THE CHALLENGES ALONG THE WAY

1. Being Both Strategist and Executioner

One of the hardest parts of this role is that you’re both the visionary and the builder; the one drawing the mapandpaving the road.
That means switching between high-level strategy and hands-on experimentation daily, and doing it while bringing others along with you. There’s no playbook for this kind of work. You’re paving an unpaved road, one small experiment at a time.

2. Balancing Security and Innovation

ActiveFence is the leading provider of security and safety solutions for online experiences, safeguarding more than 3 billion users, top foundation models, and the world’s largest enterprises and tech platforms every day.
