An exciting opportunity awaits an experienced Chief of Staff who is looking to support the CEO and day-to-day operations in an innovative deep-tech start-up. This is a role that would suit someone who enjoys structure and being part of a fast-paced team.

Day to Day

• Manage the CEO's inbox and calendar, prioritizing requests and maintaining flow
• Prepare high-quality documents for internal meetings, external communications, and investor presentations
• Structure and run meetings: set agendas, document outcomes, and hold teams accountable

• Support day-to-day business operations across departments
• Assist in recruiting and onboarding, from coordination to process improvement
• Maintain confidentiality and exercise sound judgment in sensitive matters

• Coordinate all business travel and accommodation logistics
• Manage executive meetings, client lunches, and events—ensuring every detail is in place
• Draft correspondence, handle admin tasks, and manage legal or board documentation
• Attend meetings on behalf of the CEO and ensure effective follow-through on action items
• Champion company culture initiatives, internal rituals, and values-driven engagement
• Act as a strategic HR partner supporting team communication, development, and planning

You'll Need

• Experience in a high-impact operational, strategic, or advisory role such as Chief of Staff, business operations lead, consultant, or product manager
• Strong organizational and time-management skills with meticulous attention to detail
• Excellent written and verbal communication skills, including the ability to draft polished documents and synthesize complex information for executive stakeholders
• High degree of professionalism, discretion, and judgment in handling sensitive information
• Proven ability to manage multiple priorities in a fast-paced, evolving environment
• Comfortable working cross-functionally across HR, Finance, Product, Legal, and other teams
• Familiarity with productivity and collaboration tools such as Clickup, Slack, Jira, or Confluence
• Analytical thinker with a data-informed mindset and strong problem-solving skills
• Experience supporting executive communications, board updates, or fundraising efforts is a plus
• Demonstrated ability to help foster a strong, values-driven team culture
• Bachelor's degree or equivalent required; MBA or equivalent experience is a plus

If you don't meet every single qualification but feel excited about this role, we encourage you to apply—we value potential and a growth mindset as much as experience.
