The ideal candidate is an expert in GTM financial management with a forward-looking mindset—equally comfortable optimizing expenses, evaluating business cases, and deploying AI-enabled forecasting tools to improve accuracy and scalability. In a fast-growing, global cybersecurity enterprise, your impact will shape how we invest resources, measure performance, and accelerate sustainable growth.
