$130,000.00/yr - $130,000.00/yr OT/ICS Security Specialist
We are seeking a highly skilled OT/ICS Security Specialist to lead and enhance the security posture of our Operational Technology (OT) and Industrial Control Systems (ICS) environments. This role is critical in ensuring the integrity, availability, and confidentiality of industrial networks, protecting critical infrastructure, and implementing robust cybersecurity strategies tailored to the unique needs of our industrial environments. The focus of the position is to assess risk, remediate risk, and mitigate risks. Primary Duties & Responsibilities
This is a hands-on role that involves administering and implementing solutions, planning strategically, and resolving issues as they arise — all while maintaining sensitivity to plant and distribution center operations. Develop, implement, and oversee OT/ICS security strategies that align with business goals and meet industry standards and regulatory requirements. Lead risk assessments, manage vulnerabilities, and conduct security audits across operational technology systems. Collaborate with engineering, IT, and operations teams to integrate cybersecurity best practices into servers, PCs, SCADA, DCS, PLCs, and other industrial control systems. Monitor for cybersecurity threats, incidents, and anomalies impacting industrial assets, and coordinate appropriate response actions. Create and maintain OT security policies, procedures, and training programs to build awareness and strengthen security practices. Work closely with the CIO/CISO, VP of Operations, and Director of Engineering — teamwork and collaboration are critical to success in this role. Review existing architectures, identify security gaps, and recommend prioritized improvements with a risk-aware approach. Partner with external vendors and consultants to evaluate and implement new security technologies and solutions. Ensure security initiatives align with frameworks such as NIST CSF, ISA/IEC 62443, CIS Controls, and MITRE ATT&CK for ICS. Lead incident response efforts for OT-related breaches, including forensic investigations and corrective action planning. Collaborate cross-functionally to audit and test networks, servers, and OT/ICS equipment to ensure system integrity and security. Qualifications
Bachelor's or Master's degree in Cybersecurity, Computer Science, Industrial Engineering, or a related field. 5+ years of cybersecurity experience, with at least 3 years specifically focused on OT/ICS environments. Strong networking background. In-depth knowledge of SCADA, PLCs, DCS, HMIs, IIoT, and industrial network protocols such as Modbus, DNP3, OPC-UA, and BACnet. Hands-on experience with firewalls, IDS/IPS, network segmentation, and endpoint protection in OT environments. Strong analytical skills in threat detection, vulnerability management, and incident response. Excellent communication skills, with the ability to collaborate effectively with both technical and non-technical teams. Preferred Qualifications
Familiarity with risk management methodologies and compliance standards such as NERC CIP, ISO 27001, GDPR, and CISA guidelines. Relevant certifications preferred: CISSP, GICSP, GRID, CISM, ISA/IEC 62443 Expert. The ability to strategize, document, and implement business continuity and disaster recovery. This is a W2 role only. This is not subvendor friendly. Please only serious applicants. EEO Statement : All qualified applicants will receive consideration for employment without regard to race, color, national origin, age, ancestry, religion, sex, sexual orientation, gender identity, gender expression, marital status, disability, medical condition, genetic information, pregnancy, or military or veteran status. We consider all qualified applicants, including those with criminal histories, in a manner consistent with state and local laws, including the California Fair Chance Act, City of Los Angeles' Fair Chance Initiative for Hiring Ordinance, and Los Angeles County Fair Chance Ordinance. For unincorporated Los Angeles county, to the extent our customers require a background check for certain positions, the Company faces a significant risk to its business operations and business reputation unless a review of criminal history is conducted for those specific job positions.
