On an international team, the first thing colleagues need from you is a clear, confident introduction: who you are, what you work on, and how you fit into the team.

Example: "I'm the backend engineer on the payments team. I mostly work on our API and the integration with the mobile app. Happy to be looped in on anything touching checkout."

Keep it short — one or two sentences on your role, one on what you're currently focused on. Save the detail for when someone asks.
