Software Development Engineer, Alexa Connectivity Devices

We are building a new device software team in Bangalore to power the next generation of Amazon connected devices. As an OS / Kernel Engineer you will own the foundational operating system layer Linux kernel device drivers RTOS and bootloaders on which all device software depends. You will optimize for boot time memory footprint and power efficiency on resource-constrained hardware and partner with SoC vendors on low-level platform enablement.



Key job responsibilities
Develop and maintain Linux kernel configurations device drivers and board support packages (BSPs)

Optimize boot time memory footprint and power consumption at the OS level

Implement and maintain bootloader chains (U-Boot custom) with secure boot support

Port and adapt RTOS components (FreeRTOS Zephyr) for companion microcontrollers

Debug kernel panics race conditions memory leaks and other low-level system issues

Collaborate with SoC vendors on kernel patches errata workarounds and BSP updates

Own kernel upgrade strategy and long-term support (LTS) branch management

A day in the life
As a member of the leadership team you will serve as the technical leader for device software development and operations. You will collaborate with stakeholders across Alexa Devices and Alexa Cloud teams to define roadmaps plan requirements make prioritization trade-offs and feature development. You will partner with principal engineers to brainstorm solutions solve problems and deliver features.
