Job Description

The OT Expert serves as the primary Operational Technology (OT) technical authority within the Customer Success organization, enabling customers, partners, and internal teams to maximize the value of Armis Centrix across complex industrial environments. 

This is an individual contributor role that partners closely with Technical Customer Success Managers (TCSMs), Product Management, Engineering, Sales, Support, partners, and customers to solve complex technical challenges, design scalable solutions, optimize customer outcomes, and influence the evolution of the Armis platform. 

Unlike traditional deployment or professional services roles, the OT Expert is engaged when deep technical expertise, sound engineering judgment, and strategic guidance are required. Whether recovering a struggling implementation, redesigning an architecture, solving complex visibility challenges, advancing a customer’s OT maturity, or influencing future product capabilities, the OT Expert is the trusted technical advisor for the organization’s most challenging customer engagements. 

Success in this role is measured not by the number of implementations completed, but by the ability to solve complex problems, enable customer success, and maximize the long-term value customers realize from Armis Centrix.

• Help customers evolve from initial implementation toward mature, strategic adoption of Armis across their OT ecosystem

Enable Customer Success Through OT Expertise

• Advise customers on how Armis capabilities support OT and industrial initiatives, including asset discovery, lifecycle management, network segmentation, risk management, security posture, process monitoring, and compliance

• Mentor internal teams on technical knowledge, architectural best practices, troubleshooting methodologies, and field lessons learned
• Raise the overall technical capability of the Customer Success organization

Influence Product Innovation

• Act as the voice of the customer within Product Management and Engineering
• Identify product limitations, capability gaps, and emerging industry requirements through direct engagement with complex OT environments
• Collaborate on roadmap priorities and ensure platform enhancements address real-world customer needs

Advance Technical Excellence

• Develop reusable architectural guidance, implementation frameworks, troubleshooting playbooks, technical documentation, and best practices
