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 including the Linux kernel, device drivers, RTOS, and bootloaders. You will partner with SoC vendors on low-level platform enablement and optimize software for resource-constrained hardware.

What you'll do

• Own the foundational operating system layer including Linux kernel, device drivers, RTOS, and bootloaders
• Optimize for boot time, memory footprint, and power efficiency on resource-constrained hardware
• Partner with SoC vendors on low-level platform enablement

Tap what's true for you. Your answers are saved for every other job too.

Put these words in your resume and practise these questions before the interview.

Technical

1. How does the Linux kernel manage memory in resource-constrained embedded systems?
2. What are the key differences between scheduling policies in a Real-Time Operating System (RTOS) versus standard Linux?
3. How would you approach debugging a device driver crash during the bootloader phase?

Scenario

1. What would you do if a new connected device build exceeds the target memory footprint during boot?
2. How would you troubleshoot an unexpected increase in power consumption on a resource-constrained hardware prototype?

HR

1. Can you describe a challenging low-level debugging problem you solved in a systems programming project?
2. Why are you interested in working on foundational device software and embedded systems at Amazon?

About Amazon

1. How does Amazon's approach to designing Alexa and connected hardware devices influence your choice of operating system optimizations?
