Executive Assistant to the CTO

About UsThe physical and digital worlds are merging. Vehicles, medical devices, industrial systems, critical infrastructure: security hasn't kept pace. AI is accelerating everything, from the capabilities of the systems we depend on to the sophistication of the threats targeting them. A software vulnerability can now have physical consequences. A physical breach can compromise entire digital ecosystems. Billions of devices operate with little to no protection, and traditional approaches can't keep up. Not at this scale, not at this speed, and not across this diversity of systems.Exein exists to solve this. We build the security layer for a world where physical and digital threats are no longer separate problems, from kernel-level runtime protection on embedded devices to cloud-native platforms that analyze, protect, and prove compliance across entire device fleets. We're not patching the old model. We're building security from the core out.Job OverviewWe are seeking a high-trust, proactive Executive Assistant to act as a strategic operational partner to our CTO across global time zones (EMEA, US, APAC).
