Novia Infotech is seeking a highly experienced Senior MongoDB DBA to lead the design, configuration, and optimization of enterprise-scale database environments. This role is critical for maintaining the health and performance of our data infrastructure across our Sunnyvale, CA and Austin, TX locations. The ideal candidate will bring deep expertise in MongoDB architecture, specifically focusing on sharded clusters, replica sets, and high-security implementations within Linux and AWS environments.
Core Responsibilities and Technical Leadership
- Cluster Architecture: Design and configure multi-node MongoDB replica sets and complex sharded clusters. You will be responsible for converting replica sets to sharded clusters to support massive data growth.
- Sharding Strategy: Implement sophisticated range-based and hash-based sharding strategies, ensuring even data distribution through optimal shard key selection.
- Ops Manager Administration: Configure and manage MongoDB Ops Manager, including Backup & Restore Service (BRS) and cluster onboarding.
- Security Implementation: Enforce enterprise-grade security using X509 authentication and TLS/SSL encryption across all mongod instances.

Essential skills include in-depth knowledge of MongoDB replication architecture, strong Linux administration experience, and proficiency in scripting languages like Python. You must be comfortable performing major version upgrades (e.g., 4.0 to 4.x) and operating within secure, compliance-heavy enterprise frameworks. The role requires a proactive approach to monitoring cluster health and the ability to document complex security configurations and audit processes for stakeholders.
