We are seriously considering using Cassandra for our non-relational datastore. We have some ideas about how we want to model our data within Cassandra, but no one on my development team has ever worked with Cassandra before. I am looking to hire someone with prior significant architect experience working with Cassandra. You will be working with my team of Engineers and help guide us to the best approach for modeling our data. Prior experience with other non-relational datastores is a huge plus. It's possible that Cassandra isn't the right choice (we believe it is). You will be helping us make those calls. If you are not in the western hemisphere, you will need to make yourself available for phone calls or video calls to discuss the architecture with our team during our working hours. Our development office is in the US Mountain Timezone (GMT-6). We normally work the hours of 9:00 - 18:00 GMT-6. Depending on where you live, this may be in the middle of your night.

Hi! We are developing a new corporate application and are looking for strong developers to join our team. Out technology stack consists of: - CouchDB backend (no-sql DB, coding in js, 2600 lines of code) - Python based API (flask, about 10k lines of code) - AngularJS frontend (bootstrap, angular coded in coffeescript are the main components, 5300 lines of coffee, 5600 html) - The development environment resides in Docker. The main challenges at the moment are CouchDB (it requires a very different thinking about algorithms than standard SQL, coding itself is easy if you know js) and the API (which requires clean-up, simplification and more consistency). We are working in a very agile and distributed way, i.e., part of the team is located in Zurich, Switzerland, part of it in St. Petersburg, Russia. Our goals are clear, but we constantly work together on making the product better (user friendly, efficient, secure) and have a long list of desired features.
