OT Security Engineer

Come Forge the Future of Machine Identity Security for Operational Technology & Industrial Control Systems

Where:
Tysons, VA (Hybrid)

At Corsha we're not just selling software; we're fundamentally reshaping how the most critical industrial and operational technology (OT) systems are secured. We're a cyber startup in the DC area, driven by a mission to bring trust, resilience, and identity to the operational systems that power our world – from factories to power grids. We're building the future of machine identity security, and we need a dynamic technical evangelist to join our front lines.

If you're an engineer who thrives on solving hard problems, isn't afraid to get your hands dirty with industrial control systems and sees the immense potential of cybersecurity in unconventional environments, then read on. We move fast, we build for impact, and we need a security visionary to help us secure the machines that matter most.

We’re looking for an OT Security Engineer to be a foundational engineer for our Machine Identity Platform (mIDP), specifically tailored for the unique and challenging landscape of OT systems. Your mission: implement, integrate, and defend the security infrastructure that underpins our cutting‑edge solutions, with a heavy emphasis on industrial control systems and OT networks.

This isn't just about keeping the lights on. It's about building security architectures that are inherently secure, highly available, and resilient against the most sophisticated threats, often in environments where traditional IT paradigms simply don't apply. You'll be bridging the gap between cutting‑edge cybersecurity technologies and the operational realities of factories, power plants, and critical infrastructure.

• Architect and Implement OT Security Solutions: Design, deploy, and manage secure architectures for our mIDP, specifically tailored for OT environments. This includes network segmentation, routing, switching, firewall configurations, and intrusion detection systems.
• ICS/OT System Integration: Be the subject matter expert for integrating our mIDP with industrial control systems. This involves understanding and working with common industrial protocols (Modbus, OPC UA) and architectures (e.g., Purdue Model).
• Machine Identity Integration: Collaborate closely with our product and engineering teams to integrate security configurations with our mIDP, ensuring seamless and secure authentication and authorization for OT devices and applications.
• OT Network Hardening: Implement and enforce robust security best practices, including vulnerability management and access control for OT networks.
• Troubleshooting and Optimization: Proactively monitor, troubleshoot, and resolve complex security issues across ICs and OT environments. Identify and implement optimizations to enhance system performance, reliability, and security.
• Automation and Tooling: Develop and implement automation scripts and tools (e.g., Python, Ansible) to streamline provisioning, configuration management, and operational tasks.
• Documentation and Knowledge Sharing: Create comprehensive documentation, runbooks, and contribute to internal knowledge sharing to ensure maintainability and scalability of our infrastructure.
• Stay Ahead of the Curve: Continuously research and evaluate new cybersecurity technologies, security trends, and best practices, particularly as they relate to OT and industrial control systems.
• Collaborate and Mentor: Work closely with cross‑functional teams (software engineers, security analysts, product managers) and provide mentorship to junior team members.

• 5+ years of intense experience in OT security or a related role with a proven track record in complex, high‑performance, and high‑stakes environments.
• Deep, demonstrable expertise in industrial control systems and OT environments – You've implemented security products and solutions in real‑world ICs/OT environments.
• Strong proficiency in network security principles – Firewalls, VPNs,…
