Apple is where individual imaginations gather together, committing to the values that lead to great work. Every new product we build, service we create, or Apple Store experience we deliver is the result of us making each other’s ideas stronger. That happens because every one of us shares a belief that we can make something wonderful and share it with the world, changing lives for the better. It’s the diversity of our people and their thinking that inspires the innovation that runs through everything we do. When we bring everybody in, we can do the best work of our lives. Here, you’ll do more than join something — you’ll add something. Join the Siri Attention and Invocation team and play a part in the next revolution of Siri interaction. We are a group of engineers dedicated to making Siri an exceptional conversational partner and an attentive listener, focusing on innovative multimodal machine learning solutions that enhance user experiences across Apple's entire device ecosystem. Here, you'll do more than join something—you'll contribute something meaningful to a technology that helps millions of people get things done, just by asking. Siri Attention and Invocation's Platform team is seeking a passionate software engineer to shape the foundational platform on new hardware. Our team develops the platform that powers Siri's natural and conversational features across all Apple devices and operating systems. In this role you will architect elegant solutions to complex system-level challenges, solve critical issues across the technical stack, and help make critical decisions that will define user experience. You will work with software engineers, machine learning engineers, and scientists across technical areas spanning the full range of Siri's capabilities. You will work with exciting new hardware; and closely partner with silicon, firmware, hardware, and software teams to explore strategic intersection areas, and build Siri features that work seamlessly creating unique, powerful and secure user experiences. While this role involves working with hardware, your focus will be on higher-level software — not on firmware or embedded systems development.

You'll join a team that develops the front door to Siri experience. As a software engineer you will be developing and maintaining the on-device platform that powers Siri features aimed at making Siri attentive and conversational. Your day-to-day will involve developing an efficient framework that will integrate Siri audio, and support run-time execution of various machine learning models that are at the core of a Siri interaction. You will develop algorithms and run experiments aimed at improving Siri invocation, and make latency/accuracy trade-offs that directly affect user experience. You'll drive software features across the full development cycle — from prototype to production —each phase presenting distinct challenges and learning opportunities. As part of a fast-moving, intellectually curious team, you'll play a key role in reimagining how millions of people interact with Siri.
