Your Tasks

Focus on the research, development, and testing of software components that support a sustainability-across-the-stack approach. Work within an open-source environment to create innovative orchestration solutions that enhance energy efficiency and reduce the environmental impact of distributed computing systems.

This role involves implementing sustainable practices throughout the entire technology stack—from virtualization and infrastructure to application development and Edge IoT setups, including sensors and other IoT devices.

  • Research and Development of Sustainable Software Components: Develop software components that contribute to energy-efficient orchestration within the Edge-Cloud ecosystem. Implement and test new features that prioritize sustainability, ensuring they meet performance and efficiency goals
  • Open-Source Programming: Engage with the open-source community to share findings, collaborate on new ideas, and integrate community feedback. Document and share code, tools, and best practices to foster a collaborative environment for sustainability-focused development
  • Testing and Validation: Use benchmarking tools and metrics to measure the energy consumption and environmental impact of software across the stack. Continuously optimize software based on testing results, aiming for highest levels of sustainability and performance
  • Sustainability-Across-the-Stack Implementation: Work with cross-functional teams to ensure sustainability is integrated across all layers of the software stack, from application code to infrastructure management. Develop and implement orchestration strategies that optimize resource allocation, workload distribution, and energy consumption. Identify and address sustainability challenges at each level of the stack, including virtualization, infrastructure, application development and Edge IoT setups
