Electrical Design Engineer – Water & Wastewater

Location: Sheffield

Contract type: Freelance

Start date: ASAP

Pay rate: £28 - £32 per hour (The rate of pay is dependent on experience and qualifications, with the higher rate available to candidates who meet the specified experience and qualification requirements.)

About the Role

Linear Recruitment are looking for a Temporary Electrical Design Engineer to help design and deliver electrical engineering solutions for water and wastewater treatment projects.

You will work on electrical systems for pumps, motors, control panels, power distribution and process plant, ensuring designs are safe, reliable and suitable for installation on site.

You will work closely with mechanical, civil, instrumentation, control and automation engineers to ensure all parts of a project work together effectively. You will also provide technical support during construction, testing and commissioning.

Key Responsibilities

• Design electrical systems for water and wastewater treatment plants and pumping stations.
• Produce electrical drawings, schematics, layouts and technical specifications.
• Design and review power distribution systems, motor control systems and electrical installations.
• Prepare cable schedules, load schedules, single-line diagrams and equipment specifications.
• Support the design of motor control centres (MCCs), distribution boards and control panels.
• Calculate electrical loads, cable sizes, voltage drops and protection requirements.
• Coordinate with mechanical and control engineers to ensure equipment is properly integrated.
• Check that designs meet relevant electrical standards, project specifications and client requirements.
• Review electrical design proposals from suppliers and subcontractors.
• Support site teams by answering technical queries and resolving installation issues.
• Assist with electrical inspections, testing, commissioning and project handover.
• Help prepare operation and maintenance manuals and final as-built drawings.
• Identify opportunities to improve safety, energy efficiency, reliability and whole-life equipment performance.

About You

You should have experience in electrical design, preferably within the water, wastewater, utilities or infrastructure sectors.

You should understand how electrical power systems support pumps, motors and process equipment, and be comfortable working with other engineering disciplines to deliver complete project solutions.

You should be able to manage design tasks independently while communicating effectively with project teams, clients, suppliers and site personnel.

Essential Skills and Qualifications

• A degree, HNC or HND in Electrical Engineering or a related discipline.
• Detailed electrical design experience.
• Experience designing electrical systems for industrial, utilities, water or infrastructure projects.
• Knowledge of power distribution, motor control, electrical protection and equipment selection.
• Ability to produce and interpret electrical schematics, single-line diagrams and cable schedules.
• Experience with AutoCAD, AutoCAD Electrical or similar design software.
• Knowledge of electrical calculations, including cable sizing, load calculations and voltage drop.
• Understanding of relevant electrical standards, regulations and health and safety requirements, including CDM.
• Familiarity with motor control centres, switchgear, control panels and industrial electrical equipment.
• Good communication, technical reporting and problem-solving skills.
• A practical understanding of installation, testing and commissioning on site.
• A full UK driving licence.

About the Projects

You will work on water and wastewater infrastructure projects, including treatment plants, pumping stations and process facilities.

Your designs will support the electrical systems that power pumps, motors and other plant equipment, helping ensure that water treatment and distribution processes operate safely and reliably.

The role covers the full project lifecycle, from initial design and calculations through to installation, testing, commissioning and handover.

You will collaborate with mechanical, civil and instrumentation, control and automation (ICA) engineers to deliver coordinated engineering solutions that meet project requirements and industry standards.
