design and development of automated test harnesses & data analysis tooling
• Knowledge of the chipset validation lifecycle, from silicon bring-up through production-level algorithm tuning
• Understanding of A-GNSS protocols, multi-constellation processing (GPS, Galileo, GLONASS, BDS), and sensor-fusion architectures
• Knowledge of machine learning algorithms and novel genAI techniques that can be leveraged for automation and analysis
• Ability to read and interpret 3GPP location-service specifications (LPP, SUPL) and translate logs to verify misses against conformance requirements
• Excellent written and verbal communication skills; comfortable presenting algorithm validation results to cross-functional audiences
• Prior experience in fast-paced, agile environment with the flexibility to pivot quickly to support evolving product requirements

Responsibilities

• Sustain the operational foundation of our validation infrastructure
• Own the health, configuration, and readiness of devices, test rigs, and receivers to ensure continuous, uninterrupted test execution
• Design experiments, build analysis pipelines, and run validation campaigns
• Measure, characterize, and improve the accuracy, reliability, and performance of location algorithms
