Senior Executive Administrative Assistant
Position Summary
Since Axiom Space is a very complex work environment, we are looking for a resilient, high-energy Senior Executive Administrative Assistant who is a dedicated operational and administrative partner to both the Chief People Officer (CPO) and the Chief Information Officer (CIO), providing equal and consistent support across both offices.
Key Duties & Responsibilities
Manage complex, high-volume calendars for both the CPO and CIO, proactively aligning schedules with their respective priorities and resolving conflicts with sound judgment.
Cook domestic and international travel for both executives, including end-to-end itinerary planning, visa requirements, and day-of logistics.
Process and reconcile expense reports for both principals in a timely and accurate manner, ensuring full compliance with company expense policy.
Prepare agendas, pre-reads, and briefing documents for all CPO- and CIO-led or attended meetings, ensuring both executives are fully prepared for every engagement.
Own action item tracking across both offices — following up with owners, escalating delays, and ensuring commitments are closed on time.
Run open items, deliverables, and priorities to ground on behalf of both executives, proactively closing gaps without waiting to be asked.
Track the status of ongoing initiatives and cross-functional commitments for both the CPO and CIO, surfacing risks or delays in a timely manner.
Cook cross-functional work between the People and Technology teams, ensuring information flows accurately and operational handoffs are clean.
Serve as the primary administrative liaison between the CPO's and CIO's offices and the broader organization, ensuring clear communication and timely follow-through.
Partner with the Chief of Staff and support team across executive offices to ensure alignment between the CPO's and CIO's priorities and CEO-level strategic objectives.
Develop and maintain SOPs and process documentation for recurring activities within both the CPO's and CIO's offices.
Leverage project management and productivity tools (including Jira and Microsoft 365) to manage workstreams, track deliverables, and maintain operational accountability.
Qualifications
Bachelor’s degree in Business Administration, Operations, Communications, Human Resources, or a related field.
10+ years of experience in a senior executive assistant or executive administrative role supporting C-suite leadership, within a startup where priorities shift quickly.
Experience supporting multiple executives simultaneously in a fast-paced, high-complexity environment strongly preferred.
Demonstrated experience managing executive travel and expense reporting, including international travel coordination and policy compliance.
Familiarity with People (HR) and/or Technology (IT) functions a plus — demonstrated ability to quickly learn the language and priorities of new functional domains.
Proficiency in Microsoft 365 (Outlook, Teams, SharePoint, OneNote) and project management tools (Asana, Monday.com, Jira, or equivalent).
Demonstrated ability to manage competing priorities across multiple principals with equal responsiveness and quality — never letting one principal’s needs eclipse the others.
Proactive and anticipatory: stays one step ahead of both executives, identifies needs before they arise, and closes gaps independently.
Collaborative and aligned: partners naturally with the Chief of Staff support team and the Executive Operations Manager, understanding that coordination across the C-suite is a shared responsibility.
Trusted and discreet: handles confidential people, technology, financial, and organizational information across two sensitive executive domains with the highest level of integrity and professionalism.
