Executive Assistant, GTM Team

Miami, Florida, United States

About Us

OpenFX is on a mission to move money as freely as data, unrestricted by time zones, banking hours, or legacy systems. We are building the infrastructure that will power the next generation of cross-border payment systems for institutions. Our stellar early team brings experience at companies such as J.P. Morgan, Goldman Sachs, FalconX, PayPal, Affirm, Kraken, Nium & others. We're backed by Accel, Lightspeed, NfX, and other top-tier investors.

About the Role

As Executive Assistant, GTM, you will be the strategic and administrative partner to OpenFX's Head of Go-To-Market and the operational owner of our Brickell, Miami office – roughly 70% executive support, 30% office operations. Your job is to multiply the Head of GTM's capacity: you own their calendar, meeting preparation, follow-through, travel, and event logistics, so their time can focus on the revenue-critical work only they can do, and you keep the office running smoothly even when they are on the road.

This is a role for a force multiplier, not a booking queue: you anticipate needs from business context, protect time diplomatically, and close every loop without supervision, with trust and discretion at the core of everything you do.

What You'll Do

• Own the Head of GTM's complex, multi-time-zone calendar and inbox by vetting requests, prioritizing meetings, triaging inbound requests, and recommending trade-offs so time stays protected for the highest-impact revenue work.
• Prepare briefing documents ahead of every external meeting – attendees, context, objectives, open items, and recommended talking points – so the Head of GTM never walks in cold.
• Build and run the follow-through system that supports executive relationships, board and investor deadlines, and weekly action items, so commitments are tracked, chased, and closed.
• Use AI daily for meeting prep, summaries, and first-draft communications, and build reusable AI workflows that speed up the whole GTM operating rhythm.
• Draft routine external communications – scheduling, follow-ups, introductions – that go out under the Head of GTM's name with light-touch edits.
• Coordinate logistics for leadership hiring – interview loops, candidate travel, and onsite hosting – so searches keep moving at pace.
• Own travel and event execution end-to-end, from itineraries to executive dinners and side events, anchored in flagship industry events like Money 20/20.
• Run the Brickell office – vendors, facilities, supplies, building relations, and continuity planning (including hurricane preparedness) – so the office runs to standard even during executive travel.
• Host clients, partners, and investors visiting the office, and make every new hire's first day seamless, from desk and equipment to accounts and badge.

What You Should Bring

• 3-5 years supporting C-suite or senior executives in fast-paced, high-growth environments.
• Anticipation grounded in business context: you read the pipeline, the board calendar, and org priorities, not just the calendar.
• Independent judgment and diplomatic gatekeeping: you know which escalations outrank an internal sync, and you redirect requests to the right owner rather than blocking.
• Ownership and follow-through: you close loops without supervision, drive open commitments to done, and hold yourself to measurable outcomes.
• Outstanding written and verbal communication, with drafts strong enough to ship under an executive's name.
• A high degree of trust and discretion with confidential material – customers, pricing, fundraising – in a regulated fintech.
• Expert command of Google Workspace, Slack, and Notion, plus daily working fluency with AI tools like Claude.
• Executive presence with board members, investors, and C-level partners, and a warm front-of-house presence for anyone visiting the Miami office.
• Comfort coordinating vendors, purchasing, and facilities workflows with accuracy and timeliness.
• Comfort with ambiguity and iteration, a bias for action and urgency, and the instinct to build strong relationships across GTM, People and Recruiting, Finance, and Legal.

Even Better

• Experience in fintech, payments, or financial services.
• Experience combining executive support with office management at a startup.

• Competitive salary and benefits package
• Equity in a rapidly growing company
• Opportunity to make a significant impact on the global financial infrastructure
• Collaborative work culture with emphasis on personal and professional growth
