Job Summary

Experienced Database Architect to lead the modernization of its flagship product, which currently uses the object-oriented database, to a modern, scalable object-oriented data platform such as MongoDB (or equivalent).

This role is critical to defining the target data architecture, migrating complex object models, and ensuring performance, scalability, and long-term maintainability of data layer.

The architect will work closely with product engineering, CAD domain experts, and solution architects to deliver a robust database transformation.

Key Responsibilities

- Own the end-to-end database architecture for migrating existing OODBMS to MongoDB or a suitable object-oriented NoSQL database
- Analyze existing object schemas, relationships, inheritance hierarchies, and lifecycle behaviors
- Define target object-oriented data models optimized for MongoDB, including:
- Embedded vs referenced objects
- Inheritance and polymorphism strategies
- Versioned object structures
- Design and implement data migration strategies ensuring:
- Data integrity and consistency
- Minimal downtime and risk
- Backward compatibility where required
- Define standards for:
- Schema evolution and versioning
- Indexing, sharding, and replication
- Performance optimization for CAD-heavy workloads
- Collaborate with application teams to align object persistence patterns with MongoDB access patterns
- Architect high-availability and scalable MongoDB deployments (on-prem and/or cloud)
- Validate performance, scalability, and correctness of the new database architecture
- Produce architecture documents, migration playbooks, and technical guidelines
