Learning how to conduct basic security checks, vulnerability assessments, and system hardening.

Supporting automation efforts using tools such as Ansible, Terraform, or CI/CD pipelines.

Troubleshooting issues across Linux, Windows, containers, and cloud environments.

Helping ensure documentation is clear, accurate, and up to date.

Learning and applying DevOps and SRE best practices.

Collaborating with and learning from senior team members.

Essential Skills / Experience 

Understanding of Linux or Windows operating systems.

Some experience with scripting (Bash, Python, PowerShell, etc.) — even from personal projects or coursework.

Interest in automation and DevOps tools (Ansible, Terraform, CI/CD, Git).

Exposure to cloud platforms such as Azure, AWS, or similar (hands‑on or theoretical).

Strong problem‑solving mindset and willingness to experiment.

Eagerness to learn new technologies and work in a fast‑paced environment.

Good communication skills and ability to work well in a team.

Desirable Skills

These are things you can learn on the job, but having some exposure is a bonus:

Understanding of Infrastructure as Code (IaC) concepts.

Awareness of security best practices.

Experience with containers (Docker, Podman) or Kubernetes.

Familiarity with GitLab, JIRA, Confluence, or similar tools.

Basic knowledge of monitoring tools (Nagios, Splunk, Prometheus, etc.).

Experience with automation or configuration management.

Understanding of Agile or DevOps principles.
