Must Haves:

o   This is an infrastructure focused role you will need experience in the following:

§  Knowledge of container orchestration and distributed systems such as Kubernetes & Docker;

§  Mastery of Python or a similar backend language (e.g. Ruby, JavaScript/Node.js, Golang, Lua, Dart, PHP, C#, Java, Lua).

Nice to Have:

·       Experience with: gRPC, Bazel build, Jenkins, ThingsStack, ChirpStack, LoRa, MachineQ;

·     Experience with deploying, releasing, and supporting software in production (preferably with Kubernetes and/or Docker);

·       Prior IoT or hardware experience - it’s nice if you have some, but most of the time we're interacting with devices through APIs. The engineering teams primarily works on the cloud-side components for interacting with IoT devices and typically does not write software to run on the devices themselves.


Work Experience

Candidates can demonstrate that they are qualified by having both of the following and one of the other skills:

·       5+ years required 10+ years preferred experience writing and supporting code that is deployed and in production;

·       10+ years experience in infrastructure management, development, and deployment;

Our team is driven to serve our clients so families across the globe enjoy their safe, comfortable homes.   How do you acclimate a new hire in a remote working environment?
