- Strong experience administering and supporting MongoDB environments, including performance tuning, backup and recovery, and replication.
- Programming experience in one or more languages commonly used with MongoDB, such as Java, Python, Node.js or C#.
- Experience supporting development teams through onboarding, solution design, testing and production issue resolution.
- General platform engineering experience, such as automation, scripting, CI/CD, and working with cloud or containerised environments.
- Working knowledge of database activities including bulk data loading and data migration.
- Experience with MongoDB Atlas is preferred but not essential.
- Strong communication and stakeholder engagement skills, with the ability to give practical guidance to delivery teams.
