We’re building a world-class team to redefine knowledge work with AI

Zeno is a legal AI startup building a platform that helps lawyers research, review, and draft documents with real legal reasoning — not just text prediction. We’re developing technology that can:

• Search and retrieve statutes, case law, and commentary with high precision.
• Reason step-by-step, applying legal tests and weighing precedents.
• Explain every answer transparently, so lawyers can trace conclusions back to the exact sources.

Where most tools automate surface-level tasks, we’re focused on replicating the way lawyers actually think through legal problems, making depth and trust the foundation of everything we build.

You’re joining an early-stage startup that is already working with leading firms such as Ernst & Young, HVG Law, Banning, and many more. Backed with $3M in seed funding, we’re now scaling a team of engineers and thinkers who want to solve real problems, drive innovation, and create lasting change in the legal sector.

The role

As the first Executive Assistant at Zeno, you will provide high-level support to our three founders during a pivotal phase of growth. This role goes beyond traditional EA responsibilities: you’ll be a trusted partner in managing priorities, streamlining operations, and ensuring the founders can focus on the highest-impact work.

You’ll work closely with leadership across product, engineering, research, and operations, gaining exposure to the inner workings of a legal technology company as it scales. Your contributions will help Zeno’s leadership remain focused, effective, and aligned as we grow both our product and our team.

What you’ll work on

• Manage calendars, travel, and email for the founders and other leaders, helping them stay focused on the right priorities. Use AI tools to make their work, and yours, more efficient;
• Deep attention to detail and a strong drive for structure, ensuring work is faster, smoother, and clearer.
• Lead planning and execution of key team moments - including recurring meetings, offsites, workshops and informal gatherings;
• Filter incoming requests, safeguard focus time, and keep communication flowing smoothly across the team;
• Draft, review, and edit presentations, reports, legal documents, and strategic communications;
• Process expenses, contracts, and administrative workflows;
• Organize company events, team offsites, and client engagements to strengthen culture and relationships;
• Manage vendor relationships and office operations.

What we’re looking for

• 3–5+ years of experience as an Executive Assistant supporting senior executives (C-level preferred), with a track record of managing multiple executives simultaneously;
• Comfort with tools like Google Workspace, Slack and Notion - and a quick learner when new systems come in.
• Familiarity with legal document management systems (preferred) and interest in AI productivity tools and modern workplace technologies;
• Exceptional organizational, multitasking, and problem-solving skills, with a proactive and anticipatory approach to executive support;
• Excellent written and verbal skills in both Dutch and English and confident in handling sensitive or high-stakes communication.;
• A genuine commitment to supporting others and strengthening the team, with pride in the impact of behind-the-scenes work.

What we offer

• Be part of a product-driven team reinventing how legal professionals work;
• Join early and shape the foundation of a fast-growing, high-impact startup;
• Work from our beautiful office in the heart of Rotterdam;
• Collaborate with exceptional engineers, researchers, and entrepreneurs;
• Competitive compensation, employee benefits and a strong upside as we grow.
