[Hiring] Data Administrator (DBA) @Sleek

Role Description

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

Mission:

• Own the design, deployment, performance, availability, security, and reliability of our database fleet across PostgreSQL, AWS RDS, Aurora, MongoDB, and MariaDB.
• Work closely with engineering, data, and DevOps teams to ensure our databases are highly performant, scalable, and resilient to support business-critical workloads.

Key responsibilities:

• Administer, monitor, and maintain production database environments across PostgreSQL, AWS RDS, Aurora, MongoDB, and MariaDB.
• Design, provision, and manage highly available and fault-tolerant database architectures on AWS (RDS, Aurora clusters, Multi-AZ, read replicas).
• 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.

Qualifications

• 5+ years of hands-on experience as a Database Administrator in production environments.
• Strong understanding of database internals — storage engines, transactions, isolation levels, locking, MVCC, query planners.
• Proven experience supporting mission-critical OLTP workloads with high availability requirements.
• Solid scripting skills in Bash and/or Python for automation.
• Deep hands-on expertise with PostgreSQL administration — installation, configuration, tuning, and upgrades.
• Experience with streaming replication, logical replication, pgBouncer, and partitioning.
• Strong query tuning skills — EXPLAIN/ANALYZE, indexes (B-tree, GIN, BRIN), vacuum and bloat management.
• Hands-on experience with Aurora PostgreSQL clusters, reader/writer endpoints, and global databases.
• Strong hands-on experience operating production workloads on AWS RDS and Aurora (MySQL/PostgreSQL).
• Proficiency with parameter groups, option groups, snapshots, automated backups, and PITR.
• Experience configuring Multi-AZ, read replicas, cross-region replication, and DR setups.
• Working knowledge of AWS services around databases — IAM, KMS, Secrets Manager, VPC, Security Groups, CloudWatch, Performance Insights.
• Hands-on experience administering MongoDB (self-managed and/or Atlas).
• Replica set configuration, sharding, indexing strategies, and aggregation pipeline tuning.
• Backup, restore, and disaster recovery using mongodump/mongorestore or Ops Manager.
• Hands-on experience with MariaDB and/or MySQL administration in production.
• Experience with replication topologies (primary-replica, Galera cluster), InnoDB tuning, and binlog management.
• Familiarity with tools like mysqldump, Percona Toolkit, and ProxySQL.
• Strong experience with backup/restore strategies and validated DR procedures.
• Database security — role-based access control, encryption at rest/in transit, audit logging, and secrets rotation.
• Proficiency setting up monitoring, alerting, and dashboards for database health and performance.
• Experience leading incident response and root cause analysis for database-related outages.

Requirements

• Infrastructure as Code experience with Terraform and/or CloudFormation.
• Experience with CI/CD for database changes (Liquibase, Flyway, or schema migration tooling).
• Exposure to NoSQL/data stores beyond MongoDB (Redis, DynamoDB, Elasticsearch).
• Experience with database proxy tooling (RDS Proxy, ProxySQL, pgBouncer).
• Familiarity with containerized workloads (Docker, Kubernetes/EKS) and operating databases alongside them.
• Experience supporting SOC 2 / ISO 27001 / GDPR audits from a database perspective.
• Working knowledge of data engineering or analytics workloads (read replicas feeding warehouses, CDC via Debezium / DMS).
• AWS certifications (Solutions Architect, Database Specialty) are a plus.

Benefits

• Humility and kindness: A culture of not taking ourselves too seriously and being able to laugh.
• Flexibility: Work from home and the ability to work fully remote from anywhere in the world for 1 month each year.
• Financial benefits: Competitive market salaries, generous paid time off, and access to a flexi benefits scheme.
• Personal growth: Responsibility and autonomy with a range of internal and external training programs.
• Commitment to building Sleek as a force for good as a proudly certified B Corp.
