Senior Embedded Linux / Yocto Engineer

We’re a small, highly experienced team that built the operating system for the most sophisticated

beverage dispenser in the world, made by the largest beverage company in the world (We can’t tell you

who they are, but we’re in Atlanta). Now we’re at it again, but this time we’re building a Linux-based

distributed operating system to unify all equipment purchased by this beverage company. Along the

way we’ve completely re-imagined how to build Linux devices. Are you still using A / B partitions for

updates and rollbacks? We invented a way to de-dup releases and store an arbitrary number in a single

partition. Need to test real hardware in a simulator, or access hardware from a different node in a

distributed device? Our hardware abstraction is network transparent so we’ve got you covered. Want to

run x86 on your laptop but push to your arm64 dev board? Just enter the IP address and our Studio

application will sort out all the details and install to any target across the network. Incremental OTA,

manifest based deterministic runtime, immutable layer based filesystems, universal logging

infrastructure with support for real time streaming over the network, fully routed websocket mesh

networking, multi-node devices and many other inventions that push the boundaries of what is possible

on a Linux device. We’re looking for someone to help us integrate even deeper into Linux as we invent

and deliver the future!

About the Role

Our goal is to transition our Yocto stack from our partner organization to an internal resource so we can

focus on deeper integrations and continue our work on distributed platforms (devices that contain more

than one Linux board). Our partner remains engaged and will provide training and transition support. In

this role, you will be an integral part of our architecture team, contributing to high level designs and

solutions, such as auto-creation of a mesh VPN network for distributed devices, as well as execution of

deliverables such as upgrading to new Yocto versions, board ports and inclusion of new packages in our

build. As we put a great deal of focus on operational infrastructure in our Studio product, there is also

an emphasis on capturing operational state of the OS and reflecting it in our tooling.

Primary responsibilities

Support, extend and update our Yocto based infrastructure, including new Yocto releases, new

board support and exposing new libraries and packages.

Work closely with our internal teams to design, document and deliver new features.

Build, branching and publishing related to creating releases of os components.

Debugging integration related issues such as performance (video, browser, etc…) and stability

(library compatibility, crashes, etc…).

Learn, understand and contribute to our overall platform architecture.

Qualifications

B.S. in computer science and five years related work experience
