OT Architect
Direct Hire
Austin or Temple, TX
Hybrid - 2-3 days on site

We are seeking a highly skilled IoT/OT Security Architect to play a critical role in protecting and enabling our industrial, operational, and connected technology environments. In this role, you will design and govern secure-by-design architectures that supports Industrial Control Systems (ICS), Operational Technology (OT), and Internet of Things (IoT) platforms-balancing cybersecurity risk reduction with operational reliability, safety, and uptime.
You will serve as a trusted technical authority and partner to cybersecurity, engineering, facilities, and operations teams, helping the business securely adopt and scale connected technologies while aligning with industry frameworks, regulatory expectations, and business objectives. This is an opportunity to shape how security is embedded into critical systems that power the organization.
This is a hybrid position which will require the candidate to report and work from the office at least three days a week. Therefore, interested candidates should be within a 50-minute radius from Temple, TX.
Benefits you can count on:

• Day 1 Benefits: medical, dental, and vision insurance, FSA/HSA, and company-paid life insurance
• Paid time off begins day one.
• 401(k) Profit Sharing Plan after 90 days.
• Additional benefits: pet insurance, maternity/paternity leave, employee assistance programs, discount programs, tuition reimbursement program, and more!

What You'll Do

• Design, implement, and maintain secure IoT and OT security architectures, including reference models, standards, and architectural patterns supporting ICS, building systems, and connected devices.
• Define and implement OT network segmentation strategies, including zones, industrial DMZs, and micro-segmentation, to separate IT, OT, and IoT environments in alignment with risk tolerance and best practices.
• Establish and maintain visibility of IoT and OT assets-controllers, sensors, embedded systems, and industrial endpoints-to support risk assessments, vulnerability management, and lifecycle governance.
• Conduct OT/IoT-focused risk assessments and threat modeling, identifying cyber, safety, and operational risks and recommending appropriate mitigating or compensating controls.
• Partner with vulnerability management teams to prioritize and remediate OT/IoT vulnerabilities using passive monitoring, approved scanning approaches, and risk-based strategies.
• Support the design and integration of OT threat detection, monitoring, and logging, and provide subject matter expertise during incident response activities involving industrial systems.
• Collaborate closely with IT, OT operations, engineering, facilities, vendors, and cybersecurity teams to review designs, assess new technologies, and provide security guidance for OT and IoT initiatives.
• Develop and maintain architecture documentation, security standards, trust zone models, and data flow diagrams, continuously evaluating emerging threats and technologies to strengthen the organization's security posture

What We're Looking For

• Bachelor's degree in Computer Science, Cybersecurity, Engineering, Information Systems, or a related technical field-or equivalent hands-on experience securing enterprise or industrial environments.
• 3-5+ years of progressive experience in cybersecurity, network/security architecture, or infrastructure engineering, with direct responsibility for securing IoT, OT, or ICS environments.
• Demonstrated experience designing and governing OT security architectures, including industrial DMZs, network segmentation, firewall policy design, traffic allow-listing, and secure remote access for vendors and operations teams.
• Strong understanding of trust boundaries and data flows between IT, OT, and IoT environments, with the ability to secure integration without disrupting availability or safety.
• Working knowledge of OT-specific risk considerations, such as legacy systems, limited patching windows, safety impacts, and lifecycle constraints, and the ability to design compensating controls where traditional IT approaches are not feasible.
• Excellent architectural communication skills, including the ability to create and review diagrams, lead or participate in design reviews, and influence stakeholders across technical and non-technical teams.
• This position requires the ability to read, write, and understand English at a level sufficient to perform job-related tasks effectively and safely. This includes understanding work instructions, safety protocols, and communications essential to the role. The requirement is directly related to the nature of the job and ensures compliance with workplace safety and operational standards.
