• Compliance & Security

• Assist in implementing basic security measures to protect data and applications in multi-tenant environments, including encryption and access controls.

• Assist in the execution of remediation plans to address identified security gaps, under supervision.

• Support the creation and updating of documentation to ensure cloud infrastructure is in compliance with relevant industry standards and regulations.

• Automation & Change Management

• Assist in maintaining basic automation scripts and tools (e.g., Infrastructure as Code (IaC)).

• Adhere to change management plans for patching, updating, and rolling back applications, under guidance.

• Planning & Execution

• Track timelines with minimal supervision, ensuring work is completed in a timely manner and is in alignment with project requirements.

• Prioritize and adjust work as resources or timelines change, with some guidance.

• Collaboration & Partnership

• Collaborate within the team to better understand expectations and achieve shared objectives.

• Leverage a foundational understanding of business, stakeholder, and/or customer needs to build partnerships with limited guidance.

• Actively listen and ask questions to enhance collaboration.

• Build a basic understanding of business, stakeholder, and/or customer needs with guidance.

• Problem Solving

• Identify and address issues, escalating problems to senior staff as needed in accordance with standard procedures.

• Compile and review data and/or information from multiple sources to troubleshoot standard and non-standard errors.

• Continuous Learning

• Seek opportunities to gain knowledge and learn new skills and/or tools aligned with industry trends and best practices.

• Utilize feedback and training to improve skills.

• Participate in a culture of continuous learning and knowledge sharing.

• Continuous Improvement

• Implement updates to processes, protocols, and workflows to increase efficiency and effectiveness as directed, with some guidance.

• Contribute to ideation for future process improvements.
