• Zero-Downtime Maintenance: You will handle routine tasks like patching and vacuuming using blue-green update techniques to avoid service interruptions.
• Automation: You will use Ansible and Terraform to make infrastructure and deployment processes more efficient.
• Architecture & Design: You will lead the planning of our database systems and provide a clear point of view on how to design schemas for better performance.
• Performance Engineering: You will find performance problems and tune queries and indexes based on how the system is being used.
• Development Support: You will work closely with engineering teams to help them optimize queries and plan safe database migrations.
• Security & Access Management: You will manage database security, encryption, and rules for data access.
• Incident Response: You will help find the root cause of database problems and write clear documentation for our systems and recovery steps.

WHAT YOU NEED TO SUCCEED IN THIS ROLE

• PostgreSQL Expertise: You have 4+ years of hands-on experience managing production environments at a terabyte scale, such as a fleet of up to 100 instances.
• Technical Conviction: You have a proven ability to recommend and advocate for the best database setups and high-availability systems.
• Cloud Proficiency: You have experience managing databases in major cloud environments (like AWS, Azure, or GCP) or private/VPS setups. Knowledge in  Amazon Aurora, NoSQL, Columnar DBs, and/or Timeseries is a plus.
• Automation Mindset: You have a strong background in scripting and automation to manage production environments efficiently.
• AI: having the skill to use AI tools to assist with coding or monitoring is a great advantage.
