Whatyou'll doAs Niron's
Senior Manager, IT Security, you will own the design, implementation, and ongoing operation of the cybersecurity programs that protect our data, systems, tools, and facilities. You will also serve as Niron's Facility Security Officer (FSO), owning our regulatory security governance and compliance obligations. This role safeguards operational technology (OT) and information technology (IT) environments in a high-growth, advanced manufacturing setting.
This is a working leadership role: you will own the program and remain hands-on-keyboard. You will personally administer core security tools, monitor systems, and respond to incidents, while setting the policies, standards, and procedures the rest of the company follows. You will collaborate across IT, OT, Facilities, and business units, and communicate effectively with stakeholders at all levels. It is not a purely strategic role, nor a purely tactical one as you are the person who both builds the program and administers the tools and environment.
