About the Role

People Operations Manager (m/f/d)

Berlin

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.

About Kayzen

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.

The Role

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.

Your Responsibilities & Impact

People Operations

  • 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)
  • Improve HR policies - because "that's how we've always done it" isn't good enough
  • Prepare regular and ad-hoc HR reports
  • Ensure compliance with German labor law and workplace regulations

Office & Culture

  • Act as the go-to person for Berlin office operations
  • Manage office supplies, vendors, and general administration
  • Organize company events, workshops, and team gatherings
  • Support workplace safety topics and external service providers

IT Coordination 

  • Manage equipment logistics for onboardings and offboardings for our global team
  • Coordinate user account setup and basic IT logistics
  • Liaise with external vendors when needed
  • You don't need to be an IT expert  - just the person who gets things sorted

What Success Looks Like

  • 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

You Might Be a Great Fit If You

  • Are based in Berlin and can work in-office at least 3 days per week
  • Have at least 2+ years of hands-on experience in People Operations / HR Generalist roles
  • Have experience in a fast-paced, international environment
  • Have experience automating processes and integrating AI into your daily workflow
  • Understand German employment law and HR best practices
  • Are structured, detail-oriented, and highly reliable
  • Communicate fluently in German and English
  • Enjoy taking ownership and working hands-on across HR and operations
  • Feel comfortable coordinating basic IT topics or external vendors
  • Hold a Bachelor's degree in HR or related fields

Why Join Kayzen?

  • Real ownership from day one
  • Direct access to top management and an extremely “visible” role
  • Exceptional career growth and learning opportunity
  • A fun, driven, and multinational team located across Germany, India, UK, Argentina, Ukraine, Spain  and many more countries
