Staff Database Reliability Engineer (DBRE)

As a Staff Database Reliability Engineer (DBRE) at Demandbase, your primary responsibilities include owning the core database infrastructure, optimizing performance and uptime for our AWS RDS (PostgreSQL/MySQL), DynamoDB, and BigQuery, and architecting solutions that ensure high availability. You'll also focus on automating processes and leading a global team, driving best practices in database reliability while partnering with various engineering teams.

To be successful as a Staff Database Reliability Engineer at Demandbase, you should have at least 12 years of experience in database engineering or operations, with deep expertise in AWS RDS and DynamoDB. Strong skills in performance tuning, data security, and scripting (like Python and Shell) are essential. Experience with automation tools such as Terraform and CI/CD pipelines, along with a background in leading teams, will set you apart in your application.

Demandbase is committed to advancing the careers of its employees, including Staff Database Reliability Engineers. You will have the opportunity to mentor and lead a global team, promoting a culture of learning and shared ownership. The company encourages professional development through training, documentation, and access to a network of talented individuals working in B2B tech.

As a Staff Database Reliability Engineer at Demandbase, you will engage with a variety of tools and technologies. These include AWS RDS (PostgreSQL/MySQL), DynamoDB, BigQuery, Terraform for infrastructure as code, Python and Shell for scripting, and observability tools like Prometheus, Grafana, and Datadog to enhance database reliability and monitoring.

Demandbase provides a comprehensive benefits package for its Staff Database Reliability Engineers, including up to 100% paid premiums for medical and vision coverage, mental wellness resources, flexible PTO, and generous holiday breaks. Additionally, you can expect a competitive 401(k) plan, disability coverage, and an inclusive work environment that prioritizes diversity, equity, and inclusion.

In my previous roles, I've extensively worked with AWS RDS for both PostgreSQL and MySQL, where I implemented performance tuning strategies such as database indexing, query optimization, and connection pooling. To demonstrate this in an interview, I would share specific examples of challenges I faced, the solutions I applied, and how those actions improved the system's overall performance and reliability.

I prioritize comprehensive disaster recovery strategies that include automated backups, failover configurations, and regular testing of recovery procedures. In an interview, I would detail instances where I successfully established pertinent protocols, the tools I used to implement them, and how I ensured that the recovery time objectives were met effectively.

By adopting a defense-in-depth approach to database security, I implement role-based access controls, data encryption in transit and at rest, and regular security audits. I’d explain how I balance these layers with performance considerations and maintain accessibility without compromising on data integrity during the interview.

I have utilized tools such as Terraform and CI/CD pipelines for automating database provisioning and management tasks. In a conversation, I would provide examples of specific automation projects I've led, demonstrating the efficiency gains and error reduction achieved through these efforts.

My approach to mentoring involves providing clear direction, regular feedback, and fostering a collaborative learning environment. I would share an instance during the interview where I successfully guided junior DBREs across different time zones, enhancing their skill sets while ensuring they felt supported and valued.

My process for optimizing database queries involves analyzing execution plans, identifying bottlenecks, and making necessary adjustments, such as rewriting queries or indexing. Sharing specific examples in an interview of how I reduced query execution time will highlight my analytical and problem-solving skills effectively.

I recall a time when a major system outage occurred due to a database failure. I led the incident response, collaborating with cross-functional teams, analyzing logs, and implementing fixes. In our discussion, I'd emphasize the steps taken and lessons learned from that experience, illustrating my ability to remain calm under pressure.

I've effectively used Docker and Kubernetes to containerize database applications, manage deployments, and ensure consistency across environments. During the interview, I would dive into specific projects where my use of these technologies led to improved deployment times and streamlined operational processes.

My monitoring strategy involves using tools like Prometheus, Grafana, and Datadog for observability. In an interview, I’d share a comprehensive approach I've taken which includes setting up alerts, dashboards, and regular audits to proactively manage performance and detect anomalies in real-time.

Effective communication is essential in my role as a DBRE for collaborating with engineers and stakeholders. I’d emphasize the importance of clear documentation, regular team meetings, and transparency when addressing issues or sharing updates, and I'd provide examples of how this has fostered a collaborative work culture.
