Mjolnir Security • Toronto, ON

About The Position

We're hiring an Executive Assistant to support our CEO and senior leadership directly. This isn't a role for someone who waits to be told what to do. You'll be trusted with sensitive information, expected to operate several steps ahead, and relied on to keep leadership focused on what matters. If you thrive in complex, fast-moving environments and take pride in making things work without friction, we want to hear from you.

Requirements

• 3+ years in an Executive Assistant or Chief of Staff–adjacent role, ideally in technology, professional services, or a similarly demanding environment
• Experience supporting a founder or C-Suite executive, not just a department head
• Proficiency in Microsoft 365 — Outlook, Teams, Word, Excel, PowerPoint — at a level beyond basic use
• Strong written communication: you can draft a crisp email, a tight briefing, or a board-ready summary without heavy editing
• Comfortable with ambiguity, tight timelines, and shifting priorities
• Discretion is non-negotiable; you'll have access to information that doesn't leave the room

Nice To Haves

• Familiarity with cybersecurity, IT, or technical professional services is a genuine advantage — you don't need to be a practitioner, but you should be able to follow the conversation

Responsibilities

• Manage the CEO's calendar, communications, and priorities with minimal direction
• Own scheduling across internal teams, external clients, legal counsel, and strategic partners
• Attend leadership and client meetings; capture decisions and drive action item follow-through
• Prepare polished presentations, briefings, reports, and correspondence on behalf of executive leadership
• Review, organize, and track contracts, proposals, SOWs, and sensitive documentation
• Coordinate logistics for client engagements, board meetings, and strategic events
• Serve as a communications bridge between the executive team and internal departments, vendors, and partners
• Handle confidential information — personnel matters, legal files, client data — with absolute discretion
• Support operational and strategic initiatives as they arise
