Role Number:

200681599-0836 Part of what makes AirPods amazing is how effortless they are to use. Put them in your ears and they know they're being worn. Press or swipe the stem and they respond naturally. Start a workout and they can measure your heart rate. Behind these seemingly simple experiences are challenging problems across sensing, algorithms, real-time firmware, custom silicon, and system software.

The Human Interface Devices (HID) AirPods Firmware team is looking for an experienced firmware engineer to architect and build the embedded systems powering these sensing and interaction technologies. You will work across the entire product lifecycle — from early technology exploration through mass production — collaborating with multidisciplinary teams to create intuitive experiences used by millions of customers. Description As a Senior Firmware Engineer on the HID AirPods Firmware team, you will own critical sensing and interaction technologies, developing the real-time, power-efficient embedded software that turns physical sensor inputs into intuitive customer experiences. You will architect and deliver robust C/C++ firmware, bring up and characterize new sensing technologies, integrate algorithms, and solve complex system-level problems spanning sensors, custom silicon, firmware, and higher-level software. Responsibilities Your responsibilities will span from low-level

bring-up, to delivering best-in-class customer experiences built on foundational sensing technologies. You will develop the instrumentation and tools needed to characterize system behavior and ensure features perform reliably across real-world conditions, while partnering across disciplines to take new technologies through validation and mass production. You will also help define what comes next. Working closely with silicon and hardware teams, you will influence future system architectures and translate firmware and product needs into capabilities for next-generation sensors and custom silicon. As a senior member of the team, you will provide technical leadership through architecture and design reviews, cross-functional technical direction, and mentorship of other engineers.
