Principal Database Reliability Engineer (DBRE)

We are looking for a Principal Database Reliability Engineer (DBRE) to take extreme ownership of our critical database infrastructure. Working within our Technical Operations team, you will act as the definitive Subject Matter Expert for our highly available MySQL and PostgreSQL estates, operating with a high degree of autonomy to design, build, and optimise our data tier. This is a high‑impact role where you will predominantly lead the database strategy, bridging the gap between traditional database administration and modern Site Reliability Engineering (SRE). You will architect resilient data systems, automate toil through Infrastructure as Code, manage our event‑streaming platforms (Kafka), and empower our wider engineering teams with database best practices. If you're excited by the challenge of owning a complex data estate and defining its future state, this is the role for you.

As a Principal DBRE at Partnerize, You Will:

• Own the Data Estate: Serve as the primary architect and technical lead for our highly available, distributed MySQL and PostgreSQL environments.
• Automate Everything: Transition manual database management into code. Build, maintain, and optimise deployment pipelines for infrastructure using Terraform, Ansible, and Python.
• Architect for Scale: Lead capacity planning, disaster recovery design, and high‑availability architecture for both bare‑metal and containerised data systems.
• Manage Event Streaming: Oversee and scale our data streaming and queuing technologies (Kafka, RabbitMQ) to support event‑driven microservices.
• Drive Performance: Proactively monitor, troubleshoot, and optimise database performance, advising development teams on query tuning, schema design, and technical debt refactoring.
• Empower the Team: Mentor wider TechOps and Engineering teams on data infrastructure best practices, creating cohesive documentation and building guardrails so the broader team can safely support the data tier.
• Lead Incident Response: Act as the ultimate escalation point for complex database incidents, leading Root Cause Analysis (RCAs) and implementing permanent fixes.
• Participate in On‑Call: Share in the rotational on‑call duties, with a specific focus on ensuring the database tier remains robust and self‑healing to minimise after‑hours alerts.

Essential Knowledge, Skills and Experience

• 8+ years of experience in Senior DBA, DBRE, or deeply data‑focused SRE roles managing large‑scale, production systems.
• Expert‑level relational database knowledge: Deep, hands‑on experience designing, scaling, and maintaining HA environments in MySQL and PostgreSQL, including replication, clustering, and backup/restore strategies.
• Infrastructure as Code & Automation: Strong proficiency in Python or Bash scripting, combined with configuration management and IaC tools (Ansible, Terraform, Helm).
• Modern Infrastructure: Solid understanding of deploying and managing services within containerised environments (Kubernetes, Docker) and navigating modern event‑driven architectures (Apache Kafka).
• Linux Mastery: Advanced experience configuring, tuning, and monitoring Linux systems in physical data centres and cloud environments.
• Observability: Experience building out robust monitoring and alerting for data systems to proactively catch bottlenecks.
• Leadership & Autonomy: Proven ability to operate independently, prioritise workloads, and lead major technical projects from design to production.

Desirable Knowledge, Skills and Experience

• Experience migrating bare‑metal database infrastructure into private or public cloud environments.
• Experience with specific monitoring systems such as Prometheus, Zabbix, or Datadog.
• Familiarity with in‑memory data stores (Redis) and analytic databases (Druid).
• Experience with Elasticsearch and Kibana for logging and search.
• Knowledge of HAProxy, Nginx, or Gluster storage technologies.
