Polatis is a leader in all-optical network switching technology, delivering cutting-edge solutions to global customers.
Our Product Software Team develops customer-facing software for our industry-leading optical switches, managing two distinct software stacks:

• Network Software (NIC SW):
Implements L2/L3 protocols and interfaces (TL1, Netconf, Restconf, WebUI).

• Control Software (DSP SW):
Bare-metal stack controlling piezoelectric actuators for precision optical switching.
We are seeking a Senior Dev Ops Engineer to define and lead our Dev Ops strategy across embedded Linux and bare-metal firmware environments.
You will design scalable CI/CD pipelines, automate build and test workflows, and integrate modern Dev Ops practices to accelerate development cycles and improve product quality.
This is a key role bridging embedded systems with advanced automation.

Key Responsibilities of the Senior Dev Ops Engineer role:

• Design, implement, and maintain CI/CD pipelines for Yocto-based Linux and bare-metal firmware projects.

• Automate build, test, and deployment processes, including hardware-in-the-loop (HIL) testing.

• Integrate static analysis, unit testing, and monitoring into automated workflows.

• Manage and optimize build infrastructure using Jenkins, Git Lab CI, and custom scripts.

• Ensure reproducible Linux builds with Yocto, including kernel and BSP layer maintenance.

• Develop containerized environments (Docker) for consistent build and test processes.

• Collaborate with development, QA, and IT teams to embed Dev Ops best practices across the organization.

• Promote automation and infrastructure-as-code principles to improve efficiency and scalability.

• Implement secure Dev Ops practices, including credential management and artifact signing.

• Support compliance standards (e.g., ISO 26262, IEC 62304) through traceable, audit-ready pipelines.
In order to be successful in this role you must have:

• Proven experience with CI/CD for embedded Linux (Yocto) and bare-metal systems.

• Expertise in cross-compilation tool chains, linker scripts, and boot loader integration.

• Strong Python and shell scripting skills for automation.

• Hands-on experience with secure code signing and HSM integration.

• Familiarity with hardware-oriented test automation (flashing, UART, board resets).

• Proficient in Jenkins, Git Lab CI, and containerization (Docker).
It would be great if you had:

• Knowledge of Kubernetes for scalable test environments.

• Exposure to cloud platforms (AWS, Azure, GCP) for CI/CD and remote testing.

• Experience with security and performance testing tools (Nessus, JMeter, Locust).
