• Strong coding skills in any programming language, with experience building and maintaining production software
• Demonstrated technical experience leading the design and delivery of large, complex software projects from early definition through production launch.
• Experience leading and unblocking a group of engineers on a substantial project as a senior individual contributor.
• Significant hands-on coding as a senior IC leader in the last year.
• Ability to work across systems and technologies, learn unfamiliar codebases, and make thoughtful technical trade-offs
• Ability to operate effectively in high-ambiguity environments: framing problems, making durable technical decisions, and creating an actionable path forward.
• Excellent cross-functional and cross-organizational collaboration skills, with the ability to align teams with different systems, priorities, and constraints.
• Understanding of basic data science concepts, like linear models, precision, recall, and more

• Work directly with users to understand emerging threats and turn those insights into broadly useful products
• Partner with ML engineers and data scientists to bring new signals, models, and AI capabilities into production
• Own projects end to end, from technical design and implementation through rollout, measurement, and iteration
• Uphold a high bar for engineering quality, reliability, and product craft while moving quickly as threats evolve

Degree language

• Experience building consumer products at scale, particularly products that require a high degree of user trust.
