Job Description
Rhombus Power seeks an Executive Coordinator to directly support our leadership team in a fast-paced defense technology environment. This role is operational at its core: you will manage complex, ever-changing logistics, maintain tight travel and meeting coordination across multiple stakeholders concurrently, and ensure leadership can operate at speed and scale without any friction.
This is not a traditional administrative role. It requires sound judgment, discretion and confidentiality, and the ability to execute flawlessly and relentlessly under pressure—especially in managing high-volume, concurrent meeting scheduling and travel across domestic and international contexts.
This is an honorable, trusted, and key position in our organization. We expect you to be the shadow—always in lockstep supporting, guiding, directing, predicting, and executing for our leadership team. Given that this position engages directly with leadership, this role will undoubtedly provide unique opportunities to learn and engage with the leadership of an incredible, game-changing organization.
Candidates with prior experience supporting senior military leadership or operating in structured, high-accountability environments are preferred.
This position may also be involved in meetings in which management-only discussions occur so the highest level of discretion is required.
Who we seek:
Exceptionally detail-oriented with a zero-error, adaptable, mission-focused mindset
Highly dependable and responsive in time-sensitive situations
Strong sense of ownership and accountability, warrior mindset
Able to manage multiple priorities without losing precision
What Success Looks Like
Leadership operates without friction or logistical gaps
Travel is executed seamlessly, even under constant change
Priorities are anticipated—not just reacted to
Information is organized, accessible, and reliable, at all times
You are trusted to handle critical coordination without oversight
What This Role Is Not
Not event planning–focused
Not passive or reactive administrative support
Not suitable for candidates who struggle with ambiguity or rapid change
Responsibilities:
- Travel & Logistics Execution
Own end-to-end travel coordination for senior leadership. Meaning, you’ll be managing simultaneous, multi-leg domestic and international itineraries with frequent changes.
Anticipate and resolve disruptions proactively (delays, rebooking, visa constraints, etc.)
Ensure all travel aligns with company priorities, security considerations, and time sensitivity
Maintain clear, real-time visibility into who is where and when across the executive team only
- Calendars & Time Management
Manage complex calendars across multiple senior stakeholders
Prioritize scheduling based on mission-critical needs, not just availability
Rapidly adapt schedules in response to changing priorities and external demands
- Operational Coordination
Act as a central coordination node across leadership, operations, and external partners
Track key movements, engagements, meetings, and dependencies across teams
Ensure leadership is fully prepared with the right context, materials, and timing
- Communication & Discretion
Handle sensitive information with a high degree of professionalism and confidentiality
Communicate clearly and concisely across senior internal and external stakeholders
Represent leadership with professionalism in all interactions
Prior experience in the military and/or defense-related field is highly desired.
- Process Discipline & Improvement
Build and maintain systems for tracking travel, logistics, and scheduling
Identify inefficiencies and improve workflows over time
Maintain structured records and ensure nothing falls through the cracks
Experience
Prior experience supporting senior executives, operators, or leadership teams
Experience managing complex travel logistics at scale (required)
Background in military, defense, or similarly structured environments is a strong plus, especially experience supporting senior officers or leadership roles
Advanced calendar and scheduling management, with exceptional organizational and tracking systems (spreadsheets, tools, etc.)
Exceptional written and verbal communication
Ability to operate calmly under pressure and ambiguity
Salary Range
The estimated base salary range for this position is $70,000/year to $100,000/year
