About this job

Nozomi Networks is a leader in OT and IoT cybersecurity, defending large organizations, critical infrastructure, and government entities across multiple countries using an AI-powered platform. As the company expands, its Delivery department is hiring a Technical Support Engineer for a fully remote position in India. In this role, you will be part of a team dedicated to securing vital operational technology and internet of things environments. A normal day involves delivering post-sales support, troubleshooting and resolving technical problems, replicating customer issues in a lab setting, collaborating with internal product and engineering groups, and providing exceptional customer service. You will also help maintain core product knowledge, write knowledge base articles, and offer white-glove assistance to critical accounts. This fully remote job requires a dedicated home office setup with reliable power and internet connection, allowing you to work autonomously while helping protect critical infrastructure from cyber threats.

• Deliver post-sales break-fix support and consulting to resolve technical issues.
• Provide customer service for infrastructure design, deployment, testing, verification, and optimization.
• Interact with customers to fix issues and coordinate with internal Product and Engineering teams.
• Replicate and reproduce customer problems in a lab environment before internal escalation.
• Write new knowledge base content and update existing documentation.
• Offer white-glove treatment and understand critical account technical environments.

Requirements

• Proven experience in customer-facing Technical Support or Systems Engineer roles.
• Background in network security through support, design, consultancy, or operations.

• Familiarity with common networking, security protocols, and applications.
• Technical experience installing, configuring, and operating security appliances in complex environments.
• Strong understanding of information security principles and excellent troubleshooting abilities.

Who should apply

This role suits professionals with a solid background in network security, Unix systems, and customer-facing technical support. Ideal candidates possess strong troubleshooting capabilities, knowledge of security appliances, and familiarity with virtualization and API integrations. It is a great fit for individuals who can work autonomously in a fully remote setup requiring a dedicated home office with reliable power and internet. Because the posting mentions technical support experience is a plus but not strictly mandatory, candidates with relevant systems engineering or security operations backgrounds are also encouraged to apply.
