We are hiring a Software Engineer II to help build threat-resistant platform capabilities for Windows Server across on-premises, hybrid, and cloud-connected deployments. This is a hands-on engineering role: you will turn security architecture and threat models into shipping code, implement secure-by-design features, close systemic classes of vulnerabilities, and strengthen the platform's trust boundaries from firmware and boot through the kernel, virtualization, identity, and management surfaces.
You will work on the platform's threat-resistant capabilities and bring secure-by-design and secure-by-default ideas to reality. You will translate evolving threats, security requirements, and customer needs into working software while owning the design and implementation of well-scoped components. Experience or demonstrated interest in operating system fundamentals and/or software and system security is a plus; experience with confidential computing or secure use of cryptography is valued.
