• \tPerform hardware-software integration testing and validation

• \tCreate and conduct comprehensive unit and integration system test cases

• \tPerform impact analysis for change request (e.g. sensor upgrade with additional parameters)

• \tCreate and maintain documentation for hardware setup, configuration, and troubleshooting procedures

• \tDevelop, and deploy backend cloud services in both serverless and serverful architecture

• \tManage and update infrastructure and oversee the management and maintenance of backend resources

• \tSet up secure role-based access controls

• \tSet up system monitoring and alerts, with notifications via short messaging or email

• \tPerform ongoing code maintenance and develop new features to enhance functionalities for the users

• \tDesign and develop frontend for IoT data transformation solutions connecting with backend services

• \tDevelop and maintain API documentation using OpenAPI

• \tTroubleshoot and resolve system issues as they arise to ensure system reliability

• \tEnhance system performance for speed, scalability, and cost-effectiveness

• \tApply cybersecurity measures for system hygiene and data protection
