Job description

Founder details will be shared during the interview process, in alignment with privacy and confidentiality requirements.

A Silicon Valley-based family office supports early-stage investing, operating companies, and personal ventures, and has been recognized as a top early-stage investor. The Executive Assistant provides direct support to the principals across scheduling, communications, travel and logistics, vendor coordination, and day-to-day execution.

This role requires excellent judgment, clear and precise communication, and strong calendar and logistics management, along with comfort operating in a high-trust, high-context environment. The Executive Assistant works closely with senior leaders, founders, investors, and their executive assistants, serving as a thoughtful filter and force multiplier for the principals' time.

This is not a traditional EA role. It is designed for someone who wants ownership, complexity, and long-term growth in a fast-moving, execution-focused environment.

The principals are serial entrepreneurs and investors with deep experience building and scaling venture-backed companies, including businesses backed by leading Silicon Valley investors. Together, they manage a family office, oversee multiple operating companies, and continue to launch new ventures across technology and healthcare.

Responsibilities

Business & Operations (≈70%)

• Manage complex calendars and scheduling with senior stakeholders (investors, fund partners, portfolio founders)
• Handle professional communication on behalf of principals
• Coordinate domestic and international travel
• Support expense review, categorization, and coordination with bookkeepers
• Build and maintain operational systems (intake forms, trackers, workflows)
• Research and book restaurants, meeting spaces, and conference rooms (US & Europe)
• Maintain strict confidentiality and information hygiene
• Proactively identify gaps, inefficiencies, and process improvements

Personal & Household Operations (≈30%)

• Coordinate household vendors (housekeeping, plumbers, gardeners, contractors) - owning contractor relationships end to end, not just scheduling them
• Manage household logistics and urgent requests
• Support onboarding and oversight of household staff
• Help scale household operations as needs grow (e.g. new vendors, childcare support)

This role is not a fit if you

• Want a strictly 9-5 role
• Prefer narrowly defined EA tasks
• Need constant direction for standard workflows
• Are uncomfortable supporting both business and personal operations

Requirements

What We're Looking For

Required

• 3+ years supporting an executive directly - operating at the pace and responsibility of an exec's right hand (Chief of Staff, startup ops, or senior EA roles with real ownership all count)
• Experience supporting US-based executives, working US hours
• Confident, professional written and spoken English - strong enough to comprehend and respond in your own words in real time (accent is fine; clarity and fluency are what matter)
• Strong judgment, discretion, and comfort handling sensitive information
• Highly independent, proactive, and systems-oriented
• Comfortable juggling business and personal responsibilities
• Active daily use of AI tools (e.g. ChatGPT, Gemini, DeepSeek, etc.) to work efficiently - using AI to amplify your own thinking, not replace it

What separates the right hire

• Operates unsupervised - once something is handed over, it's off the principal's mind
• Proactive: flags problems early, arrives with solutions, closes loops alone
• Absorbs feedback once; the same error doesn't recur
• Sound judgment on what to handle, what to shield the principal from
• Full-scope comfort across business, household, property, vendors, and personal logistics
• Discretion by reflex with sensitive financial and personal …
• Detail-oriented and calm under pressure

Tools

• Google Workspace (required)
• Ability to quickly learn and use Airtable
• Familiarity with Notion or similar tools is a plus

Working Hours

• 8:00 AM-5:00 PM Pacific, weekdays
• Occasional weekend responsiveness (30-60 minutes) when something time-sensitive breaks - a cancelled flight, an event falling through. This won't happen every weekend, but stepping in when it does should feel obvious, not like an imposition
• Flexibility required during international travel (short-term Europe coverage)

Benefits

Growth Opportunity

This role has no fixed ceiling. Over time, it can grow into broader operations leadership, Chief of Staff-level ownership, or expanded responsibility across new ventures.

What We Offer

• Full-time role. We won't consider candidates planning to combine this job with another one.
• Remote work. You may be located in almost any country - you'll just need a good internet connection, a computer, and the ability to adjust your schedule to overlap with the team.
• Growth opportunities to learn and grow inside the family business.
• Salary discussed during the interview. Paid in USD.
• Application deadline: ASAP. The later you apply, the more compressed your selection process will be (e.g. less time for the test assignment).
