• Participate in architectural discussions, influencing technical direction and strategy.
• Own the full development lifecycle - from technical design to deployment and monitoring.
• Troubleshoot production issues and support live operations when necessary.

• Strong understanding of AWS services including S3, Lambda, Redis, OpenSearch, API Gateway, EKS, and other cloud-native technologies.
• Excellent leadership, communication, and collaboration skills, with experience working in distributed, multicultural teams.
• Demonstrated ability to work independently and take ownership of deliverables in asynchronous work environments.

Preferred:

• Experience in custom development in Salesforce platform using Apex, LWC.
