Required Skills

- A minimum of 4 years' progressive experience in OT, ICS, or IoT security, or in network security with OT exposure
- A minimum of 6 years' progressive experience, including hands-on OT asset visibility platform delivery
- Position-specific requirements: hands-on deployment experience with Armis is strongly preferred; equivalent depth on another OT visibility platform (Claroty, Nozomi Networks, Dragos,



Cisco Cyber Vision) with demonstrated ability to convert quickly will be considered. Armis certification is preferred, alongside an OT security credential such as GICSP, ISA/IEC 62443 Cybersecurity Specialist, or equivalent. Experience in logistics, warehousing, manufacturing, or utilities environments, and comfort with occasional regional travel to client sites, is an advantage.

- Hands-on expertise with Armis Centrix or an equivalent OT and IoT asset visibility platform, including collector architecture, integrations, and policy tuning.
- Solid understanding of OT and ICS environments, the Purdue reference model, and the availability and safety constraints that govern change in operational environments.
- Working knowledge of industrial and building protocols such as Modbus, DNP3, BACnet, EtherNet/IP, PROFINET, and S7, and how they behave on the wire.
- Solid network engineering fundamentals: switching, VLANs, routing, SPAN and TAP design, firewalls, and network segmentation approaches.
- Familiarity with OT security frameworks and standards including IEC 62443, NIST SP 800-82, and the NIST Cybersecurity Framework.
- Ability to bridge IT security and OT engineering stakeholders, who typically have different priorities, vocabulary, and risk tolerance.
- Excellent communication and engagement skills; ability to communicate with all levels of management and to explain OT risk in business terms.
- Ability to generate creative solutions to difficult or ambiguous problems in environments where standard IT security controls cannot be applied.
- Proficiency with Microsoft PowerPoint, Excel, and Visio for design documentation and client reporting.
- The ideal candidate is a supportive, positive, self-driven, and growth-oriented individual with a consulting mindset and credibility on a plant or facility floor.
