Software Engineer - WSSI Team (Windows Silicon System Integration)

Overview

Do you want to be part of a team building cutting-edge security solutions for Microsoft devices and silicon? Are you passionate about developing security capabilities across the stack, from embedded and firmware technologies to platform and cloud-connected services? Do you enjoy taking ideas from concept to shipped products? If so, you might be the perfect candidate for this role.

We are looking for a talented software engineer with a passion for security to help build innovative edge-to-cloud security solutions for Microsoft's next-generation devices and platforms.

You will contribute to and lead the development of core product features, from understanding system and product requirements and defining feature behavior, through architecture, design, and implementation, to delivering high-quality, secure services and endpoint components.

You will work across the stack, spanning firmware, hardware, operating systems, and cloud-connected security solutions, helping build the trusted security foundations of next-generation devices. You will collaborate with silicon partners, security experts, and engineering teams across Microsoft to deliver innovative, end-to-end security capabilities. The role offers significant technical ownership, opportunities to drive innovation, and continuous growth at every stage of your career.

AI is a core part of how we engineer. Our team has broad access to advanced AI capabilities, including unrestricted usage with no token limits, enabling engineers to fully integrate AI into their daily workflow. We actively use AI to accelerate design, coding, debugging, security research, testing, and documentation. We also empower engineers to go beyond personal productivity by building AI-powered tools and agents that improve how the entire team works and delivers value.

Join us in pushing the boundaries of security engineering. From silicon and firmware to operating systems and cloud-connected services, you'll help build trusted foundations that secure Microsoft's future devices and experiences on a global scale.
