## Description

Do you want to help design and implement the next generation of cloud computing?, Our team's mission is to accelerate innovation by making computing simple, scalable, accessible, and affordable for all. We provide the infrastructure and services that enable developers to build next-generation applications. We take ownership of the design and development of core compute interfaces, virtualization management, APIs, and low-level platform services., As a Principal Software Development Engineer in Test, you will own VM/fleet test strategy, performance quality gates, and hypervisor behavior validation across the IaaS platform.

As a Principal Software Development Engineer in Test, you will be responsible for:

 * Defining and owning test strategy for hypervisor behavior, VM performance, and fleet-level quality gates; mentoring SDETs on statistical rigor and systems-level testing.
 * Designing reproducible test environments that emulate bare-metal VM conditions using containers, validating data integrity, without requiring physical hardware.
 * Developing 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.
