Senior Backend Systems Engineer, Sensing & Connectivity

Apple Apple · Big Tech · San Diego, CA +1 · Software and Services

This role focuses on building backend systems for location intelligence, processing sensor data, and applying ML to extract insights. It involves owning the full ML lifecycle from problem formulation to production deployment, with a strong emphasis on software engineering and distributed systems at scale.

What you'd actually do

  1. You'll architect and build backend systems that process crowdsourced sensor data from hundreds of millions of devices, fueling algorithms that solve problems from everyday navigation to life-critical emergencies.
  2. You'll propose ideas, crunch data, leverage modern AI tools, and ship systems that run under demanding real-world efficiency requirements at global scale.
  3. You'll design, build, and maintain high-quality, production-grade software systems — writing well-architected, testable, and performant code that others on your team rely on every day.
  4. You'll design and build signal processing pipelines and data infrastructure that ingest and interpret crowdsourced sensor data from hundreds of millions of devices — and apply ML to extract intelligence from those streams at scale.
  5. You'll own the full ML lifecycle: from problem formulation and feature engineering on raw sensor data, through model development and experimentation, to building the infrastructure that takes models reliably into production.
