The Platform Engineering group within Enterprise IOT supports the reliability, security, scalability, and efficiency of our applications, infrastructure, and devices in cloud and retail environments. 
This role is new on our team. It is being added to help build highly automated capabilities for hands-off operation of a large, distributed fleet of Linux OS instances, in advance of initiatives that will result in tens of thousands of new devices in our retail stores. 
The Linux Platform Engineer will play a significant role in defining needs, choosing technical approaches (utilities, libraries, etc.) and implementing tooling & automation. This will include ongoing collaboration with other Plat Eng and Product Dev engineers to collect input, review designs, and contribute requirements for scripting or development efforts by others in support of this work.

Job Duties -

Key areas of focus for this role include: 
? OS standard build & image – configuration, hardening, baked-in software, image
packaging 
? Headless recovery capability – self-testing, automated reimage/rebuild 
? Observability – health & performance monitoring, logging, integration with existing SaaS
platform 
? No-touch management – script common admin, maintenance, reporting, and
troubleshooting tasks that can be scheduled or wired into existing remote-trigger
mechanisms, with success/failure events and harvested information pushed into
logging/monitoring 
? Certificate / key distribution and management – contribute to overall system design,
build necessary OS-side tooling for the overall system. 
The role also includes documentation tasks, as well as a small amount of day-to-day production support
and break-fix work, particularly in earlier phases before operations are fully automated.
