Listing Description

Mozilla’s ITEO Security Engineering Team is looking for an experienced Security Engineer to help drive key programs as we continue to modernize and scale our environment. You will have direct responsibility for engineering systems in areas such as vulnerability management, IAM/PAM, and related infrastructure. You will also be involved in all other aspects of our SecEng team’s duties.

You will be hardening and guiding recommendations for Mozilla’s systems and networks, infrastructure, application security services, and company assets, while ensuring the mission of privacy and security is upheld at all times. This is a hands-on role, however you will work with many teams to guide proper security practices throughout the company as well.

As a Staff Security Engineer at Mozilla, you will…

• Design, build and deploy vulnerability management frameworks and technologies across Mozilla Corporation


• Work with the Risk Assurance team to ensure that our policies and governance are well written and achievable


• Review and improve IAM systems across MoCo. This will include new designs and implementation, as well as ensuring other teams are successfully integrated


• Design, review and improve the security controls of the organization alongside other SecEng engineers


• Write, maintain, and expand automation scripts and monitoring tools


• Protect the services which Mozilla Corporation and our products like Firefox and others depend on from attacks and abuses


• Work with developers and operations teams across the organization to keep the Firefox backend infrastructure safe

Your Professional Profile

This role will likely involve some development work as we build and improve our security tools and automation. You should be proficient in Python, and Go is a definite plus as well. You should also feel comfortable running cloud infrastructure for the code you write and documenting your applications for other ops teams to run with.  Additional skills include:

• Strong infrastructure and application security knowledge, including popular web stacks, SaaS platforms, AppSec concepts, and security methodologies


• A thorough understanding of vulnerability management beyond scanning tools. Vuln Management Program experience is key, along with creative thinking on how vulns exist and come to be - especially in a software development / DevSecOps environment such as ours


• You know how modern IAM and PAM are designed and implemented, especially in mixed public cloud environments and SaaS integrations


• A B.S. in Computer Science is fantastic, but real-world experience is preferred
