OT Security Architect
Location: Hyderabad
Summary
The OT Security Architect is responsible for reviewing, assessing, and strengthening the security architecture of IT and Operational Technology (OT) solutions across on-premises, cloud, and integration environments. The role ensures that systems are designed and implemented according to security standards, hardening guidelines, and industry best practices. By supporting project teams during design and build phases, the OT Security Architect helps ensure secure implementation from the outset, while adapting controls to the unique operational constraints and risk profiles of OT environments. The position also contributes to improving technical documentation practices and promotes secure development principles throughout the lifecycle.
What You Will Do
Security Architecture Reviews
- Conduct Security Architecture Reviews for new and existing IT and OT solutions, including infrastructure, cloud (Azure), applications, and integrations
- Assess and validate security controls for solution architectures (authentication, logging, encryption, API security, secure integration patterns)
- Identify security risks and recommend mitigation measures to ensure solutions meet required protection levels before deployment
Project & Solution Support
- Provide security guidance to project teams during design and build phases, ensuring security-by-design principles are applied
- Review integrations and APIs to ensure secure data exchange and appropriate protection mechanisms for services and external connections
- Evaluate and recommend security measures tailored to operational constraints and risk profiles of OT environments
Secure Development Practices
- Provide guidance on secure coding principles and application security controls
- Promote secure handling of data within applications and services
- Support teams in adopting secure development practices across the lifecycle
Documentation & Collaboration
- Assist teams in producing clear and accurate technical architecture documentation, including diagrams
- Provide guidance, tools, or automation to improve documentation quality
- Collaborate with stakeholders to ensure security concepts are clearly communicated and understood
Critical Job Requirements
- OT Security Fundamentals: Understanding of industrial systems (ICS/SCADA) and their risks
- Security Architecture: Ability to design/review IT and industrial system architectures and identify security risks
- Network Segmentation: Expertise in securing boundaries between IT and OT environments using firewalls and secure connectivity
- Risk Assessment: Skilled in identifying risks while considering operational constraints and availability requirements
- Security-by-Design: Proven ability to integrate security controls early in solution design and adapt them to real-world operational limitations
- Cloud Security (Azure): Experience securing cloud services including access, network, and configuration management
- Identity & Access Management (IAM): Managing users, roles, permissions, and multi-factor authentication (MFA)
- Encryption & Data Protection: Protecting sensitive data at rest and in transit
What We Are Looking For
- Bachelor’s or Master’s degree in Computer Science, Information Security, IT, or related field (or equivalent experience)
- Strong experience in IT and OT security architecture across infrastructure, applications, and integrations
- Experience with cloud environments, particularly Microsoft Azure, and cloud security principles
- Knowledge of security controls for on-premises infrastructure (system hardening, network segmentation, identity management, logging)
- Experience reviewing integrations and APIs with secure authentication and data protection practices
- Understanding of application security and secure development principles
Skills
- Strong analytical and problem-solving skills for complex technical environments
- Ability to work autonomously and manage priorities across multiple reviews and projects
- Excellent written and verbal communication skills for technical and non-technical stakeholders
