## Description

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.

Partner with the best

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.
