Executive Assistant & Office Lead

About the role

We’re looking for the person who makes everything - and everyone - at Junior tick. You’ll help make our NYC office a brilliant place to work, bring people together, and keep our CTO’s day running smoothly.

This isn’t a typical Executive Assistant role. Think 80% office, people, events and culture; 20% supporting our CTO.

We’ve grown quickly, and we’re just getting started

• $30M revenue run rate, with 10× revenue growth in 2025
• Bootstrapped and profitable, with no outside investors
• 70+ people across New York, London, Singapore, and Sydney
• Trusted by 20 of the world’s top 30 private equity funds and 18 of the top 20 strategy consulting firms
• Saving customers an average of 60 hours per due diligence project

About the Role

You’ll own the experience of working in our Flatiron office - from the everyday details that make people feel welcome to the big moments that bring the team together.

You’ll also work directly with Nico, our Co-founder and CTO, helping him stay organised and focused on the work that matters most.

No two days will look the same. You might be welcoming new engineers, planning a company offsite, organising a team dinner, or untangling a calendar puzzle. You’ll spot what needs doing and make it happen.

What You’ll Do

Make Our Nyc Office a Great Place to Work

• Be the friendly first point of contact for our team, candidates and visitors.
• Keep the office welcoming, organised and running smoothly.
• Create thoughtful ways to bring people together and make office life enjoyable.
• Own relationships with vendors, building management and service providers.

Bring People Together

• Organise team lunches, socials, celebrations and other events.
• Plan company events and international off-sites, from venue research to on-the-day details.
• Make new starters feel at home from day one.
• Look for opportunities to make the team’s time together more fun and meaningful.

Support Our Cto

• Own Nico’s calendar and help him spend his time on the right priorities.
• Coordinate meetings, travel and other logistics.
• Keep track of important communications, follow-ups and commitments.
• Anticipate scheduling conflicts and other issues before they become problems.
• Build the trust to take action without needing to be asked twice.

Keep Improving How We Work

• Coordinate office onboarding, equipment, deliveries and workplace logistics.
• Build simple processes as the company grows.
• Take ownership of the unexpected challenges that come with startup life - including the occasional coffee machine crisis.

Who We’re Looking for

You’ll probably enjoy this role if you

• Love meeting people and making them feel welcome.
• Take initiative and follow through without needing much direction.
• Stay calm and organised when plans change or several things need attention at once.
• Care about the details, from a new starter’s first day to the flow of an event.
• Have good judgement, communicate clearly and handle sensitive information with discretion.
• Bring ideas, a sense of humour and a genuine interest in making work better for the people around you.

Experience We’d Like to See

• 3+ years in executive assistance, office management, workplace experience, people operations or a similar role.
• Experience organising events, off-sites or team gatherings.
• Confidence supporting founders or senior leaders and working across teams.
• Experience in a startup or fast-growing technology company is a plus.
• Comfort with modern tools and finding practical ways to make work run more smoothly.

Additional information

Bonus points if you’ve helped scale an office, supported a founder, or worked in AI or another fast-growing technology business. We care more about what you’ve done than the title on your LinkedIn profile.

Why Junior

You’ll have real ownership and room to shape how our NYC office works as the company grows. You’ll work closely with our founders, get to know people across the business, and have a meaningful hand in the culture we’re building.

We take building a brilliant company seriously. We don’t think that means taking ourselves too seriously.

Logistics

• Location: Flatiron, New York City
• Working style: In office, Monday-Friday
• Salary: $100,000-$150,000 base, depending on experience
• Benefits: Equity, healthcare and gym benefits, breakfast and lunch in the office, and opportunities to travel for company off-sites

We’re looking for someone who makes new starters feel at home, brings people together and makes the everyday run a little better. If that sounds like you, we’d love to meet you.
