Jobbeschreibung

Basel, Switzerland · Permanent · Hybrid

What you'd actually work on

• Designing and building open source database infrastructures (PostgreSQL, MariaDB, MySQL) for a portfolio of clients, on site or remotely

• Acting as the technical escalation point on critical performance and infrastructure issues
• Sharing what you learn through the internal knowledge base

Where it gets technically interesting

• Stateful databases on Kubernetes, where failover, storage and connection pooling all have to agree
• EDB Postgres alongside community PostgreSQL, with the tradeoffs that come with each
• Performance troubleshooting across several Linux distributions and very different client setups
• A small specialist team, so your expertise shapes how the practice works

What we're looking for

• 5+ years in database administration and infrastructure management
