Our mission-driven team is seeking a bold and dynamic Executive Assistant who is fueled by high accountability, execution horsepower, and driven to understand our world, science/technology, and life itself, for the benefit of all on Earth and beyond.
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. This role is designed for a seasoned executive support professional who thrives at the intersection of administrative excellence and operational execution — someone who not only keeps both executives’ daily environments running with precision, but also takes ownership of driving initiatives, projects, and priorities to completion.
This is not a purely administrative role. While the Senior Executive Administrative Assistant manages calendars, travel, expenses, and meeting logistics with the highest level of professionalism, they are equally expected to run things to ground — tracking deliverables, following up on open items, facilitating cross-functional coordination, and ensuring that nothing falls through the cracks across two fast-moving executive offices.
The Senior Executive Administrative Assistant works in close alignment with the Chief of Staff support team, including the Executive Operations Manager within the Office of the CEO, to ensure that the CPO’s and CIO’s priorities are coordinated with enterprise-level objectives and that cross-functional work moves with clarity and accountability.
Dual Executive Partnership — CPO & CIO
Supporting two Chiefs simultaneously requires a high degree of organization, judgment, and the ability to manage competing priorities without sacrificing quality or responsiveness for either principal. The Senior Executive Administrative Assistant is expected to:
- Maintain equal visibility into both executives’ priorities, commitments, and operational needs, proactively surfacing conflicts, gaps, or alignment opportunities between the two offices.
- Understand the distinct domains of each principal — the CPO’s focus on people strategy, talent, culture, and organizational effectiveness, and the CIO’s focus on technology, systems, digital infrastructure, and information security — and tailor support accordingly.
- Serve as a trusted point of contact for both offices, managing communications, requests, and escalations with discretion and sound judgment
- Coordinate between the CPO and CIO offices when initiatives, decisions, or stakeholders intersect — ensuring both executives are operating with the full picture.
- Partner with the Chief of Staff support team, including the Executive Operations Manager, to ensure the CPO’s and CIO’s priorities are visible at the enterprise level and aligned with CEO-level strategic direction.
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.
- Coordinate 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.
- Coordinate 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.
