- Build and maintain CI/CD pipelines to automate infrastructure testing and deployment.
- Develop and enhance Ansible playbooks and roles to improve network automation reliability and scalability.
- Support and mentor colleagues in software engineering methodologies and development practices.
- Drive innovation across network infrastructure management through automation and DevOps principles.
This is a unique opportunity to work with cutting-edge networking and automation technologies while making a direct impact on how network infrastructure is managed and evolved within a complex, highly secure environment.
If you have a strong software engineering background and meet most of the key requirements below, we'd encourage you to apply.
