Database Administrator

About the job

Be part of a leading global cybersecurity companyץ

What You'll Be Doing

In this role, you’ll join the growing SASE R&D DevOps group. As the Database Administrator, you will own the operational and performance aspects of the database stack and work closely with R&D engineers, SREs, and QA to ensure our data layer is resilient, efficient, secure, and scales with the business.

You will partner deeply with developers from design to production, provide input on data modeling and query optimization, and ensure best practices across the board, from schema design to observability, disaster recovery, and upgrades.

• Own and operate production and pre-production databases, including:

MongoDB (Atlas)

Redis (AWS ElastiCache Valkey)

RabbitMQ (EC2-based cluster)

• Work closely with developers to optimize data models, indexes, and queries across the SDLC (design, QA, staging, production).
• Partner with SREs to ensure high availability (99.99% uptime), disaster recovery, monitoring, and performance tuning.
• Plan and execute schema changes, index strategies, and database version upgrades with zero or minimal downtime.
• Set up and enforce backup, restore, and retention policies aligned with compliance and availability needs.
• Implement and maintain observability tools and alerting for the data infrastructure.
• Lead cost optimization of all data services — rightsizing, usage analysis, cleanup, and architecture alignment.
• Troubleshoot and resolve data-related incidents; participate in on-call rotations and post-mortems as needed.

Requirements

• At least 3 years of hands-on experience as a DBA in production-grade environments.
• Deep knowledge of MongoDB (Atlas) and Redis; experience with RabbitMQ or similar message brokers is a strong advantage.
• Experience operating databases in cloud environments (AWS preferred).
• Proficient in scripting and automation (Bash, Python, or similar).
• Experience with infrastructure as code (Terraform)- an advantage
• Familiarity with Kubernetes and container orchestration- an advantage
• Understanding of data security- an advantage
