NOTE: Job posting may be removed earlier if the position is filled or if a sufficient number of applications are received.  

Meet the Team

Join Cisco's Network Device Security Organization to help protect more than 50 million live network devices! Our portfolio includes routers, switches, access points, wireless LAN controllers, campus gateways, industrial IoT devices, cameras, and sensors. These products help power the world's internet, from autonomous on-premises systems to cloud-managed networks. We bring engineers together to turn security research into practical protections that customers can trust. Work across hardware, firmware, and software, with opportunities to learn, share ideas, and expand security delivery through AI.

Your Impact

Help shape how Cisco designs, reviews, and verifies security across its network device portfolio. Create threat models and review device architectures and code to find weaknesses at their root. Translate recurring weakness classes into secure patterns and reusable engineering controls. Test security claims after implementation, using reproducible evidence to show what works and where gaps remain. Collaborate with engineers across functions, cultures, and geographies in an organization spanning thousands of people, using AI-enabled workflows to improve security delivery.

Minimum Qualifications

• A bachelor's degree in computer science, engineering, or a related technical field with 7 years of related experience; a master's with 4 years; or a PhD with 1 year, preferably complemented by CSSLP certification.
• Experience delivering threat models, security reviews, and reusable controls or patterns, with test cases and reproducible evidence that verify implemented behavior.
• Experience assessing and improving the security of embedded or IoT network devices across hardware, firmware, and the device lifecycle, including C/C++ code review, device security testing, and security tooling in Python or a comparable language.
• Experience using CWE hardware and software weakness hierarchies to identify root causes and recurring patterns, and applying MITRE EMB3D, OWASP IoT guidance, or comparable device-security frameworks to threat modeling and remediation.

Preferred Qualifications

• Experience collaborating with engineers across functions, cultures, and geographies in large matrix organizations through clear communication of security findings and technical tradeoffs, mentoring, and coordinated delivery.
• Experience applying systems thinking and risk exposure to prioritize security work, align claims with evidence, and guide escalations that support high-quality delivery and customer outcomes.
• Experience building agentic workflows that integrate models, tools, and engineering data, with evaluations, human review, protected inputs, and improvements as model capabilities change.
• Experience developing static-analysis rules, secure APIs or wrappers, or CI/CD guardrails, and evaluating their precision, coverage, and adoption across multiple repositories or product families.
