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 DevOps Engineer to define and lead our DevOps strategy across embedded Linux and bare‑metal firmware environments.

You will design scalable CI/CD pipelines, automate build and test workflows, and integrate modern DevOps practices to accelerate development cycles and improve product quality.

This is a key role bridging embedded systems with advanced automation.

Key Responsibilities

• 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, GitLab 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 DevOps best practices across the organization.
• Promote automation and infrastructure‑as‑code principles to improve efficiency and scalability.
• Implement secure DevOps practices, including credential management and artifact signing.
• Support compliance standards (e.g., ISO 26262, IEC 62304) through traceable, audit‑ready pipelines.

Qualifications

• Proven experience with CI/CD for embedded Linux (Yocto) and bare‑metal systems.
• Expertise in cross‑compilation toolchains, linker scripts, and bootloader 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, GitLab CI, and containerization (Docker).

Preferred Qualifications

• 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).
