# Senior Full Stack Engineer

Building a New Foundation for Cloud Security The best security control doesn't detect a bad action. It removes the ability to perform it in the first place. That's what Act does. We're an action-centric cloud security company focused on reducing cloud risk by removing excessive and unintended access across cloud environments. As AI is making attacks faster and less predictable, patching and detection can only go so far. So we make sure every identity in the cloud, human or machine, has only the access it actually needs, without turning security into an operational burden. We're early-stage, well-funded, and built by repeat security operators who previously created Medigate (acquired by Claroty). We're building a team of exceptional people who take ownership from idea to outcome, with the autonomy to make decisions and drive their work forward. We care deeply about the customer, move fast, and enjoy building together. If you want to build something that matters from the ground up and see your work go live within days, this is the place. The role We are looking for an experienced Senior Full Stack to join our team and own features end-to-end - from the UI down to the backend services
