Legal Counsel; m​/f

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.

Kayzen is an App demand-side platform (DSP) dedicated to democratizing app advertising on Mobile and Connected TV devices. We enable leading apps, agencies, media buyers, and brands to run programmatic customer acquisition, retargeting, and brand performance campaigns through our self-serve and managed service options. Built on the three core pillars of performance, transparency, and control, Kayzen powers the world's best performance marketing teams with bespoke solutions that fuel business growth and deliver a competitive advantage.

With an unprecedented scale of 300B+ daily ad requests from 1.6B+ unique users worldwide, we serve up to 1B+ ads per day in 180 countries. Kayzen is accessible through our APIs and user interface.

You will join a small, senior team and work directly alongside our Finance & Legal Lead. Your key stakeholders will be the leadership team, as well as our Finance, Operations, and Commercial functions across a globally distributed organisation.

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.

• Manage and maintain Kayzen's cap table
• Oversee corporate governance across Kayzen's group structure, including subsidiary management, shareholder resolutions, and notarial filings under German law
• Support fundraising and investor relations from a legal and corporate perspective

• Further develop and scale Kayzen's compliance framework to match our growth as an internationally operating company
• Monitor relevant regulatory developments (ad-tech, data privacy, employment, corporate) and translate them into actionable guidance for the business

• Qualified lawyer („Volljurist“) or Business lawyer („Wirtschaftsjurist“) with 2-5 years of relevant professional experience
• Strong understanding of German business law is essential; additionally solid understanding of international and US legal frameworks, particularly in the context of data privacy and commercial contracts
• Strong knowledge of GDPR and European data protection law; familiarity with US privacy regulations (CCPA etc.) a strong plus
• Experience in a start-up or scale-up environment is strongly…
