Security Engineer (Builder)

To help Meta secure its millions of technology assets, we're seeking a Security Engineer with software development skills to help us build and improve a system that measures the security risk of different assets around the world. This system, called Security Impact Rating (SIR), helps prioritize security efforts by identifying which assets pose the greatest potential risk. If building scalable security solutions to help protect the data of billions of users sounds exciting, this might be the role for you.

Security Engineer (Builder) Responsibilities:

• Rank different types of technology assets based on their security risks
• Identify and collect security signals (data points) that indicate the risk level of each asset
• Design algorithms that calculate a security risk score for assets based on these signals and their relationships
• Create code to implement these algorithms and integrate them into the company's security infrastructure
• Validate and test the accuracy of the risk scores through manual review and automated testing
• Collaborate with other engineers, security analysts, and stakeholders to review designs, share progress, and communicate results
• Monitor the system after launch to ensure it continues to provide accurate and useful risk ratings, and make improvements as needed
• Author clear technical documentation

Minimum Qualifications:

• B.S. or M.S. in Computer Science or related field, or equivalent experience
• 2+ years of experience in designing and implementing security systems, tools, or frameworks
• Demonstrated programming skills in languages commonly used for backend development (e.g., PHP, Python, SQL)
• Experience designing and implementing algorithms that process complex data
• Familiarity with security fundamentals such as access control, data sensitivity, data classification methodology, and risk assessment
• Problem-solving skills and attention to detail
• Extensive knowledge of attacker tactics, techniques, and procedures
• Proficiency in coding with experience in languages such as Python, C/C++, Go, or equivalent
• Experience collaborating with technical and non-technical stakeholders
• Ability to rapidly prototype and iterate on security solutions

Preferred Qualifications:

• Experience coding and debugging with AI-assisted tools
• Experience with AI prompt engineering
