Executive Assistant to the CTO

About Us

The 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 Overview

The ideal candidate brings 3+ years of experience supporting founders or C-suite executives in fast-paced environments. You thrive under ambiguity, exercise sharp judgment without hand-holding, and communicate with exceptional conciseness. Highly fluent in Google Workspace, Slack, and modern AI tools, you combine low ego with high standards to solve problems before they reach the CTO's desk.

Responsibilities

• Own the CTO's calendar: scheduling, prioritization, protecting focus time across EMEA, US and APAC time zones
• Organize travel end to end: flights, hotels, logistics, changes on the fly
• Triage inbox and messages; draft replies and follow-ups in his voice
• Prepare meetings: agendas, briefs, background on people and companies
• Chase follow-ups and open threads across the leadership team
• Coordinate internal events, offsites and board meeting logistics
• Handle confidential material (hiring, comp, M&A) with full discretion
• Occasional personal scheduling where it intersects with work commitments.

Requirements

• Judgment under ambiguity: you make dozens of small calls a day without checking in, and you get them right
• Proactive ownership: you notice problems and fix them before anyone asks
• Absolute discretion with sensitive information
• Sharp, concise written communication that can pass as the CTO's own
• Low ego, high standards: the job is invisible when done well
• Fluent with Google Workspace, Slack and modern AI tools
• 3+ years supporting a founder or C-level executive preferred
• Italian and English fluency is required; Mandarin is a plus

Why Join Us?

• We’re a mission-led team solving tough, meaningful problems
• You’ll have autonomy and impact from Day 1
• We’re growing fast—which means so will your opportunities
