About this team and role :

What is a Staff Software Engineer at Mozilla?

A Staff Software Engineer is the next level from a Senior Software Engineer. At Mozilla this role can vary but typically a Staff Engineer is a domain expert who leads others within a single team to tackle multi-month projects. Tasks that may be initially ambiguous or require significant planning and require them to influence or direct the work of several engineers. They sequence deliverables and manage risks in their team's projects, provide feedback on our strategy and goals affecting the team, and turn our strategy into action for their team members. Staff Software Engineers mentor others by stewarding some responsibilities to more junior and senior engineers so they can take on new ones. They collaborate with management on building team consensus and providing direction. Staff Software Engineers identify gaps and opportunities for improvement to enable a culture of inclusion and allyship, at all levels of the organization.
