  • Support infrastructure modernisation projects, including cloud adoption and optimisation initiatives
  • Ensure database security, compliance, and governance through controls such as encryption, auditing, and access management 
  • Create and maintain technical documentation, runbooks, and operational standards
  • Provide technical mentorship and guidance to junior database administrators
  • Participate in critical incident response and provide after‑hours support when required

  • A relevant degree in Information Technology, Computer Science, or a related discipline
  • Strong expertise in SQL Server or similar relational database management systems
  • Proven experience with high availability, disaster recovery, and replication technologies
  • Advanced skills in database performance tuning and query optimisation 
  • Experience with automation and scripting (e.g. PowerShell, Bash, or Python) 
  • Experience with Clickhouse DB or Foundation DB or LGTM Stack (Loki, Grafana, Tempo, Mimir) or Rybbit or Valkey
  • Exposure to cloud platforms and modern infrastructure environments 
  • Solid understanding of security, compliance, and data governance practices 
  • Strong problem‑solving skills and the ability to manage critical incidents independently
  • Excellent communication skills with the ability to work across technical and business stakeholders
  • A collaborative team player who values knowledge sharing and continuous improvement


Why Join Us?


  • Play a critical role in maintaining and optimising enterprise‑scale database platforms
