Summary

Reporting to the Global Head of IT Security, the Cybersecurity Lead - Product Security will act as the security architect and guardian for Celestica’s network hardware products and proprietary network operating systems. This role is distinct from enterprise IT security; you will embed security into the very fabric of the products we deliver to customers.
You will lead the adoption of "Secure by Design" principles, operationalizing the standardized Software Development Life Cycle (SDLC)  within product engineering teams. You will be responsible for translating high-level governance requirements into technical reality—ensuring our network switches, routers, and appliances are hardened against advanced persistent threats (APTs) and comply with Zero Trust principles.

Detailed Description

Performs tasks such as, but not limited to, the following:

• Secure Product Lifecycle: Lead the integration of security gates into the product development lifecycle for network hardware and OS software. Enforce the standardized SDLC policy and ensure threat modeling (using frameworks like STRIDE or PASTA) is conducted during the design phase of every new product release.

• Network OS Hardening: Direct the security hardening of the network operating system. Define and enforce baseline configurations to ensure the OS is resistant to tampering, implementing controls such as secure boot, kernel hardening, and restricted shell access.

• Application Security Testing: Orchestrate the "Standardizing Dynamic Testing and Vulnerability Management" initiative for product software.

• Oversee the implementation of Static Application Security Testing (SAST) using tools like Snyk in the CI/CD pipeline and establish a Dynamic Application Security Testing (DAST) framework to identify runtime vulnerabilities.

• Zero Trust Architecture: Architect product features that support Zero Trust environments. Ensure network products support granular micro-segmentation capabilities 12and robust identity integration, moving away from local authentication to centralized, MFA-ready administrative access.

• Vulnerability Remediation: Manage the product vulnerability lifecycle. Establish Service Level Agreements (SLAs) for remediating findings identified during penetration testing and DAST scans, ensuring no critical vulnerabilities ship to production.

   

• Crypto & Protocol Security: Ensure all product cryptographic implementations align with the "IT Encryption & Cryptography Policy", mandating AES-256 standards. Validate the security of implemented network protocols (BGP, OSPF, SSH, TLS) against industry best practices.

Knowledge/Skills/Competencies

• Threat Modeling: Mastery of threat modeling methodologies (STRIDE, PASTA) to identify design flaws early in the development cycle.

• Hardening: Expert knowledge of OS hardening standards (CIS Benchmarks, NIST) and how to apply them to custom hardware platforms.

•  

  Cryptography: Solid understanding of applied cryptography (PKI, TLS, AES, secure boot chains).
  Zero Trust: Ability to translate "Zero Trust" concepts 22 into concrete product features (e.g., API security, mutual TLS).

   

• Innovator: A proactive problem-solver who can balance security requirements with product performance and time-to-market constraints.

• Technical Authority: Capable of earning the respect of hardware engineers and kernel developers through deep technical competence.

• Detail-Oriented: Rigorous in validating that "Secure by Design" is not just a slogan, but a documented and tested reality.

Physical Demands

• Duties of this position are performed in a normal office environment.
• Duties may require extended periods of sitting and sustained visual concentration on a computer monitor or on numbers and other detailed data. Repetitive manual movements (e.g., data entry, using a computer mouse, using a calculator, etc.) are frequently required.

Typical Experience

• Product Security: 8–10 years of experience in product security, specifically focusing on network hardware (switches, routers, gateways) or embedded systems.
• Software Development: Strong background in C/C++, Go, or Python, with experience developing or securing Network Operating Systems (e.g., SONiC, Linux-based embedded OS).
• Network Architecture: Deep expertise in network protocols (L2/L3, TCP/IP, VLANs, VXLAN) and network security technologies (Firewalls, ACLs, 802.1X).
  AppSec Tooling: Proven experience implementing SAST/DAST pipelines (e.g., Snyk, Coverity, Burp Suite) and managing vulnerability disclosure programs.

Typical Education

• Education: Bachelor’s degree in IT, Networking, or a related field (equivalent experience accepted).
• Certifications: * Checkpoint: CCSE (highly preferred)
• General: CompTIA Security+ or Cisco CCNP Security.
