Purpose of the Role
The Senior EC&I Engineer will ensure that system architectures are robust, compliant, and aligned with both customer requirements and regulatory standards.
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.
