Work You'll Do

• Architect and expand both new (greenfield) and existing (brownfield) backhaul networks supporting scale-out of IIoT devices, data-intensive workloads (e.g., cameras, sensors), and site digitalization.
• Design and implement robust network architectures using Purdue Model, IEC 62443 zoning/segmentation, and real-time protocols (PROFINET, EtherNet/IP, OPC-UA over TSN).
• Manage network segmentation and plant-to-cloud connectivity-including VLAN/trunking (802.1Q), VRF-lite, VXLAN-EVPN, and zero-trust micro-segmentation.
• Integrate site-to-site IPsec and SD-WAN overlays for secure and resilient OT network traffic.
• Champion network automation and monitoring initiatives using tools such as Ansible, Netmiko, N8N, and LangChain.
• Bridge IT and OT environments: design, secure, and integrate networks that bridge corporate IT platforms with plant/field OT environments, planning risk mitigation and compliance in line with the Purdue model.
• Apply expertise across industries, including Energy, Resources & Industrials (ERI); Manufacturing; and Technology, Media & Telecommunications (TMT).
• Mentor junior team members and liaise with global teams to ensure client requirements are understood and delivered.
• Present technical solutions and risk assessments to Architecture Review Boards (ARBs) and engage with senior client stakeholders.

The Team

Our Hybrid Cloud Infrastructure team provides specialized OT/IT engineering for modern, secure cloud ecosystems. We develop next-generation connectivity solutions from plant floor to cloud-enabling clients to drive automation, analytics, and operational excellence at scale.

As a Connected Edge Specialist, you'll lead the design, implementation, and integration of high-quality OT networking solutions, and contribute to the development of innovative methodologies and technical assets.

Required Qualifications

• 5+ years architecting, deploying, and supporting secure, multi-site OT/IIoT/industrial networks, leveraging models such as Purdue and IEC 62443.
• 4+ years designing and implementing VLANs, WLANs, DNS, firewalls, site-to-site IPsec, SD-WAN, and secure remote connectivity.
• 4+ years of strong hands-on experience with real-time industrial protocols (e.g., PROFINET, EtherNet/IP, OPC-UA) and troubleshooting plant-to-cloud networking (e.g., VLAN/trunking, VRF-lite, VXLAN-EVPN).
• Experience with network automation tools and scripting, including but not limited to Ansible, Netmiko, N8N, and LangChain, to orchestrate hybrid and industrial cloud environments.
• 2+ years bridging OT and IT environments, including integration planning and security/compliance risk mitigation.
• 2+ years in network performance assurance: implementing KPIs, monitoring, and proactive troubleshooting to maximize reliability and visibility.
• Demonstrated ability to present solutions to senior stakeholders (e.g., Architecture Review Boards), summarizing architecture, risks, and value proposition.
• Bachelor's degree (or equivalent experience).
• Ability to travel up to 50% based on client/industry needs.
• Must be legally authorized to work in the United States without employer sponsorship, now or in the future.

Preferred Qualifications

• Experience with AI networking and advanced network fabrics (e.g., NVIDIA Spectrum-X, InfiniBand, or Optical Transport Network (OTN) implementations).
• Professional certifications in networking or security (e.g., Cisco CCNP/CCIE, Juniper JNCIP/JNCIE, CompTIA Security+, or similar).
• Proven leadership on client engagements, including guiding project teams, mentoring, and delivering complex technical solutions.
