• Identifying bottlenecks, tuning infrastructure, and enabling high availability
• Advising senior stakeholders on system health and performance risks

You’ll need to bring:

• 5+ years in a lead or principal role within quality engineering
• Strong hands-on expertise with platforms: JMeter, BlazeMeter and Cloudflare, etc.
• Proven experience testing APIs, web applications, and databases: i.e PostgreSQL, Oracle and MSSQL.
