Mozilla’s ITEO Security Engineering Team is looking for an experienced Security Engineer to increase the security of our systems and applications. You will have a strong background securing applications and resources in GCP and AWS, understand data security and encryption methodologies, be able to create reusable architectural patterns, and be able to lead technical projects in a distributed DevOps environment.

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 repeatable security frameworks around our GCP and AWS public cloud stacks
  • Work with SRE teams and partner teams to ensure controls are implemented and kept up to date
  • Ensure that our crypto operational services are up to date and operating safely
  • Work with the Risk Assurance team to ensure that our policies and governance are well written and achievable
  • 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 security knowledge, from high level architectural concepts down to the implementation
  • Experience securing enterprise-scale deployments in major cloud stacks (GCP is required, AWS or Azure also desired), including automating controls and use of native API functions
  • You’ve implemented strong data security models and proper secrets management where necessary, especially in a public cloud environment
  • Your work includes modern log aggregation and log analysis techniques, and you're familiar with the concepts of SIEM technology
  • A B.S. in Computer Science is fantastic, but real-world experience is preferred
