Staff Engineer, Automation Script Specialist Job Details | Celestica International LP

Celestica is a technology leader dedicated to driving customer success and market advancements. They are seeking an experienced network automation script specialist to create an automation script framework for integrating into existing software development pipelines, optimizing the verification phase of the product SDLC process using AI.

Responsibilities:

• Create an automation script framework that enables the development of new automation scripts that can seamlessly integrate into existing software development pipelines to intelligently verify PR code changes
• Analyze existing network automation scripts and develop a list of automation script enhancements to optimize the verification phase of the product SDLC process
• Use AI to design, develop, and enhance new and existing automation scripts
• Integrate agentic AI workflows into automation scripts to provide test failure problem determination and suggest possible remediations
• Collaborate with the larger DevTestOps Team and software development teams to build an immersive, intuitive, robust, and full-featured control center for managing and operating worldwide network automation test infrastructure
• Ensure the control center provides services to engineers to assist with debugging and retesting updated scripts

Requirements:

• Proven experience building complex automation script frameworks using extensive sets of common libraries
• In depth experience running, triaging, and debugging automation scripts
• Familiarity with high-performance networking environments, specifically SONiC, OpenBMC, and data center hardware management
• Practical experience integrating AI agents or LLM-based workflows into software applications to automate decision-making and analysis
• Deep understanding of test-driven development (TDD), CI/CD pipelines, and robust software engineering practices
• Ability to bridge the gap between cloud-hosted software and physical hardware distributed across global sites
• Lead the design and implementation of a robust, automation script framework that enables AI to quickly create new automation scripts that will run within a confederation of Automation Testbeds
• Maintain and enhance existing automation scripts to maintain hardened execution reliability
• Integrate agentic AI workflows to automate resolution of script failures
• Analyze script failures to identify software components that are below accepted reliability standards
• Work closely with DevTestOps and software development teams to ensure the control center provides services to engineers to assist with debugging and retesting updated scripts
• Understanding of L2/L3 protocols (STP, BGP, OSPF, VLANs, VXLAN), port features (LLDP, MLAG, and ACLs), network services (SNMP, DHCP, DNS), and network security (SSL, DoS)
• Hands-on experience with high-performance traffic generators, specifically IXIA (IxNetwork/IxLoad) or Spirent
• Familiarity with using and configuring IXIA, network switches, and network servers
• Mastery of Python (the industry standard for network automation) and its testing frameworks (PyTest, Robot Framework)
• Experience integrating automation scripts into Azure DevOps or BitBucket Pipelines
• Ability to move beyond 'linear scripts' to build modular, reusable automation scripting framework that can evolve with AI advancements
• The ability to audit legacy scripts and identify specific 'technical debt' to be replaced by AI-driven optimizations
• Ability to speak the 'language' of both hardware network engineers and cloud software developers
• Capacity to see the 'Test Automation Control Center' as a holistic product rather than a collection of isolated scripts
• To connect cloud-hosted control applications with on-prem physical hardware
• Familiarity with hosting automation controllers in environments like AWS, Azure, or GCP
• Advanced knowledge of Linux environments for switch management and script execution
• This role operates at the intersection of high-speed networking and modern cloud software
