About the team:
Our Site Reliability Engineering team builds and maintains the Luno platform, supports development teams and manages data infrastructure. Our platform is accessed by over 10 million customers in nearly 50 countries.
The SRE team collaborates with our engineering teams to build tools and scalable shared infrastructure that is the backbone of the Luno platform.
We champion reliability, observability, automation and consistency throughout the engineering organisation.
Data is the lifeblood of our platform and as such the reliability, security and performance of our data platform is mission critical.
We’re agile, use scrum, continuous integration and continuous delivery, deploying to production every single day.
Your mission will be:
Design, implement, and maintain high-availability database clusters using technologies such as Aurora MySQL / PostgreSQL ensuring 99.99% uptime across production environments
Architect and manage robust data replication strategies, implementing both synchronous and asynchronous replication solutions while maintaining data consistency and integrity across multiple data centers
Drive cost optimization initiatives through capacity planning, resource utilization analysis, and implementation of efficient storage strategies, resulting in measurable infrastructure savings
Monitor and tune database performance using advanced diagnostic tools, query optimization techniques, and performance metrics to maintain response times within SLA requirements
Design and execute comprehensive disaster recovery testing programs, including regular failover drills and recovery time objective (RTO) validation
Develop and maintain automated backup solutions with point-in-time recovery capabilities while ensuring compliance with data retention policies and regulatory requirements
Implement robust security measures including encryption at rest and in transit, audit logging, and role-based access control (RBAC) aligned with zero-trust security principles
Collaborate with development teams to optimize database design, improve query performance, and provide data modeling expertise
A little about you:
Friendly, transparent, articulate and driven to succeed.
Good skills and knowledge of collaborative leadership, facilitation, situational awareness, conflict resolution, empowerment, and increasing transparency.
Track record of solving complex scaling problems with a focus on reliability and security.
Track record designing and implementing innovative solutions that improve operational efficiency and minimise toil.
A diverse toolkit of techniques to help drive continuous improvement i.e. contribution to the open-source community, training and certifications, regular attendance at conferences and meetups where you continue to advance your data engineering skills and techniques.
It’s completely OK if you don’t tick all of the boxes – they’re a guide based on what we’d love to see, but we appreciate that excellent engineering leaders have diverse backgrounds.
