Senior Executive Assistant, CEO

About Sent

Sent is an infrastructure for sending A2P messages across SMS, WhatsApp, and RCS through a single unified API. Our intelligent routing model automates channel selection based on deliverability and cost, ensuring lower cost and global reach without any channel-specific integrations.

We recently closed a $12M Series A backed by Companyon Ventures, Bessemer Venture Partners, UIF, and others. We’re hiring to build the best infrastructure to replace multi-channel messaging stacks.

About the role

We’re looking for a senior executive assistant to work directly alongside our Founder & CEO. You’re someone who can manage a complex calendar, write a clear response, spot a conflict before it becomes a problem, and keep commitments moving without constant direction. You understand that great executive support depends as much on judgment and trust as it does on organization.

You’ll own the day-to-day coordination behind the CEO’s calendar, inbox, meetings, travel, and follow-through. You’ll learn his priorities, protect time for the work that matters most, and make sure he has the context he needs for each conversation. You’ll also build the systems that make this support more reliable as Sent grows.

This is a full-time, in-office role in NYC. Working hours vary wi
