Join our team as a DBA Architect and play a key role in shaping the future of our client's platform. As part of a cross-functional development team, your work will directly impact scaling the platform to handle heavy loads and achieve global reach.

  • Scaling: Architect and aid in transforming our current clusters to highly available large-cluster cloud deployments to meet our scaling needs
  • Coaching & Mentorship: Coach and mentor developers on database best practices, query optimisation techniques, and the effective use of MySQL features
  • Backup & Recovery: Design and implement robust backup and recovery strategies, ensuring data integrity and availability in the event of system failures
  • Security Management: Ensure that the databases are secure, with appropriate access controls, encryption, and auditing in place to protect sensitive data
  • Documentation: Maintain documentation of database architectures, processes, and best practices to ensure knowledge sharing and continuity within the team

Requirements

  • Solid knowledge of the ins and outs of writing SQL-queries in PHP applications
  • Good track record of architecting and deploying different types of database infrastructures in a cloud-based environment
  • Experience with infrastructure as code tools and frameworks such as for example Ansible and Terraform would be a pré
