We are supporting a consultancy delivering a large-scale data modernisation programme and are looking for a MongoDB Engineer to join the team.

The role will focus on implementing, migrating, and optimising MongoDB solutions as part of a broader move from a monolithic architecture to a microservices-based design within MongoDB Atlas.

Key responsibilities:

• Deliver hands-on MongoDB engineering, configuration, and optimisation
• Support data migration activities and ensure data integrity across microservices
• Implement indexing, replication, and sharding strategies
• Collaborate with architects and developers to translate data designs into working solutions
• Monitor and tune performance within MongoDB Atlas
• Contribute to automation, documentation, and continuous improvement activities

Experience required:

• Strong experience with MongoDB and MongoDB Atlas environments
• Proven track record delivering data migrations and optimisations
• Knowledge of data modelling, indexing, and replication
• Familiarity with microservices architectures and distributed systems
• Understanding of performance monitoring and security configuration
• Experience working in agile delivery environments

This is a hands-on engineering role offering the opportunity to contribute to a high-profile migration to MongoDB Atlas within a modern microservices architecture.
