Responsibilities

Your Work

In this role, you will:

  • Perform complex administrative, analytical, and procedural work with a high degree of autonomy, sound judgment, discretion, and attention to detail.
  • Manage administrative matters in the absence of, or on behalf of, the CISO, using established priorities, decision rights, and escalation paths.
  • Own the CISO’s calendar and daily operating rhythm, including prioritizing requests, resolving conflicts, protecting focus time, and ensuring the executive is prepared for key decisions and commitments.
  • Coordinate closely with the ISRO Chief of Staff and leadership team to align calendars, agendas, materials, decisions, action items, and follow-through across department-wide priorities.
  • Prepare and manage leadership cadences such as CISO staff meetings, ISRO leadership meetings, all-hands meetings, planning sessions, executive reviews, customer discussions, audit and compliance reviews, and other recurring forums.
  • Develop meeting agendas, pre-reads, briefing materials, notes, decision summaries, and action trackers; confirm owners and due dates and follow up to closure.
  • Serve as an administrative liaison among the CISO, Chief of Staff, ISRO leaders, employees, enterprise partners, customers, vendors, and external contacts.
  • Handle sensitive and confidential information related to cybersecurity, risk, audit, compliance, investigations, organizational planning, staffing, vendors, and executive decisions with appropriate care and need-to-know discipline.
  • Independently plan leadership meetings, workshops, employee events, and organizational sessions, coordinating facilities, food, technology, accessibility, and security requirements at approved locations.
  • Coordinate domestic and international travel arrangements, itineraries, contingency plans, and supporting logistics for the CISO and, when requested, ISRO leaders.
  • Process and monitor expense reports, invoices, purchase and travel approvals, and other administrative transactions through Concur and designated enterprise systems, ensuring completeness and policy compliance.
  • Support third-party and vendor administration by coordinating meetings, documentation, approvals, onboarding steps, renewals, and follow-ups with procurement, finance, legal, and ISRO owners.
  • Maintain ISRO distribution lists, leadership rosters, organizational charts, contact lists, team calendars, SharePoint content, and other department records as assigned.
  • Help establish consistent administrative practices across ISRO, including templates, intake and routing conventions, meeting norms, records organization, and executive communication workflows.
  • Coordinate urgent communications and meeting logistics for time-sensitive security, risk, audit, compliance, or operational matters while following established incident and escalation protocols.
  • Use Microsoft Copilot and other approved AI capabilities to streamline scheduling, prepare summaries, improve information retrieval, automate repeatable administrative work, and create practical agents or workflows where appropriate.
  • Model responsible use of AI by protecting confidential information, validating outputs, following company policies, and sharing effective administrative practices with the broader admin community.
  • Anticipate operational gaps, identify opportunities to remove administrative friction, and recommend improvements that help ISRO leaders make decisions and execute more effectively.
  • Provide backup and partnership support to other executive assistants and administrative professionals across Technology and the Ascendiun family of companies as business needs require.

  • Advanced proficiency in Microsoft Outlook, PowerPoint, Word, Excel, Teams, SharePoint, and Copilot is required.
  • Working knowledge of Lucidchart is preferred; familiarity with Planview, Jira, Confluence, Service Marketplace, Concur, UltiPro or comparable enterprise platforms is a plus.
  • Demonstrated ability to manage a dynamic executive calendar, recognize competing business priorities, and make appropriate trade-offs with limited direction.
  • Exceptional written and verbal communication skills, including the ability to prepare polished executive materials, capture decisions accurately, and communicate with tact across all organizational levels.
  • Strong organizational and follow-through skills, with the ability to manage multiple workstreams, deadlines, and stakeholders without losing detail or momentum.
  • Demonstrated discretion and sound judgment when handling confidential, restricted, or sensitive business and security information.
  • Ability to remain calm, flexible, resilient, and solutions-oriented during urgent requests, shifting priorities, and periods of organizational change.
