Legal Counsel (m/f/d)

Remote Europe

Hello 👋  I'm Robert, Finance & Legal Lead at Kayzen and I'm now looking for a Legal Counsel to join our team. As we scale our business globally - managing an increasingly complex client and vendor landscape, navigating cross-border data privacy requirements, and growing our equity and corporate structure - we need a sharp, pragmatic, and commercially minded legal mind to own our legal function. You will take what we have built so far and professionalise, scale, and strengthen it. Working closely with our Finance & Legal Lead, you will be a true business partner to senior leadership across the company.

The role

As Legal Counsel, you will be Kayzen's primary legal owner across four core areas. You will operate as a trusted business partner - not just a gatekeeper - and are expected to move fast, apply sound commercial judgment, and help the business scale without unnecessary legal friction.

• Hands-on experience with contract drafting and commercial negotiations across a variety of agreement types
• Familiarity with cap table management and corporate governance in a VC-backed or founder-led company context
