  • Lead communication within the organization on long running initiatives to improve or unify the API Design, and ensure they get adopted successfully
  • Closely collaborate with the Head Of Product and Staff Engineers of the Experience & Extensibility group
  • Evolve and promote our tech vision internally

What you need to succeed:

  • A technical background with a proven track record as an individual contributor (5+ years)
  • 2+ years of experience in a technical leadership or architect role
  • Experience working on API Design, ideally for multi-tenant SaaS products
  • Experience with UX Research and Design techniques, and applying them to APIs

  • Ability to live up to commercetools’ defined leadership values 
  • Great self-assessment mastery
  • Experience working within an Agile environment with focus on the customer view

Nice to have:

  • General experience with our tech stack: HTTP, Rest APIs, GraphQL, OAuth, RAML, Postman
  • General experience within the e-commerce space
