We are looking for a skilled NoSQL Database Administrator (DBA) to join our technology team. The ideal candidate will be responsible for the installation, configuration, maintenance, and performance tuning of NoSQL database systems such as MongoDB, Cassandra, Couchbase, DynamoDB, or similar platforms. You will work closely with developers, system architects, and IT operations to ensure database reliability, scalability, and security.
As a NoSQL DBA, you will monitor database performance, implement backup and recovery strategies, and troubleshoot issues to minimize downtime and data loss. You will also be expected to automate routine tasks, optimize queries, and design data models that support high availability and disaster recovery. Your role will involve collaborating with cross-functional teams to design and implement database solutions that meet business requirements and support application development.
The successful candidate should have a deep understanding of NoSQL database architectures, data replication, sharding, and indexing strategies. You should be comfortable working in cloud environments and have experience with database-as-a-service offerings. Strong scripting skills, knowledge of security best practices, and the ability to document and communicate complex technical concepts are essential.
This role requires a proactive approach to problem-solving, a keen attention to detail, and the ability to stay current with emerging database technologies. If you are passionate about database administration and eager to work in a dynamic, fast-paced environment, we encourage you to apply.
