Job Summary

Reporting to the Director of Sales Engineering, the Lead Sales Engineer - PLC Control Systems is a customer-facing technical leader who translates complex data center and industrial automation requirements into scalable AIS solutions. The role leads technical discovery, solution architecture, demonstrations, proposal development, validation, and the transition from pre-sales to implementation. This position combines strong PLC and controls expertise with commercial judgment. The successful candidate will build customer confidence, shape technical win strategies, and develop repeatable architectures that connect PLC, SCADA, DDC, BMS, DCIM, Industrial IoT, edge, cloud, and enterprise systems.

What Success Looks Like

• Customers and partners regard AIS as a trusted technical advisor for PLC-based control solutions.
• Complex requirements are translated into clear architectures, scopes, proposals, demonstrations, and deployment approaches.
• Solutions are technically sound, secure, interoperable, commercially viable, and repeatable across customers and applications.
• Sales, product, engineering, partners, and delivery teams are aligned before customer commitment and through solution handoff.
• Field learning and Voice of Customer insights influence product direction, enablement, and commercialization priorities

Key Tasks & Responsibilities (Essential Functions)

Customer Discovery & Technical Sales Leadership

• Lead technical discovery workshops, site assessments, architecture reviews, and solution-envisioning sessions with customers, consultants, system integrators, OEM partners, and internal stakeholders.
• Qualify application, integration, cybersecurity, delivery, operational, and commercial requirements for complex opportunities.
• Partner with account teams to develop technical win strategies, position differentiated value, address objections, and advance strategic pursuits.
• Deliver executive and technical presentations, product demonstrations, proof-of-concepts, and customer training.
• Develop solution narratives, technical scopes, bills of material, assumptions, and handoff criteria.

PLC Control System Architecture Architect

• PLC-based automation and control solutions for data center cooling, electrical monitoring, energy management, and related mission-critical applications.
• Develop reference architectures, solution blueprints, and deployment standards that support scalable enterprise implementations.

  Review and, when required, develop representative PLC applications to validate architecture, demonstrate capabilities, and reduce technical risk.

• Apply IEC 61131-3 programming concepts, including Structured Text, Function Block Diagram, Sequential Function Chart, and
• Ladder Logic, as appropriate to the application.
• Guide the integration of controls with field devices, equipment packages, supervisory systems, and enterprise data platforms.

Data Center & Mission-Critical Applications

• Apply controls expertise to cooling towers, chillers and cooling plants, CRAH/CRAC equipment, pumping, water-side economization,
• FDU/CDU equipment, liquid cooling systems, electrical distribution monitoring, and critical alarming.
• Help customers improve uptime, resilience, energy performance, operational visibility, and sustainability.
• Assess sequence-of-operations, failure modes, redundancy requirements, alarming strategies, and operational constraints in mission-critical environments.
• Engage adjacent applications in HVAC-R, electrical power, semiconductor, process, manufacturing, and other critical infrastructure where PLC-based solutions create value.

Industrial Networking, Integration & Cybersecurity

• Design and validate interoperable architectures using relevant industrial and enterprise protocols, such as Modbus TCP/IP and RTU, BACnet/IP, EtherCAT, OPC UA, MQTT, Sparkplug B, Redfish, and REST APIs.
• Connect PLC, SCADA, DDC, BMS, DCIM, Industrial IoT, cloud, and enterprise systems while maintaining clear ownership and data boundaries.
• Identify technical and operational risks related to network segmentation, secure remote access, interoperability, availability, and lifecycle support.

Supervisory, Edge & IIoT Solutions

• Design supervisory monitoring and control approaches using platforms such as Ignition and Ignition Edge.
• Use MQTT and Sparkplug B where applicable, to support scalable data collection and operational visibility.
• Collaborate with software and product teams on edge-to-cloud integration, analytics, digital twins, and operational optimization use cases.
• Create proof-of-concepts and reference applications that demonstrate solution value without replacing the project delivery team's production responsibilities.

Skills and Minimum Experience Required

• Bachelor's degree in engineering, computer science, automation, business, or a related discipline, or equivalent relevant industry experience.
• Typically 7+ years of relevant experience in technical sales, sales engineering, application engineering, controls engineering, systems integration, solution architecture, or a comparable customer-facing technical role. Candidates

  with fewer years may be considered when they demonstrate equivalent technical depth and leadership.
