SSE-MongoDB

About the Role

We are looking for a skilled MongoDB Developer with strong experience in designing, optimizing, and implementing document-based data solutions. The ideal candidate should have hands-on expertise in MongoDB data modeling, query optimization, performance tuning, and integrating MongoDB with .NET/C# applications. This role involves building scalable, secure, and high-performance data systems to support enterprise-grade applications.

Key Responsibilities

• Design efficient, scalable, and flexible MongoDB schemas using best practices for normalization and denormalization.
• Implement CRUD operations, including advanced querying, filtering, sorting, pagination, and bulk operations.
• Build and optimize indexes, analyze query performance, and interpret execution plans for performance tuning.
• Develop data access layers and integrations using MongoDB .NET/C# drivers.
• Implement upserts, replacements, aggregation pipelines, and data transformation workflows.
• Work with MongoDB Atlas, including replication, sharding configurations, and deployment tuning.
• Manage data lifecycle strategies: hot/warm/cold storage tiers, TTL indexes, and archival mechanisms.
• Implement backup/restore routines, monitoring, and alerting using Atlas or Ops Manager.
• Work with change streams for real-time event-driven data pipelines.
• Ensure security best practices including authentication, authorization, auditing, and compliance.
