Principal OT Product Security Architect​/Midtown​/Hybrid

This established global technology and industrial automation organization is looking for a Principal OT Product Security Architect to help secure complex automation products and solutions used in modern warehouses, distribution centers, and supply chain operations. This full-time opportunity is based in Atlanta, GA, with a hybrid work environment and a focus on operational technology (OT), industrial control systems (ICS), product security, and cloud-connected infrastructure.

This is an opportunity to take a lead role in shaping product security architecture across hardware, software, robotics, industrial networks, and connected systems. You’ll work closely with engineering, product management, R&D, and security leadership to embed security into products from initial design through deployment and ongoing support. If you enjoy solving complex security challenges, influencing technical decisions, and building secure‑by‑design practices across a global organization, this role offers the opportunity to make a meaningful impact.

• 8 years of experience in cybersecurity, OT/ICS security, product security, network security, systems engineering, or a related field.
• Demonstrated experience designing, implementing, or assessing OT cybersecurity architectures.
• Experience in industrial automation, robotics, warehouse automation, manufacturing, industrial control systems, or similar operational technology environments.
• Strong understanding of OT/ICS architecture, industrial networking, PLCs, HMIs, SCADA, firewalls, network segmentation, VPNs, and secure remote access.
• Experience securing complex hardware, software, embedded systems, and integrated technology solutions.
• Knowledge of threat modeling, attack‑surface assessments, penetration testing, vulnerability management, and risk‑based remediation.
• Familiarity with Windows/Linux, networking, cloud environments, and scripting or automation using Python or Power Shell.
• Knowledge of cybersecurity frameworks and standards such as IEC 62443, NIST CSF, NIST SP 800-82, ISO 27001, or the EU Cyber Resilience Act.
• Ability to translate cybersecurity risks and regulatory requirements into practical architecture decisions, engineering requirements, and security controls.
• Strong communication, technical documentation, consulting, and stakeholder management skills.
• Ability to influence engineering and business teams without direct authority.

• Define and maintain OT cybersecurity architecture, technical requirements, security standards, and reference architectures for industrial products and solutions.
• Lead security architecture reviews across operational technology, software, controls engineering, networking, and cloud‑connected environments.
• Design and evaluate secure network architectures, including segmentation, industrial DMZs, firewalls, secure remote access, and OT‑to‑cloud connectivity.
• Integrate secure‑by‑design principles and Dev Sec Ops  practices throughout the product development lifecycle.
• Establish cybersecurity requirements for products, embedded components, software, industrial systems, and customer deployments.
• Lead or support threat modeling, vulnerability assessments, penetration testing, and security architecture evaluations.
• Develop risk‑based vulnerability remediation strategies that account for operational availability, reliability, and safety requirements.
• Define OT security monitoring requirements and support integration with customer security operations environments.
• Translate applicable security frameworks and regulations into actionable engineering controls and technical requirements.
• Support product certifications, conformity assessments, audits, and customer security reviews.
• Conduct OT cybersecurity…
