Executive Assistant

Tenex•New York, NY

3d•$65,000 - $80,000•Onsite

About The Position

The Managing Partner's calendar is the firm's bottleneck. Every client escalation, every partner conversation, every decision that needs to happen this week and not next runs through one person. When that person is operating at full speed, the firm moves. When their attention is eaten by scheduling churn, inbox backlog, and follow-ups that fell through the cracks, everything downstream slows with it. That's the job. You are the operating system for the Managing Partner. You own the calendar, the inbox, the travel, and the hundred small commitments that have to be tracked and closed. You decide what reaches them and what you handle yourself. You are in the room, or close to it, on the most sensitive conversations the firm has, and you treat every one of them with complete discretion. This is not a role for someone who wants a stable, repeatable week. The work shifts with the firm, the client roster, and the technology. We expect you to use the modern agentic AI stack daily to give yourself leverage, because at Tenex an assistant who automates their own workflow is the only kind that keeps up. If you draft replies by hand that an agent could draft for you, you're doing the job on hard mode, and you won't have time for the work that actually needs a human. This role works directly with the Managing Partner and across the leadership team. It is based in our New York City office, in person five days a week.

Requirements

3+ years supporting senior executives, ideally a founder, CEO, or partner, in a fast-moving, high-confidentiality environment
Proven command of an executive inbox and calendar. You know how to triage, prioritize, draft, and keep a busy principal's communications and time under control
Daily, hands-on use of the modern agentic AI stack (Claude, Cowork, ChatGPT, and whatever ships next week). You don't just know these tools exist, you use them every day to give yourself leverage, and you'll learn the next one fast
A bias to automate. You see yourself doing the same task three times and you build a workflow so you never do it a fourth
Strong organizational instincts and attention to detail. You catch what others miss and nothing falls through the cracks
Sound judgment about when to act on your own and when to escalate
Clear, precise written and verbal communication. You understand that word choice matters when you're writing on someone else's behalf
High EQ and the ability to build trust quickly with people who value reliability over personality
Comfort running multiple high-priority workstreams at once without losing quality
High ownership, low ego, and a builder's instinct

Nice To Haves

Background as a Chief of Staff, a founder's right hand, or an ops lead at a fast-growth or AI-forward company
A track record of building automations or lightweight tools to streamline your own work, formal or informal. You can walk through exactly what you built, why, and what it saved
Experience supporting a principal through travel-heavy, client-facing, deal-driven schedules

Responsibilities

Own the Managing Partner's calendar end to end, with sharp judgment about what gets time, what gets declined, and how the week is sequenced for the highest-leverage use of their attention
Run active inbox management: triage everything incoming, draft responses in the Managing Partner's voice, flag what needs them and only them, and make sure nothing of consequence is missed
Build AI-native workflows for the work above. Use Claude, Cowork, and lightweight automation to draft, summarize, schedule, and track, so the routine runs itself and you spend your time on judgment calls
Plan and book complex travel, including client site visits roughly monthly and the changes that come with a fast-moving schedule
Track the Managing Partner's commitments, deadlines, and follow-ups across clients, partners, and the internal team, and close the loop before anything slips
Act as a coordination hub between the Managing Partner and clients, partner teams at Anthropic, OpenAI, Vercel, and beyond, and the internal Strategy and Engineering teams
Prepare the Managing Partner for what's ahead: briefings before meetings, context before calls, the right materials in the right place at the right time
Plan and run logistics for leadership offsites, client dinners, partner sessions, and firm events
Manage expenses, vendor relationships, and budgets on behalf of the Managing Partner
Handle confidential business, client, financial, and personnel information with the highest standard of discretion
