This is a senior, hands-on technical leadership role responsible for setting the standards, structure and quality of our low-level controls development, while directly architecting and writing PLC code for large-scale, safety- and performance-critical airport baggage systems.\nThe successful candidate will own the technical delivery of PLC applications from first principles through to commissioning, ensuring robust integration with HMI/SCADA platforms, Sort Allocation Computer (SAC) systems, and hold baggage screening infrastructure. They will provide technical leadership to the wider LLC development team, working closely with the LLC Product Manager on day-to-day technical direction and reporting into the LLC Solutions Senior Manager for line management matters.\nKey Responsibilities\nTechnical Leadership & Architecture\nLead the architecture and design of large-scale PLC control applications for baggage handling systems, built from the ground up. \nDefine coding standards, structure and best practice for the LLC development team, and ensure their consistent application across projects. \nProvide technical direction and mentorship to PLC engineers, reviewing code and designs for quality, maintainability and performance. \nAct as the senior technical point of contact for PLC development matters, working closely with the LLC Product Manager to align development with product and project priorities. \nPLC Development & Systems Integration\nDesign and develop PLC software for conveyor control, bag tracking, sortation and system sequencing across large, multi-PLC BHS installations. \nDevelop and integrate control logic for hold baggage screening (HBS), ensuring compliance with relevant screening standards and airport operational requirements. \nDevelop and maintain interfaces to Sort Allocation Computer (SAC) systems, Host Level Controller (HLC) systems, and airport IT/BRS platforms. \nArchitect and implement bag tracking logic, ensuring accurate, reliable and auditable bag status and routing data throughout the system. \nIntegrate PLC applications with HMI and SCADA systems, ensuring reliable real-time visualisation, alarming and operator control. \nDesign and implement robust fault handling, diagnostics and system recovery strategies. \nProject & Delivery Management\nProduce and maintain functional design specifications, software design documents and test documentation for PLC applications. \nPlan and lead FAT (Factory Acceptance Testing) and SAT (Site Acceptance Testing) activities for control software. \nSupport on-site commissioning, working with site teams to install, test, and go-live PLC applications. \nIdentify technical risks early and work with the LLC Product Manager and Senior Manager to mitigate delivery risk. \nTeam & Stakeholder Management\nLine-manage and/or technically lead junior and mid-level PLC engineers, supporting their development and performance. \nLiaise with mechanical, electrical, IT and project engineering teams to ensure coordinated system delivery. \nRepresent Wise Technical in technical discussions with clients, integrators and screening equipment suppliers. \nRequirements\nEssential Experience & Skills\nProven track record architecting and developing large-scale PLC applications from scratch (not just modifying existing code bases). \nStrong hands-on experience with major PLC platforms used in baggage handling (e.g. Siemens S7/TIA Portal, Rockwell/Allen-Bradley, or equivalent). \nDemonstrable experience writing PLC code for bag tracking within automated baggage handling systems. \nDemonstrable experience integrating and coding for hold baggage screening (HBS) systems. \nDemonstrable experience developing HLC (Host Level Controller) interfaces and associated communication protocols. \nExperience integrating PLC systems with SAC (Sort Allocation Computer) platforms. \nStrong working knowledge of HMI/SCADA system design, development and integration (e.g. WinCC, FactoryTalk, Ignition, or equivalent). \nSolid understanding of industrial networking and communications protocols (e.g. Profinet, Ethernet/IP, OPC UA, TCP/IP). \nExperience producing and working from functional design specifications and control philosophy documents. \nExperience leading or heavily contributing to FAT/SAT and site commissioning activities. \nStrong understanding of industrial safety systems and functional safety principles (e.g. safety PLCs, e-stop and interlock design). \nDegree or equivalent qualification in Electrical/Electronic Engineering, Control Systems, Computer Science, or a related discipline (or equivalent demonstrable industry experience). \nAbility and willingness to be based at Wise Technical's LHR offices a minimum of 4 days per week. \nRight to work in the UK and eligibility to obtain UK airside/airport security clearance. \nDesirable Experience & Skills\nPrior experience within the airport baggage handling industry, working with systems from vendors such as BEUMER, Vanderlande, Siemens Logistics, Babcock Airports or similar. \nExperience with baggage handling simulation tools and/or discrete event simulation of material handling systems. \nFamiliarity with airport-specific standards and regulations relevant to hold baggage screening and BHS (e.g. ECAC, TSA equivalents, or applicable national regulatory frameworks). \nExperience with version control and structured software lifecycle management for PLC codebases. \nPrevious experience in a technical leadership, principal engineer, or team lead capacity. \nKnowledge of database/reporting integration for bag tracking and management information systems. \nRecognised functional safety qualification (e.g. TÜV Functional Safety Engineer) or equivalent.","description_format":"text","description_chars":5876,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-12T14:36:11Z"}],"visa":[],"liveness":{"score":10,"band":"cold","label":"Long
