• Solid working knowledge of PostgreSQL in production, including query plans, indexing and safe online migrations.
• Incident response experience, calm under pressure and structured debugging.
• Genuine interest in databases and growing PostgreSQL/DBA expertise.

Required skills

• Working knowledge of PostgreSQL and Linux at the operator level.
• Cloud networking fundamentals (VPCs, routing, load balancing, DNS, TLS).
• Modern observability stack and a modern language such as Go or Python.
• Nice to have: production messaging systems (RabbitMQ, Kafka, Redpanda), typed SQL access layers in Go, SOC 2 and regulated fintech experience.

What we offer

• Competitive salary and stock options.
• Health benefits.
• New hire home-office setup of USD 500 and a monthly USD 150 stipend via a Brex card.
