You will work collaboratively with multidisciplinary teams, subcontractors, and clients to define specifications, resolve complex technical challenges, and deliver high-integrity control systems that support safe, reliable, and efficient operation of bespoke engineered solutions.

Key Responsibilities

• Lead the full lifecycle of EC&I systems design, from concept and specification through to commissioning and handover.
• Define Electrical control system architectures, specify equipment such as cabling and instrumentation, and lead hardware and software integration activities.
• Prepare and approve detailed engineering documentation including:
• Electrical Schematics and General Arrangements
• Control Philosophy and Functional Design Specifications (FDS)
• Cable Schedules, I/O Lists, and Panel Layouts
• Instrumentation Datasheets and Wiring Diagrams
• Familiarity with PLC/HMI software and interface logic using platforms such as Siemens, Rockwell, or Schneider.
• Coordinate with mechanical, structural, and safety engineering teams to ensure integrated and cohesive system design.
• Conduct and lead design reviews, ensuring compliance with relevant codes, standards, and customer specifications.
• Manage third-party suppliers and panel builders, providing technical oversight throughout procurement, manufacture, and FAT.
• Support installation and commissioning activities, including troubleshooting and site acceptance testing (SAT).
• Act as a mentor to junior engineers, fostering technical growth and promoting knowledge sharing across the team.
• Liaise directly with clients to clarify technical requirements, report progress, and resolve emerging issues throughout the project lifecycle.
• Contribute to project planning and risk management by providing technical inputs to project managers and planners.
• Support bids and proposals with technical insight, concept designs, and cost/time estimates for EC&I scope.
• Promote continuous improvement across EC&I processes, templates, and design tools.

Skills & Experience Required

• Degree-qualified in Electrical Engineering, Control & Instrumentation, or a related discipline.
• Solid understanding of control system principles, instrumentation, motor control, and variable speed drives (VSDs).
• Substantial experience in delivering EC&I systems in complex or safety-regulated environments.
• Working knowledge of PLC/HMI systems (e.g. Siemens S7/TIA Portal, Rockwell Studio 5000, Schneider EcoStruxure).
• Proficient in producing electrical drawings using CAD tools (e.g. EPLAN, ElectricalOM, AutoCAD Electrical).
• Familiarity with applicable standards and regulations such as BS EN 60204, BS 7671, and EMC/Low Voltage Directives.
• Demonstrable ability to lead multidisciplinary design teams and coordinate with other engineering disciplines.
• Skilled in technical documentation, stakeholder communication, and supplier management.
• Full UK driving licence (travel between offices and client sites required).

Desirable Qualifications & Experience

• Chartered Engineer (CEng) or working toward professional registration.
• Experience in high-integrity or regulated sectors such as Nuclear, Defence, or Aerospace.
• Background in the design of Overhead Electrical Travelling Cranes (OHETCs), automated handling systems, or large-scale machinery.
• Hands-on experience in electrical panel design and PLC programming.
• Knowledge of Functional Safety standards (e.g. BS EN 61508, BS EN 62061, BS EN 13849).
• Competence with safety and verification tools such as SISTEMA or Amtech.
