The posting

About the Role: We are looking for a Senior Database Administrator (DBA) to design, implement, and maintain database environments across multiple platforms, including AWS Redshift, Microsoft SQL Server (MSSQL), PostgreSQL, and Oracle. The ideal candidate is a hands-on database expert who ensures the performance, availability, security, and integrity of business-critical data systems, while mentoring junior team members and driving best practices across the organization.

Responsibilities:

  • Administer, configure, and maintain database systems across AWS Redshift, MSSQL, PostgreSQL, and Oracle environments, ensuring high availability and optimal performance.
  • Monitor database performance, proactively identify bottlenecks, and implement tuning strategies including query optimization, indexing, and partitioning.
  • Lead capacity planning and scalability initiatives, including cloud resource optimization for AWS Redshift environments.
  • Design and implement backup, recovery, and disaster recovery strategies to safeguard data integrity and minimize downtime.
  • Plan and execute database upgrades, patches, and migrations with minimal disruption to production systems.
  • Troubleshoot and resolve complex database incidents, performing root cause analysis and implementing preventive measures.
  • Manage database security, including user access controls, roles, encryption, and compliance with data governance and regulatory requirements.
  • Establish and enforce database standards, policies, and best practices across the organization.
  • Develop and maintain documentation for database architecture, configurations, standard operating procedures, and runbooks.
  • Automate routine database administration tasks using scripting languages (e.g., Python, Bash, PowerShell) and infrastructure-as-code tools.
  • Mentor and provide technical guidance to junior DBAs.
  • Participate in an on-call rotation to support critical production systems.

Requirements:

  • Bachelor's degree in Computer Science, Information Systems, or a related field, or equivalent hands-on experience.
  • 5 years of progressive DBA experience, including hands-on administration of at least two of the following: AWS Redshift, MSSQL, PostgreSQL, Oracle.
  • Proven experience designing and executing backup, recovery, and disaster recovery strategies in production environments.
  • Strong grounding in performance tuning: query optimization, indexing strategy, partitioning, and capacity planning.
  • Working knowledge of database security practices — access control, roles, encryption at rest/in transit, and audit/compliance requirements.
  • Scripting proficiency in Python, Bash, or PowerShell, with experience automating routine DBA tasks; familiarity with infrastructure-as-code tools (e.g., Terraform, CloudFormation) is a plus.
  • Relevant certifications preferred (e.g., AWS Certified Database - Specialty, Oracle OCP, Microsoft Certified: Azure Database Administrator Associate).
  • Experience mentoring junior engineers and leading technical best-practice initiatives.
  • Strong written communication skills for documentation, SOPs, and runbooks.
  • Comfortable participating in an on-call rotation.

Nice to Have:

  • Experience operating in regulated or public-sector environments with strict data governance and compliance requirements.
  • Exposure to multi-account/multi-tenant cloud environments.
  • Prior experience leading migrations or major version upgrades with minimal production disruption.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
