About the Role

Wise Technical is seeking an experienced Lead LLC Development Engineer to lead the design, architecture, and delivery of PLC-based control software for automated baggage handling systems. This senior, hands-on technical leadership role involves setting standards for low-level controls development and directly architecting and writing PLC code for large-scale, safety- and performance-critical airport baggage systems. The successful candidate will own the technical delivery of PLC applications from conception through commissioning, ensuring robust integration with HMI/SCADA, SAC systems, and hold baggage screening infrastructure. They will provide technical leadership to the LLC development team, collaborating with the LLC Product Manager and reporting to the LLC Solutions Senior Manager.

Responsibilities

Lead the architecture and design of large-scale PLC control applications for baggage handling systems.
Define coding standards, structure, and best practices for the LLC development team.
Provide technical direction and mentorship to PLC engineers, reviewing code and designs.
Act as the senior technical point of contact for PLC development matters.
Design and develop PLC software for conveyor control, bag tracking, sortation, and system sequencing.
Develop and integrate control logic for hold baggage screening (HBS), ensuring compliance with standards.
Develop and maintain interfaces to Sort Allocation Computer (SAC) systems, Host Level Controller (HLC) systems, and airport IT/BRS platforms.
Architect and implement bag tracking logic for accurate and auditable bag status and routing.
Integrate PLC applications with HMI and SCADA systems for reliable real-time visualisation and control.
Design and implement robust fault handling, diagnostics, and system recovery strategies.
Produce and maintain functional design specifications, software design documents, and test documentation.
Plan and lead Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) activities.
Support on-site commissioning, installation, testing, and go-live of PLC applications.
Identify technical risks and mitigate delivery risks.
Line-manage and/or technically lead junior and mid-level PLC engineers.
Liaise with mechanical, electrical, IT, and project engineering teams for coordinated system delivery.
Represent Wise Technical in technical discussions with clients, integrators, and screening equipment suppliers.
