Principal SDET - Performance Testing for Bare-Metal Cloud

Akamai; United States; Hybride; USD 169 000 - 305 000; Plein temps

Résumé du poste

Akamai is seeking a Principal Software Development Engineer in Test to lead test strategy for hypervisor behavior and VM performance across the IaaS platform. You will design reproducible environments using containers to emulate bare-metal VM conditions and collaborate with product and SRE to define SLOs and safe deployment practices.

You will write test harnesses in Go, Python, and Perl, mentor SDETs, and drive CI/CD quality gates with performance benchmarks and robust data analysis.

Qualifications

• 12 years in testing, including performance testing and systems-level testing.
• Experience in KVM/QEMU/libvirt internals, VM-exits, and NUMA/cache effects on performance.
• Experience debugging across architectures (x86, ARM) on bare metal and emulated environments.
• Strong Linux fundamentals: scheduler, memory management, I/O subsystems, storage architectures, and block devices.
• Demonstrate statistical thinking: experimental design, baseline analysis, variance control, and stakeholder communication.
• Proficiency with Linux perf, VTune, eBPF, Bash, Jenkins, and SaltStack.

Responsabilités

• Define and own test strategy for hypervisor behavior, VM performance, and fleet-level quality gates; mentoring SDETs on statistical rigor and systems-level testing.
• Design reproducible test environments that emulate bare-metal VM conditions using containers, validating data integrity, without requiring physical hardware.
• Develop automated performance benchmarks with statistical baselines, change-point detection, and regression gating for CI/CD pipelines.
• Collaborating with product and SRE to define SLO measurement and validate deployment safety and rollback strategies.
• Writing test harnesses and performance analysis pipelines in Go, Python, and Perl.
