Imagine what you could do here. At Apple, we believe new insights have a way of becoming excellent products, services, and customer experiences very quickly. Bring passion and dedication to your job and there’s no telling what you could accomplish. The people here at Apple don’t just create products — they create the kind of wonder that’s revolutionized entire industries. It’s the diversity of those people and their ideas that inspires the innovation that runs through everything we do, from amazing technology to industry-leading environmental efforts. Join Apple, and help us leave the world better than we found it. 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.
- Drive reliability, observability, and clean failure recovery to keep test execution predictable across the entire lab footprint
- Provisioning new hardware, benches and managing software/firmware lifecycle
- Equipment support : Maintain calibration integrity from source to receiver, owning the environment where every test run is trusted, repeatable, and production-representative.
- Ensure new hardware, benches come online quickly and existing benches stay up-to-date with evolving tooling, dependencies, and test requirements
- Troubleshoot configuration failures, integrate infrastructure changes with CI and test orchestration systems, and partner with IT, networking, and lab ops teams
- Root-Cause Analysis — Debug GNSS/cellular/Wi-Fi positioning logs to isolate regressions; develop custom analysis scripts and statistical models to quantify impact.
- 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 ,with development of custom analysis scripts considered a plus
- Ability to drive cross-functional communications and understanding dependencies while also ensuring a tight timeline can be maintained
- 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.
