Sr. Scala Backend Developer
Greenwood Village, CO, USA
In-person interview
Strong Scala backend engineer with microservices experience to work in a small, agile team. The team develops client-facing REST APIs that provide data for IP TV (television over the internet), for functionality such as consumer entitlement verification, on/off-net verification, parental control verification, and settings.
The technology stack includes Scala, Scalatra, Memcached, Kafka, MongoDB, docker, Kubernetes, Splunk and Datadob. All code is written in a functional style and is fully asynchronous using Scala Futures. The team works at scale, handling hundreds of millions of REST calls per day.
Engineers on this team create new microservices and improve existing microservices. Projects are usually of considerable complexity and require a mastery of development tools. Engineers are expected to design and implement scalable, dependable systems as needed. As this is a small team, engineers must be self-starters, capable of handling responsibility and making decisions.
If your candidate has STRONG SCALA and KAFKA and none of the other skills I will still submit.
