Security Engineer

Cross-Meta Security’s mission is to protect the company, our community, and their data while empowering safe innovation. To achieve this, we are building a small team of Senior Individual Contributors (ICs) who can solve security-related technical problems across the company in collaboration with various Meta product groups and pillars.

Lead cross-organizational technical teams to solve challenging cross-domain security problems. Bring together engineering teams that work in adjacent areas to build shared context and tackle bigger problems than they can solve individually. Operate with ownership and accountability for one or more security risks at Meta and drive and influence people to do the right things to comprehensively address those risks while enabling the company to move fast. Disambiguate and decompose problems and solutions and create clarity for others. Provide technical guidance and collaborate with cross-functional partners to define projects goals and milestones. Bolster engineering excellence in everything you do.
