• Hands-on experience with cloud environments (AWS preferred, especially ECS or similar services)
• Proven track record of owning and delivering features or initiatives end-to-end

• Strong problem-solving skills and ability to work independently
• Clear communication skills and ability to collaborate cross-functionally
