As a Senior Cassandra Architect, you will act as a key SME for general NoSQL technologies, with a focus on products such as Cassandra and Solr. This candidate is expected to be a Senior Engineer, Architect, and Technology Leader who can play many roles throughout a product or project lifecycle and is not simply a Database Administrator. Candidate must be comfortable with hands-on support for new Proof-of-Concept efforts in addition to supporting existing internal business and technology partners. Candidate should also be able to specify hardware for performance optimization and advising on tuning parameters throughout the hardware/software stack.

Candidate must be comfortable addressing a variety of audiences and adjust his/her communication style accordingly. Candidate should also be able to establish emerging technology blueprints and reference architecture documentation for NoSQL database products while also supporting those products in a production environment. Able to support frequent deployments through automation and an ability to work in uncharted territory with new technologies. The candidate will be the go-to person on high priority projects, and must be able to balance priorities and shifting requirements with minimal direction. The ability to independently learn and thrive in a fast-paced environment is a must!
