Nature of work · Performance Engineering / Production Support
Build and support Java applications with a strong focus on performance, scalability, SLA governance, and production incident resolution, while also driving performance testing, tuning, and RCA with monitoring tools.
"• Manage governance of performance to SLAs and ensure all systems are operating within the defined SLAs."
Tech stack maturity
Mainstream Modern
A Performance Engineer role with Java as the primary skill typically aligns with well-established, widely adopted enterprise tooling and practices rather than legacy-only or bleeding-edge stacks.
