About Digitalis Technologies

Digitalis Technologies (DT) is an enterprise technology and consulting company focused on ERP implementation, custom business applications, integrations, automation, and technology support.

As our customer deployments and infrastructure footprint grow, we are looking for a hands-on DevOps & Cloud Infrastructure Engineer who can take ownership of production infrastructure, deployments, databases, backups, migrations, monitoring, security, and system reliability.

Role Overview The DevOps & Cloud Infrastructure Engineer will be responsible for managing Linux-based production environments and supporting development teams in deploying and maintaining business-critical applications.

The role requires robust practical knowledge across infrastructure and application operations, including Linux, cloud platforms, databases, web servers, APIs, monitoring, automation, deployments, and troubleshooting.

- Write and maintain Bash/Shell scripts.
- Use Python for infrastructure automation and operational utilities where appropriate.
- Automate backup, deployment, migration, monitoring, and housekeeping activities.
