People Operations Manager (m/f/d)

Hi 👋 I’m Tamta, Global People & Culture Lead at Kayzen and I’m looking for a People Operations Manager to join our People team in Berlin 🙌

If you enjoy building structure, creating great employee experiences, and keeping both HR operations and office life running smoothly — this might be for you.

Kayzen is a B2B SaaS platform that enables companies to run mobile in-app programmatic marketing in-house. In simple terms: we help companies automate the buying and selling of digital ads in real time — while giving them full ownership of their tech stack and performance data. That means more transparency, efficiency, and control. We’re an international, distributed team — with Berlin and Bangalore as one of our key hubs.

Based in Berlin (at least 3 days/week in-office),you’ll be the operational backbone of our People function -  ensuring smooth HR processes across the employee lifecycle while also helping maintain an organized, welcoming office environment. You'll partner closely with People, Finance, and leadership team to create a seamless employee experience from pre-onboarding to offboarding.

• Own HR processes across the employee lifecycle (pre-onboarding to offboarding)
• Prepare employment documents (offer letters, contracts, reference letters)
• Manage payroll input and collaborate closely with Finance team
• Maintain accurate, compliant, and confidential personnel records in our HRIS (Personio)
• Coordinate performance review and feedback cycles (via Leapsome)

• HR operations run smoothly and efficiently
• Payroll, documentation and reporting are always accurate and on time
• Employees feel supported throughout their lifecycle
• Our Berlin office remains an organized and welcoming space
• Processes are continuously improved, not just maintained

• Are based in Berlin and can work in-office at least 3 days per week
