Job Introduction
The Frequentis Group is an international supplier of communication and information systems for control centres with safety-critical tasks.

In Cluj we started in 2009 and our local team currently has 250+ colleagues and is growing.

- As a power user and maintainer of 3rd party services, continuously measure and improve the performance to enable scaling the whole system to serve large air traffic control centers with hundreds of operator positions.
- Design, implement and maintain automation solutions for deployment, configuration and verification of the MosaiX infrastructure and auxiliary layers.
- Continuously extend, improve and integrate components using CI/CD best practices and IaC (Infrastructure as Code), to implement lifecycle updates and security fixes on a regular basis.
- Support product development teams migrating their applications to the MosaiX platform, ensuring alignment with the intended platform design and principles.
Key Qualifications
- Deep knowledge of Linux and container technologies (Docker)
- Hands-on experience with Ansible (Puppet experience is a plus)
- Knowledge of scripting languages such as Python and Bash and/or experience in building software solutions using other programming languages
- Experience in software engineering practices like test-driven-development (TDD) to ensure high-quality software
