We're looking for a Senior Database Administrator — someone who has spent the core of their career as a traditional DBA and has evolved into a cloud-native, automation-first operator.

This is a high-ownership & autonomous role: you'll be solely responsible for database architecture, reliability, and data safety across the organization, primarily on MySQL in AWS, with potential migration to PostgreSQL.

Responsibilities

Act as the senior technical authority on database architecture, reliability, performance, and data integrity across the organization
Own end-to-end administration of production MySQL (potentially PostgreSQL) fleets: replication topology, backup/recovery, upgrades, capacity planning, and performance tuning
Design and evolve highly available AWS database architectures (RDS/Aurora Multi-AZ, cross-region replicas, failover strategies) with a bias toward resilience and simplicity
Own backup and disaster recovery strategy end-to-end — design, automation, regular restore testing, and RTO/RPO documentation — and be accountable for data recoverability
Lead complex database migrations (major version upgrades, engine changes, cloud migrations, large schema changes) with minimal to zero downtime
Define the observability strategy for databases: build and maintain dashboards, custom metrics, and alerting in Datadog and Coralogix; set meaningful SLOs/SLIs
Drive deep root-cause analysis on production database incidents, lead postmortems, and turn findings into durable fixes and runbooks
Perform advanced query and index optimization, execution plan analysis, and proactive tuning at scale
Set and enforce standards for schema design, data access patterns, and query review; act as a senior reviewer/gatekeeper for schema changes
Drive automation of DBA workflows (provisioning, patching, failover drills, backup validation) using Terraform and scripting
Own database security posture: encryption, IAM/least-privilege, credential rotation, audit logging, and compliance support (SOC 2, GDPR, etc.)
Mentor other engineers on database best practices; be a go-to escalation point for the hardest database problems
Participate in and help shape the on-call rotation for database incidents
Influence technology choices and long-term data architecture strategy in partnership with engineering leadership

Requirements

7+ years of hands-on DBA experience with demonstrable depth in database internals
Deep, expert-level administration experience with MySQL — replication (async/semi-sync/group replication), backup/recovery internals, InnoDB internals, performance tuning, troubleshooting complex production issues
Several years running databases in AWS, including RDS/Aurora Multi-AZ, failover mechanics, read replicas, and cost/performance trade-offs between managed and self-hosted options
Proven track record owning backup and DR strategy, including designing and executing real disaster recovery tests
Track record leading major database migrations (version upgrades, engine/platform migrations, cloud migrations) with minimal downtime, including rollback planning
Strong hands-on experience with monitoring/observability tooling (Datadog, Coralogix, CloudWatch, or equivalent) — designing metrics and alerting strategy
Expert SQL skills: query optimization, indexing strategy, execution plan analysis at scale
Scripting/automation skills (Python, Bash) and Infrastructure as Code (Terraform)
Solid grasp of networking, security groups, IAM, and encryption as they apply to databases
Demonstrated experience owning incidents end-to-end: detection, mitigation, RCA, and prevention
Strong communication skills — able to explain database risk and trade-offs to both engineers and leadership

Benefits

24 vacation days annually
6 sick days without medical certificate
Premium Health Insurance
Relocation package for international candidates
