• Familiarity with UML, TOGAF or similar architecture methodologies.
• Experience working with AWS, Azure or Google Cloud.
• Experience coordinating technical workstreams in distributed international teams.

You do not need to meet every nice-to-have requirement. We are also interested in candidates with strong architecture experience who would like to deepen their knowledge of IoT connectivity platforms.
