About the Role
Nium is looking for a Senior Database Administrator (DBA) to lead the architecture, performance, and reliability of our PostgreSQL, MongoDB, RedShift and other database platforms hosted on AWS (primarily RDS/Aurora). You'll play a critical role in enabling modern, automated, and resilient database operations that support our engineering and analytics teams.
This is not your traditional DBA role — we're looking for someone who brings both deep database internals knowledge and modern practices like DBOps, schema versioning, infrastructure-as-code, and database CI/CD.
You’ll collaborate closely with DevOps, SREs, and Developers to streamline deployments, improve observability, and build a scalable data platform.
Responsibilities
- Architect, manage, and scale cloud-native PostgreSQL and MongoDB clusters (primarily AWS RDS/Aurora, MongoDB Atlas)
- Implement and maintain schema change automation using tools like Liquibase, Flyway, or equivalent
- Collaborate with engineering teams on schema design, query optimization, indexing strategies, and ORM tuning
- Establish and evolve database CI/CD pipelines integrated with GitOps practices
- Monitor database health and performance using observability tools such as CloudWatch, Datadog, Prometheus/Grafana, or pg_stat_statements
- Drive automation for routine operations: failover, backup validation, data masking, role management, etc.
- Manage and secure database environments with IAM, KMS, and encrypted connections
- Plan and execute migration strategies (engine-to-engine, sharded or replicated setups)
- Document architecture, runbooks, schema evolution, and disaster recovery plans
- Support compliance needs (e.g., audit logging, PCI-DSS, GDPR/data retention policies)
- Coach developers and data analysts on best practices for schema evolution, query design, and performance debugging
Requirements
- 5+ years of production experience with PostgreSQL, MongoDB, and MySQL including high-availability and disaster recovery setups
- Proven experience with cloud-managed databases (e.g., AWS RDS, Aurora, DocumentDB)
- Strong SQL and NoSQL tuning skills; deep knowledge of query plans, vacuum/analyze, index strategies
- Hands-on with Liquibase, Flyway, or similar tools for version-controlled schema management
- Proficient in scripting with Python, Bash, or Go for automation
- Familiarity with AWS CLI/SDK, Terraform, or CloudFormation for database IaC
- Experience with monitoring, alerting, and performance dashboards
- Strong understanding of replication, sharding, WAL tuning, and data lifecycle management
