Principal Software Engineer

What you'll do

• Set the technical strategy and architecture for AEGIS’s security platforms and AI agentic systems over 12–24 months.
• Provide deep architectural reviews across IC3 security work to ensure high standards without becoming a bottleneck.
• Define and enforce quality gates that make consistent security execution default practice across IC3 services.
• Exercise compliance judgment by translating regulatory frameworks into concrete engineering requirements and automation.
• Drive partner alignment with security architects, MSRC, privacy, compliance, and service-owner leadership to advance SFI as one program.
• Apply AI/ML rigorously to reduce false positives and prioritize high-risk findings in agentic systems.
• Own production posture and lead Sev 1/2 post-incident reviews to ensure durable engineering improvements.

What we're looking for

• 6+ years of experience in designing, shipping, and operating large-scale cloud services.
• Demonstrated expertise in security engineering with a focus on secure design, threat modeling, and vulnerability management.
• Proficiency in modern programming languages like C#, Python, Go, or Java, with production code experience.
• Track record of technical leadership without formal authority, influencing peer principals and architects.
• Experience applying AI/ML to solve engineering or security problems, including evaluation and safety design.
• Deep knowledge of cloud-native security controls at scale and ability to encode compliance frameworks into automation.
