Operations Security Engineer

Overview

Mozilla’s Firefox Operations Security Team is looking for a Security Engineer to increase the security of our physical and cloud infrastructure. You will need experience monitoring web services for fraud and abuse, familiarity with incident response protocols, and a good understanding of DevOps and modern web applications. You will be hardening our systems and networks, and integrating security monitoring in our existing infrastructure, both in datacenters and AWS. You will be providing hands-on technical engineering of our ever-growing server and application environments.

Most importantly, you will become a core member of the team responsible for protecting Firefox, and keeping Mozilla’s users safe on the Internet.

As an operations security engineer at Mozilla, you will…

• Protect the services Firefox depends on from attacks and abuses.
• Design, build and deploy security controls such as log monitoring, fraud detection, network filtering, intrusion detection, system call auditing, etc.
• Review and improve the security controls of the organization
• Write, maintain, and expand automation scripts and monitoring tools
• Work with developers and operations across the organization to keep the Firefox backend infrastructure safe

Your Professional Profile

• You have proven infrastructure security knowledge, from high level architectural concepts down to the implementation.
• You have a real passion for beautiful code, and successfully completed projects in C, Python, Ruby, or Go.
• You have worked with log aggregation and log analysis techniques, and are familiar with the concepts of SIEM technology.
• The full stack does not scare you, and you are comfortable running the infrastructure for the code you write.
• Optionally, you spent some time with AWS, Heroku, GCP or Azure. Maybe you’ve even written a Lambda function or two.
• A B.S. in Computer Science would be lovely, but real-world experience is preferred.
