Senior Executive Assistant

The Opportunity

On our team, you'll have the opportunity to work directly alongside the executives shaping Fortreum's strategy and growth.

This position offers a motivated, detail-oriented professional the chance to sit at the center of the organization — gaining exposure to high-level decision-making, building relationships across leadership, and playing a pivotal role in keeping Fortreum's C-suite focused on what matters most.

Specifically, you would be responsible for:

• Calendar Management

  • Own and manage complex, high-volume calendars for five executives (CEO, President, CSO/CRO, CTO, CFO), resolving conflicts and making real-time judgment calls on priority.

  • Proactively schedule and reschedule meetings based on shifting business priorities, without requiring constant executive input.

  • Block focus time and protect executives' calendars from over-scheduling; flag when a week is unsustainable.

  • Anticipate scheduling needs around recurring cycles (MFRs, board meetings, QBRs, client engagements) and build calendars proactively rather than reactively.

  • Monitor and triage inboxes for executives, flagging urgent items and filtering low-priority or spam content

• Email Management

  • Draft responses on executives' behalf for routine correspondence, using appropriate tone and judgment on when executive input is needed.

  • Maintain a clear system (folders, flags, or task tracking) so nothing time-sensitive is missed.

  • Follow up on outstanding threads and ensure timely responses to internal and external stakeholders.

  • Exercise discretion in distinguishing what needs executive eyes immediately vs. what can wait or be delegated.

• Operational and Administrative Support

  • Process expense reports and manage budgets related to executive operations.

  • Maintain organized filing systems for Board and executive-level documentation.

  • Support special projects as assigned by executives.

  • Prepare brief daily/weekly summaries of calendar and inbox priorities for each executive.

  • Coordinate travel logistics (domestic and international) tied to calendar commitments.

  • Support meeting prep by ensuring relevant materials are attached or linked to calendar invites.

  • Act as a gatekeeper: managing incoming meeting requests and inbox volume so executives can focus on strategic work.

This is a hybrid position based out of our Lansdowne, VA headquarters, requiring in-office presence 2 days per week to support in-person coordination with the executive team.

• 5+ years supporting senior executives with heavy emphasis on calendar and inbox management, ideally across multiple executives simultaneously.

• Advanced proficiency in Outlook/Microsoft 365 (calendar tools, rules, delegate access, focus time features).

• Excellent judgment in prioritization: able to distinguish urgent vs. important without hand-holding.

• Strong written communication skills for drafting emails in an executive's voice

• High discretion with confidential and sensitive information.

• Comfortable managing ambiguity and shifting priorities across four distinct working styles.

• Experience in government contracting, consulting, or professional services.

• Hands-on experience with SharePoint, Teams and other Microsoft 365 collaboration tools.
