Chief of Staff (gn) @ Seed Stage Healthtech AI Venture, Warsaw

This is an Atlantic Labs portfolio venture. Find out more about us and other ventures in our portfolio here. 

About the Venture

We're a seed stage venture pioneering relationship-based healthcare through tech. Born from a leading global healthcare innovation program, we've built one of Europe's most popular secure medical communication platforms, connecting thousands of doctors across 20+ specialties with their patients.

Our mission is simple but transformative: making constant, trusted contact between patients and their doctors the new standard of medical care. We've turned "having your trusted doctor in your phone" from a vision into reality, creating a secure platform that strengthens the doctor-patient relationship rather than replacing it.

Backed by leading European investors, we're scaling across multiple markets while staying true to our core belief: healthcare works best when it's personal, accessible, and built on lasting relationships. Join us in reshaping how millions of people access and experience healthcare.

About the Role

This is the founder's right hand. As Chief of Staff, you'll scale the CEO's presence and impact as the business grows, ensuring critical work gets done and nothing falls through the cracks during expansion.

You'll jump across functions to solve problems, drive key projects forward, and keep the business moving through complexity and change. You'll own internal operations—process design, cross-team coordination, and keeping projects on track—while also handling external responsibilities that need CEO-level judgment but dedicated execution.

We're looking for someone with high energy, proactive instincts, and structured thinking. You're analytical but move fast, comfortable with ambiguity, and bring entrepreneurial flair to execution. This role is the backbone that allows a scaling startup to stay agile while growing up.

What You’ll Do

• Act as the CEO's operational partner -  Manage priorities, coordinate across leadership, prep for investor meetings, and ensure critical projects move forward

• Work across the business to solve problems - Jump into finance, people operations, IT, legal, or any area that needs attention to keep things running smoothly

• Own core operational functions - Manage relationships with external partners (accountants, PEOs, legal counsel, vendors) and ensure compliance, payroll, expenses, and workflows run on time

• Enable the leadership team - Coordinate across the CEO, CTO, Head of Product, and Head of Growth to ensure alignment, communication, and progress on key initiatives

• Support the team - Handle onboarding and offboarding, manage company tools and setup, and help employees with what they need to do their best work

• Bring the team together - Organise events and internal communications that keep a remote, international team connected

About You

• Significant startup operations experience, ideally supporting leadership through a company's growth journey (bonus if you've come from top-tier consulting or banking previously)

• Track record of managing operations including vendors, procurement, and process management

• Takes ideas and runs them as full projects with ownership, structure, and strong team collaboration

• Excellent communication across all levels - from external investors and C-suite to junior team members and interns

• Expert with modern collaboration tools like Google Workspace, Slack, and project management platforms

• Strong grasp of HR and finance administration processes with the ability to coordinate across external partners

• Highly proactive with the instinct to anticipate needs before they're voiced

• Strong problem-solving skills and resourcefulness when facing ambiguity or new challenges

Why Join?

• Work directly with the CEO as their operational partner in a VC-backed, internationally scaling healthcare business

• Own your impact from day one across all facets of the business - from operational execution to high-level strategy - and get a full view of what it takes to build and scale a company

• Participate in the company's growth through ESOP and equity

• Work on technology that genuinely matters using AI to solve real challenges in healthcare and improve patient care
