Assist with AWS access management, security configurations, resource tagging, and infrastructure hygiene.

Support basic cloud cost monitoring and optimization initiatives.

Help maintain reliable connectivity between on‑premises systems and AWS environments.

Security & Compliance

Monitor infrastructure and security alerts and assist in investigating potential security incidents.

Support vulnerability remediation, system hardening, patch management, and secure configuration activities.

Assist with identity and access controls, endpoint protection, and security compliance requirements.

Participate in audit preparation, data protection, privacy, and information security initiatives.

Escalate security or infrastructure incidents based on their severity and business impact.

Backup, Recovery & Documentation

Assist with backup monitoring and validation, redundancy checks, recovery procedures, and disaster recovery activities.

Maintain accurate documentation covering infrastructure configurations, network diagrams, incidents, changes, and troubleshooting procedures.

Follow established change, release, and configuration management processes when implementing infrastructure changes.

Keep technical records current and ensure operational procedures are properly documented.

Work with internal IT teams, business stakeholders, vendors, and service providers to resolve technical issues.

Provide secondary support across another infrastructure area when the primary technical owner is unavailable.

Communicate incident status, risks, blockers, and resolution progress to relevant stakeholders.

Provide onsite technical assistance when required for critical infrastructure activities.

Participate in on‑call or after‑hours support for urgent infrastructure concerns.
