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

• We 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). In this role, you will take full ownership of complex calendar prioritization, end-to-end travel logistics, inbox triaging, and high-stakes communications—drafting replies directly in the CTO's voice while maintaining absolute discretion over confidential matters (M&A, hiring, comp). From preparing meeting briefs to coordinating board events and chasing leadership follow-ups, you will keep the CTO focused and operating at peak efficiency.
• 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
