Job Title: Principal IT/OT Security Architect Manufacturing Sector Location: Bangalore Division: Industrial Security, Automation & Network Modernization Level: Principal Engineer Secure What Moves the World and Automate It Americas manufacturing sector isnt just under pressure from cyber threats its being pushed to modernize faster than ever. At Surya Technologies , were not just defending factories. Were helping them transform , using automation, intelligent observability, and solutions-as-code to bring repeatability and resilience to industrial environments. Were hiring a Principal IT/OT Security Architect to lead the charge in converging cybersecurity, networking, automation, and compliance across mid-market and enterprise manufacturers in the Southeast. This isnt a clipboard-and-checklist kind of role. You’ll build solutions that scale — powered by code, infused with AI-driven observability, and designed to run on the plant floor with the same reliability as a CNC machine. What You’ll Do Architect converged IT/OT security solutions that are scalable, secure, and automation-ready Use infrastructure-as-code (IaC) principles to define network, sensor, and control plane configurations — versioned, peer-reviewed, repeatable Integrate AI-powered observability platforms like Datadog or Defender for IoT for anomaly detection and visibility Lead zero trust architecture projects for OT — combining microsegmentation, NAC, and managed detection Build automated compliance frameworks for CMMC, NIST 800-171, and IEC 62443 — transforming audits from nightmares into workflows Develop standard deployment patterns that enable your work to scale across 50+ factories Partner with Surya’s automation and platform engineering teams to build tools, APIs, and templates that replace manual configuration Represent Surya in technical conversations with CIOs, plant engineers, and auditors — helping each group understand the mission in their own language Serve as the technical backbone of the manufacturing practice, mentoring future engineers and shaping go-to-market solutions What You Bring 7+ years in cybersecurity, industrial networking, or automation architecture Experience in designing and deploying secure industrial networks — VLANs, firewalls, switches, segmented zones Proficiency in tools like Claroty, Defender for IoT, Nozomi , and Tenable.ot Comfortable writing and reviewing YAML, Terraform, or Ansible playbooks for infrastructure or security automation Familiar with using AI/ML tools or anomaly detection engines in monitoring pipelines Strong understanding of compliance frameworks (CMMC, NIST, ISO, IEC 62443) and how to translate them into codified technical controls Passion for turning security into a platform , not just a service — if you’ve ever turned an SOW into a repo, you belong here Comfortable in a hard hat and a hoodie — you can talk to both an OT technician and a CISO Why This Role Matters Manufacturing is entering its most vulnerable — and most transformative — decade. AI, automation, and security are colliding on the factory floor, and someone has to build the playbook for how it all works together. That someone is you. This role is your opportunity to be the architect behind secure, smart, and scalable factories , not just protect the status quo. You’ll design systems once and deploy them dozens of times — with repeatability, resilience, and intelligence baked in from day one. Why Surya Surya is a next-generation managed services firm built for industrial modernization . We help manufacturers go from legacy to leading edge — combining cloud platforms, security, observability, and AI-driven automation. We’re growing rapidly in the Southeast and building a team of the best technical minds in the region. You won’t be buried in bureaucracy here — you’ll be building the standard others follow. Join Us If you’ve ever said, “There has to be a better way to secure and scale factory environments” — you’re right. Now help us build it. Apply now — and lead the future of manufacturing security, one intelligent deployment at a time.
