Site Reliability Engineer III (DBA)

About Backblaze

Backblaze is the object storage leader in the open cloud movement, fueling customer success with cloud storage built purposefully to unlock budgets, unburden administrators, and unleash innovators. Together with our partners, we’re helping customers break free from the restrictive, overpriced legacy solutions that hold them back, and blaze forward with the full power of the open cloud in their hands.

Founded in 2007, we scaled the business with less than $3 million in outside funding until 2021, when we did a traditional IPO on the Nasdaq stock exchange. Today, Backblaze generates over $100m in revenue and is the leading specialized storage cloud - managing over three billion gigabytes of data storage for 500K+ customers in 175+ countries, including businesses, developers, IT professionals, and individuals.

But while there is a lot to celebrate in our past, there is almost as much opportunity ahead of us. We’re seeking a Site Reliability Engineer III (DBA) to join our team!

About the Role:

Individuals fulfilling this role will be responsible for ensuring the stability, scalability, and reliability of our production database systems, primarily Vitess (distributed MySQL) and Cassandra, alongside the rest of our production services and infrastructure. This role carries the same on-call, incident response, and service ownership expectations as other SRE IIIs, with database systems serving as the area of deepest technical ownership.

Because our SRE Database Engineering function is new, this role will also help establish its operational foundation by designing database architecture and developing the runbooks, escalation guidance, procedures, and training materials that our Level 1 and Level 2 SRE Database Engineers will use as they onboard. The ideal candidate will have strong experience with production database systems, Linux, automation, distributed systems, Kubernetes, observability, and incident response, with a proactive approach to reliability and operational excellence.

What You'll Do:

Database Architecture & Administration:

Design, deploy, and own highly available database architecture for Vitess (distributed MySQL) and Cassandra

Establish and document operational procedures, runbooks, and escalation guidance for Level 1 and Level 2 SRE Database Engineers

Optimize database performance through query tuning, indexing strategies, schema design, and capacity planning

Own database backup, recovery, replication, and disaster recovery strategies

Perform and validate disaster recovery testing and database recovery procedures

Drive database security, access control, patching, hardening, and compliance practices

Partner with the DBA and Data Infrastructure teams on resharding, capacity planning, replication, and architecture decisions for sharded MySQL environments

Service Reliability & Operations:

Support the availability and durability of critical services across production environments

Monitor service health using SLIs, SLOs, error budgets, monitoring, logging, and alerting platforms

Partner with service owners to define and improve SLIs, SLOs, error budget policies, and alerting

Participate in on-call rotations, incident response, root cause analysis, and post-incident reviews

Serve as an escalation point for complex database production incidents

Follow established ITIL/OSS processes including incident, change, problem, and capacity management

Take ownership of operational issues and drive projects from problem discovery through resolution

Automation & Tooling:

Develop automation for common operational and database administration tasks to reduce manual intervention and operational toil

Contribute to monitoring, logging, and alerting frameworks including Prometheus, Grafana, Catchpoint, and ELK

Help integrate operational runbooks and incident response workflows with FireHydrant

Work with CI/CD pipelines, configuration management, and infrastructure as code tools including Terraform, Ansible, and Jenkins

Develop scripts using Bash, Python, Go, or similar technologies to improve reliability and operational efficiency

Operate and troubleshoot containerized production environments using Kubernetes and Docker

Work within Kubernetes and Vitess environments using technologies such as kubectl, mysqlsh, and Vitess keyspaces

Project Management:

Lead Production Readiness Reviews (PRRs) for functionality being handed off from engineering partner teams

Support the operational readiness of new database-backed services before they enter production

Build training plans, onboarding materials, and technical documentation for new Level 1 and Level 2 SRE Database Engineers

Partner with Engineering, Product, Operations, and DBA/Data Infrastructure teams on reliability initiatives

Assist with capacity planning, disaster recovery exercises, database migrations, and infrastructure projects

Work with vendors and service providers to troubleshoot service issues and track SLA performance

Identify opportunities for automation and process efficiency

Incident response

Respond to and resolve production database, infrastructure, and service incidents

Troubleshoot and escalate database, Linux, networking, application, and infrastructure issues as needed

Participate in the on-call rotation and serve as an escalation point for database-related incidents

Lead or contribute to root cause analysis and post-incident reviews

Identify recurring issues and develop long-term corrective actions to improve reliability

What we value:

A proactive mindset with a can-do attitude

Someone who can work independently, take ownership, and drive complex technical problems through resolution

Someone who steps up, supports teammates, mentors others, and shares knowledge freely

Strong problem-solving skills and a willingness to learn new technologies

Curiosity, reliability, and a desire to improve the reliability and scalability of production systems

Required Qualifications:

6–8 years of experience in site reliability engineering, systems engineering, infrastructure operations, database engineering, or similar roles, with meaningful experience supporting production database systems.

Deep hands-on experience with MySQL and distributed or sharded database systems.

Experience with Vitess in a production environment strongly preferred.

Experience administering and supporting NoSQL databases such as Cassandra.

Experience designing high-availability database architecture, replication topology, backup strategies, and disaster recovery processes.

Strong SQL skills, including query performance analysis, indexing, schema design, and troubleshooting.

Solid Linux systems administration and troubleshooting skills.

Experience with security-focused operations including patching, system hardening, access controls, and vulnerability remediation.

Strong understanding of service reliability concepts including monitoring, alerting, incident response, root cause analysis, SLIs, SLOs, and error budgets.

Experience working with containers and orchestration platforms including Kubernetes and Docker.

Comfortable operating in Kubernetes and Vitess environments using tools such as kubectl, mysqlsh, and Vitess keyspaces.

Experience with infrastructure and configuration management technologies including Terraform, Ansible, Jenkins, and HashiCorp products such as Vault and Nomad.

Proficiency in at least one scripting language such as Python, Bash, or Go.

Experience establishing operational procedures, runbooks, documentation, and escalation processes.

Experience mentoring, training, or helping onboard engineers into complex technical environments.

Experience in SaaS, cloud services, service provider, or large-scale distributed systems environments preferred.

Experience with AWS, GCP, Azure, or similar cloud platforms prefer
