WHAT YOU'LL DO
The MongoDB Database Administrator (DBA) role is part of the Platform Engineering division within Infrastructure and is responsible for operating, scaling, and securing our internal MongoDB platform. This position supports a growing fleet of MongoDB clusters that back product-critical features, internal systems, and distributed services.
This role partners closely with SREs, application engineers, and the platform security team to ensure MongoDB clusters are performant, resilient, compliant, and well-automated. Our clusters run on a modern Kubernetes-based infrastructure and are managed through GitOps and infrastructure-as-code practices. The DBA will help evolve and mature the platform, support backup and disaster recovery strategies, and assist engineers in designing efficient, durable MongoDB usage.
Main responsibilities:
1) Cluster Operations & Reliability:
- Operate production MongoDB clusters running in Kubernetes across multiple regions and clouds
- Monitor cluster health, performance, replication, and storage usage, and proactively address degradation
- Debug and resolve availability, latency, or data consistency issues in partnership with SREs
- Participate in on-call rotations as a subject matter expert for MongoDB infrastructure
2) Automation & Tooling:
- Automate routine operations such as database user management, cluster scaling, version upgrades, and backup restores
- Maintain and improve internal tooling used for MongoDB observability, lifecycle management, and access control
- Collaborate with Platform Engineering on Kubernetes-based deployment patterns and GitOps workflows
3) Backup, Restore & Disaster Recovery:
- Implement and maintain point-in-time recovery, daily snapshots, and cross-region backup strategies
- Regularly validate restores and participate in resilience exercises and disaster recovery planning
- Partner with Security and Compliance teams to ensure backups meet RTO/RPO targets and audit requirements
4) Engineering Support & Best Practices:
- Assist product engineering teams with schema design, indexing strategies, and performance tuning
- Promote internal best practices for efficient queries, data modeling, and shard key design
- Document operational runbooks, configuration standards, and performance baselines
WHO YOU ARE
Experience:
- Relevant proven work experience managing MongoDB in production environments at scale
- Strong working knowledge of replica sets, sharding, WiredTiger storage engine, oplogs, and journaling
- Experience operating MongoDB in cloud or containerized environments (Kubernetes preferred)
Skills:
- Comfortable with automation and scripting in languages like Bash, Python, or Go
- Proficient with MongoDB CLI tools, Atlas APIs, and backup/restore tooling (e.g., mongodump, mongorestore, mongosh, Ops Manager)
- Familiar with observability stacks (e.g., Datadog, Prometheus, Grafana) and alerting strategies
- Experience with GitOps workflows and infrastructure-as-code tools (Terraform, Helm, ArgoCD) is a plus
Mindset:
- Detail-oriented and reliability-focused: treats data loss and downtime as unacceptable
- Strong communicator: able to document clearly, partner cross-functionally, and lead incident response
- Growth-oriented: comfortable evolving systems, adopting new automation, and supporting other engineers
Bonus qualifications:
- Experience with other database platforms (e.g., PostgreSQL, MySQL, DynamoDB)
