Senior EA

Flex • Miami, FL

6d • $130,000 - $250,000

About The Position

Flex is building the AI-native private bank for business owners.

We’re re-architecting the entire financial system for entrepreneurs—from the first dollar a business earns to how that value compounds, moves, and is ultimately spent in real life. Banking, credit, payments, personal finance, and financial operations—rebuilt from the ground up as a single, intelligent system.

Since launching publicly in September 2023, Flex has scaled from zero to nine-figure annualized revenue, with a clear path to profitability by late 2025. We move fast, ship relentlessly, and operate with extreme ownership.

Our customers are affluent business owners ($3–$200M in revenue)—the backbone of the economy and one of the most underserved segments in finance. They’re stuck with outdated banks and fragmented tools. We’re replacing all of it. The opportunity is massive: a ~$1T+ revenue market hiding in plain sight. Our ambition is to build a $100B+ company by delivering a product that is fundamentally better—not incrementally improved. Flex has raised $100M+ in equity and $300M+ in debt.

This is not a traditional EA role.

You will act as the CEO and executive team's operating system — owning time, information flow, priorities, and execution across business and personal domains. You are ruthless about leverage, allergic to chaos, and exceptional at anticipating problems before they exist.

If done well, this role 10x’s the company. If done poorly, it doesn’t work at all.

We are looking for someone who has already operated at this level.

Requirements

• 8+ years supporting a Founder, CEO, or ultra-high-performing investor/executive
• You’ve operated in high-growth, high-pressure environments
• You think in systems, not checklists
• You have elite written and verbal communication skills
• You are calm under chaos and decisive under ambiguity
• You have impeccable judgment and know when to push back
• You are deeply discreet and ethically bulletproof
• You derive pride from making a company unstoppable

Responsibilities

• Time & Priority Control
• Own the CEO’s calendar end-to-end with zero tolerance for low-leverage meetings
• Actively shape days and weeks based on strategic priorities, energy, and deadlines
• Manage relationship's with investors, executives, partners, and in some contexts... friends and family
• Prepare daily and weekly briefs: what matters, what’s coming, what can wait
• Information & Execution Hub
• Be the single intake point for inbound: email, text, Slack, WhatsApp, etc
• Triage ruthlessly: respond, delegate, escalate, or kill
• Track open loops across work and personal life until closed
• Ensure follow-ups happen without the CEO needing to remember
• CEO Force-Multiplier
• Anticipate needs 1–3 steps ahead (travel, meetings, decisions, sensitivities)
• Pre-read meetings and surface risks, context, and landmines
• Draft emails, messages, and responses in the CEO’s voice
• Act as a trusted thought partner, not just an executor
• Personal Operations (Yes, This Matters)
• Travel planning across complex, multi-city schedules
• Household coordination, logistics, appointments, and life admin
• Discretion and emotional intelligence across sensitive relationships
• Reduce cognitive load so the CEO can operate at peak performance

Benefits

• Flex is growing quickly — you’ll help shape the direction of a product and company with real momentum.
• We’re well-capitalized with strong backing and a clear long-term vision.
• You’ll work with a sharp, driven team that values autonomy, clarity, and quality.
• Join ambitious builders who care deeply about winning together — and having fun while doing it.
• Annual team on-sites. From Bogota to Mexico City, the entire Flex team gets together once a year to align and build camaraderie.
