We are looking for an experienced and hands-on Database Administrator (DBA) to join our growing Platform Engineering team.

Mission:

You will own the design, deployment, performance, availability, security, and reliability of our database fleet across PostgreSQL, AWS RDS, Aurora, MongoDB, and MariaDB.

• Perform installation, configuration, upgrades, patching, and version migrations of database engines.
• Plan and execute database migrations (on-prem to cloud, cross-engine, version upgrades) with minimal downtime.
• Implement and manage backup, restore, point-in-time recovery (PITR), and disaster recovery (DR) strategies; regularly validate recovery drills.
• Tune database performance — query optimization, indexing strategies, execution plan analysis, vacuum/auto-vacuum tuning, and connection pooling.
• Capacity planning, sizing, and cost optimization for AWS RDS / Aurora workloads.
• Set up replication (logical/physical, streaming, MongoDB replica sets, MariaDB Galera/primary-replica) and manage failover.
• Define and enforce database security best practices — user access, IAM authentication, encryption at rest and in transit, KMS, secrets management, audit logging.
• Build robust monitoring, alerting, and observability for databases using CloudWatch, Performance Insights, Prometheus/Grafana, or similar tooling.
• Troubleshoot production incidents — slow queries, locks, replication lag, storage saturation — and drive RCA and permanent fixes.
• Automate routine DBA operations using scripts (Bash, Python) and Infrastructure as Code (Terraform/CloudFormation).
• Partner with developers on schema design, data modeling, query reviews, and database best practices.
• Maintain documentation, runbooks, and standard operating procedures for the database platform.
• Support compliance requirements (SOC 2, ISO 27001, GDPR) for database systems.

• Hands-on experience with Aurora PostgreSQL clusters, reader/writer endpoints, and global databases.

Nice to have:

• Infrastructure as Code experience with Terraform and/or CloudFormation.

Behavioural fit is also important at Sleek, and we will be looking for candidates that have a proven track record of embodying the below attributes in their recent roles:

Ownership: This shows reliability and helps build trust within the team. We move fast and need to know that everyone will see things through to completion and proactively help to get things back on track when challenges arise. Accountability is really important to us.

H umility: There is so much we don’t know. Humility allows for open-mindedness to feedback and a willingness to learn from others. It paves the way for collaboration and creates a positive work environment. It is a key ingredient of self awareness and emotional intelligence.

Structured Thinking: Our business is complex with many layers (many services, many countries, many cultures). Regardless of whether you’re more analytical or creative in nature, being able to show sound judgement is important to us. It ensures solutions are pragmatic and balance the needs of the organisation, team and customers.

Data driven: We are a data rich business with ~15,000 small customers.  Each decision we make can impact many more people than we realise - so it’s critical that we use sound data to support our strategies and review the success of our initiatives.

Can have tough conversations in a positive wa y: It’s not a matter of if, but when difficult interpersonal situations arise.  Disagreement, conflict and disappointment are a given in a fast moving business where people care about their work.  People that proactively have tough conversations with kindness build empathy, trust and great working relationships.
