About AHEAD

AHEAD helps organizations modernize and secure the technology that runs their business. We are building a deeper Operational Technology capability for clients in manufacturing, energy, utilities, healthcare, transportation, and other industries where uptime, safety, and resilience matter.

The Role
The Principal Technical Consultant, Operational Technology is a senior technical leader and trusted advisor, and the primary technical resource on OT Assessments and SRDP (strategy, roadmap, design, and plan) engagements. This is a hands-on role. You will lead technical discovery, facilitate workshops, analyze industrial environments, build architecture and roadmap deliverables, guide delivery teams, and present recommendations to client leaders. You should be equally comfortable discussing a PLC network with an automation engineer, an operating model with plant leadership, and investment priorities with a CISO or CIO.
What You Will Do:

Lead OT assessments and advisory engagements

• Serve as the primary technical lead for OT Assessments, OT strategy work, and SRDP workstreams.

• Plan and facilitate discovery workshops, site visits, technical deep dives, and executive working sessions.

• Establish a safe, non-disruptive discovery approach that respects production schedules, safety requirements, and change control.

• Assess the client environment across assets, networks, control systems, dependencies, ownership, and operational constraints, and evaluate maturity across people, process, and technology.

• Identify risks, gaps, single points of failure, and lifecycle concerns affecting security, reliability, visibility, and resilience.

• Produce current-state and future-state architecture views, findings, maturity assessments, and prioritized roadmaps that connect recommendations to business impact, investment, and sequencing.

• Own the technical quality of deliverables and present findings to engineering teams, plant and operations leaders, and executives.

Apply deep OT and cybersecurity expertise

• Analyze OT and ICS architectures spanning PLCs, HMIs, SCADA, DCS, historians, MES, engineering workstations, safety systems, and connected edge environments.

• Evaluate IT/OT connectivity, Purdue-aligned design, zones and conduits, industrial DMZs, segmentation, remote access, and third-party connectivity.

• Assess asset inventory, passive visibility, communication flows, protocol use, legacy platforms, and compensating controls.

• Evaluate identity and access, endpoint protection, vulnerability and patch management, monitoring, incident response, backup, and recovery practices. • Balance security recommendations against safety, availability, performance, maintenance windows, and long OT lifecycles.

• Apply recognized standards including NIST SP 800-82, ISA/IEC 62443, and the NIST Cybersecurity Framework, plus applicable regulatory requirements.

• Bring a point of view on secure remote operations, edge computing, industrial wireless and private 5G, cloud-connected OT, and OT data.

Lead technical teams and delivery quality

• Lead and delegate work across technical consultants, engineers, and client resources on one or more workstreams.

• Break complex problems into work packages with clear approach, decision points, and acceptance criteria.

• Coordinate with Project Managers, account teams, and other AHEAD practices to deliver an integrated solution.

• Review technical work for accuracy and clarity, and mentor consultants on architecture, analysis, documentation, and client interaction.

• Contribute to repeatable methods, templates, and reference architectures for the OT practice.

Contribute to business development

• Participate in discovery and qualification meetings as the OT subject matter expert.

• Help shape scopes of work, estimates, work breakdown structures, assumptions, risks, and proposals.

• Support technical solutioning and proposal presentations with senior client stakeholders.

• Develop practical thought leadership, internal enablement, and client briefings that strengthen AHEAD's OT brand.

What You Will Bring:

Required Qualifications

• 10 or more years delivering complex technology, cybersecurity, network, or engineering solutions, with significant Operational Technology or ICS experience.

• Demonstrated experience leading OT or ICS assessments, architecture, segmentation, cybersecurity, or modernization engagements.

• Strong understanding of control-system architectures and industrial protocols such as Modbus, DNP3, EtherNet/IP, PROFINET, or OPC UA.

• Strong OT networking and security depth, including routing and switching, firewalls, industrial DMZs, segmentation, remote access, identity, and monitoring.

• Ability to explain the operational impact of technical decisions where safety, availability, and production continuity are critical.

• Experience producing architecture diagrams, maturity assessments, prioritized roadmaps, and executive presentations.

• Experience facilitating workshops with…
