Executive Assistant

Kantiv•San Diego, CA

About The Position

We are rebuilding how architecture, engineering, and construction firms run their marketing and revenue operations. We work with the firms that design and build the physical infrastructure around us: the buildings, bridges, hospitals, transit systems, and water plants that everyone uses and almost nobody thinks about. Our team genuinely loves this industry. AEC moves billions of dollars through workflows that still rely on spreadsheets, email threads, and tribal knowledge, and our AI-powered platform replaces that mess with software that actually understands how AEC teams pursue work, win it, and deliver it. We’re early, we’re moving fast, we’re hyper customer-centric, and we’re building the system of record for AI for an industry that’s never had one.

Requirements

3-5+ years supporting founders or senior executives, ideally at a startup or fast-moving tech company
You’ve supported a high-output executive in a fast environment and you kept up
You’ve planned real travel, not just booked a flight; you know what to do when the 6am to JFK cancels at 4am
You write well.
You’ve held confidential information and never been the leak
Comfortable in Google Workspace, Slack, and whatever new tool we throw at you next month

Nice To Haves

You over-communicate by default and never make people wonder what’s happening
You ask “why” before you ask “how”: understand the goal, then build the plan
You don’t wait for a process to exist before you can use one; you build the process
Nothing falls through the cracks on your watch
You bring up problems with a proposed answer attached
You feel a customer’s urgency the same way the CEO does
Curious about AEC or excited to learn it; this industry rewards people who actually engage with how things get built
Startup experience is a plus
AEC experience is a bigger plus
Neither is required if you can show the judgment

Responsibilities

Protect the CEO’s time strategically without being a rigid gatekeeper
Own a complex CEO calendar across multiple time zones, with more execs added over time
Eliminate time leakage: kill meetings that don’t need to happen, shorten the ones that do, batch the rest
Make tradeoff calls on competing requests without escalating every one
Build a calendar that reflects real priorities, not just whoever asked loudest
Protect deep work blocks like they’re customer meetings
Build automations where you can
Be the front door for customers, investors, partners, and candidates reaching the CEO
Draft and send emails on behalf of the CEO
Triage inbound: ruthlessly prioritize what gets a fast reply, what gets a holding message, what gets escalated, what waits
Handle confidential conversations (board, fundraising, hiring, customer issues) with the discretion the role demands
Plan domestic and occasional international travel: flights, hotels, ground, agendas, expense reconciliation
Coordinate trips to customer sites, which often means jobsite visits, regional AEC offices, and industry conferences (AIA, ENR events, AEC tech summits)
Run offsites, dinners, and customer visits in San Diego and on the road
Help the people you support keep their lives running so they can keep the company running
Backup project work
Occasionally pick up a discrete project end-to-end when it lands between functions
