We’re looking for a Software Engineer III (Database Engineer) to own the reliability, performance, and scalability of our production database systems. This role focuses on high-availability OLTP environments and ensures safe, efficient integration with downstream data systems. You will work across MySQL, PostgreSQL, and DynamoDB systems, supporting replication strategies, ELT/ETL pipelines, and streaming integrations. This role partners closely with backend, data, and infrastructure teams to protect transactional systems while enabling scalable data movement across the organization. This position requires strong ownership, attention to detail, and the ability to balance performance, cost, and data integrity in production environments.

Job Responsibility

  • Operate and optimize production database systems including MySQL, PostgreSQL, DynamoDB, and Elastic
  • Design and manage binlog and logical replication strategies
  • Support ELT/ETL pipelines and CDC workflows to ensure safe data movement
  • Integrate transactional systems with Kafka-based streaming architectures
  • Optimize database performance through query tuning, indexing, and scaling strategies
  • Manage backups, failover processes, and disaster recovery (PITR)
  • Monitor system health and drive infrastructure cost efficiency
  • Enforce data integrity, security, and compliance standards
  • Lead and support database-related incident response

Requirements

  • 5+ years of database engineering experience in production environments
  • Deep hands-on experience with MySQL and/or PostgreSQL
  • Experience owning and supporting high-availability OLTP systems
  • Experience with binlog or logical replication
  • Experience integrating OLTP systems with Kafka or similar streaming platforms
  • Experience supporting ELT/ETL pipelines and data workflows
  • Strong understanding of ACID principles and transaction isolation levels
  • Experience troubleshooting performance issues (locking, replication lag, indexing)
  • Familiarity with AWS-managed database services (RDS, Aurora, DynamoDB)
  • Ability to balance performance, cost, and data integrity in production systems

Nice to have

  • Experience implementing CDC workflows
  • Experience with large-scale database migrations
  • Understanding of OLTP vs OLAP workload separation
  • Experience with infrastructure-as-code tools such as Terraform
  • Background in high-volume, transaction-intensive environments
