What a MongoDB developer does on our teams
A MongoDB developer on our team owns the data layer of a Node.js or Python product built on MongoDB. They shape documents around the screens and APIs that read them, choose what to embed and what to reference, and add the indexes that keep queries off collection scans. They also set up tenant isolation and keep Atlas costs in check. On Edge OCR, an AI document processing SaaS, every organisation gets its own MongoDB database. Dynamic model loading, per-tenant connection pooling and a circuit breaker keep one customer's load from affecting another's. Solas, a funeral management SaaS, uses business-scoped Mongoose schemas so each funeral home sees only its own records. The influencer marketing platform runs on MongoDB with Mongoose and Redis behind a Node.js API.
How we assess MongoDB developers
- Data modelling: design documents for a realistic feature such as orders with line items and status history, and justify embed versus reference
- Performance: read an explain plan, add a compound index in the right field order and remove a collection scan
- Aggregation: build a reporting pipeline with lookup, group and facet stages that stays fast at a million documents
- Operations: transactions, change streams, backups, Atlas alerts and multi-tenant isolation
- Sample task: fix three slow queries and add a tenant-scoped aggregation with tests in four hours

SolasEnterprise · OperationsHiring MongoDB developers, answered.
MongoDB or PostgreSQL for a new product?
PostgreSQL when the data is relational and needs joins and strict constraints; MongoDB when documents vary a lot in shape or are read and written as a whole. We say which in discovery and build on either.
Can they work with MongoDB Atlas?
Yes. Cluster sizing, backups, alerts, Atlas Search and Vector Search, and network and access configuration, in your Atlas organisation.
Can you migrate us from MongoDB to PostgreSQL?
Yes. We map documents to tables, run both side by side with a backfill and a change stream sync, compare results, then move reads and writes in stages. Our PostgreSQL developers handle the target side.
