principal Software engineer

Azure Chaos Studio is one of the core products our team builds, an engineering platform that enables controlled experimentation and fault injection across Azure and Microsoft’s cloud infrastructure. With Azure Chaos Studio, engineers can intentionally introduce real‑world failure conditions such as network latency, resource throttling, and service outages. These controlled experiments help teams validate system resilience, uncover hidden issues before they impact customers, and strengthen the reliability and availability of cloud services at scale. By driving a disciplined approach to chaos engineering, our team empowers product teams across Microsoft to build more robust and dependable systems.
